  • Script Speed vs Memory Usage

    - by Doug Neiner
    I am working on an image generation script in PHP and have gotten it working two ways. One way is slow but uses a limited amount of memory, the second is much faster, but uses 6x the memory . There is no leakage in either script (as far as I can tell). In a limited benchmark, here is how they performed: -------------------------------------------- METHOD | TOTAL TIME | PEAK MEMORY | IMAGES -------------------------------------------- One | 65.626 | 540,036 | 200 Two | 20.207 | 3,269,600 | 200 -------------------------------------------- And here is the average of the previous numbers (if you don't want to do your own math): -------------------------------------------- METHOD | TOTAL TIME | PEAK MEMORY | IMAGES -------------------------------------------- One | 0.328 | 540,036 | 1 Two | 0.101 | 3,269,600 | 1 -------------------------------------------- Which method should I use and why? I anticipate this being used by a high volume of users, with each user making 10-20 requests to this script during a normal visit. I am leaning toward the faster method because though it uses more memory, it is for a 1/3 of the time and would reduce the number of concurrent requests.

  • Strip anchors down to their contents, only if the anchor's URL contains...

    - by Tony
    Hi, Does anyone know a regex function in PHP to strip an anchor of it's contents, only if the anchor's href attribute contains specific text? For example, I have an HTML page and there are links throughout. But I want to strip only the anchors that contain "yahoo" in the URL. So <a href="http://pages.yahoo.com/page1">Example page</a> would become: Example, while other anchors in the HTML not containing "yahoo" would be left alone. Thank you in advance. -T

  • Need a regular expression for an Irish phone number

    - by Eoghan O'Brien
    I need to validate an Irish phone number but I don't want to make it too user unfriendly, many people are used to writing there phone number with brackets wrapping their area code followed by 5 to 7 digits for their number, some add spaces between the area code or mobile operator. The format of Irish landline numbers is an area code of between 1 and 4 digits and a number of between 5 to 8 digits. e.g. (021) 9876543 (01)9876543 01 9876543 (0402)39385 I'm looking for a regular expression for Javascript/PHP. Thanks.

  • upload an m4a file in flex, saving it as a blob in oracle, and retrieving metadata info from it

    - by Angus
    Hi, I currently have a FileUpload.mxml component that uploads a .m4a to an oracle database, retrieves metadata from the file and saves the metadata info in the database. to acheive this I use FileReference() and set up, amoung others, the dispatcher.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, completeHandler); So the file is posted to a php file which saves it as a blob. Once the blob is saved, the script sends a message back to flex to dispatch the upload_complete_data event. In the complete handler, the metadata is then retreived by reading the value back from the database into a custom made meta data reader. The metadata info is then saved via flex. This seems a little long winded. Has anyone else successfully achieved this using a different way?

  • install CakePHP on Mac osx: apache problems

    - by ed209
    First time cake user and I'm having real apache problems. For some reason the .htaccess is trying to find File does not exist: /Library/WebServer/Documents/Users but there is no such directory as Users.

  • Couchbase (ex. membase) solution to dump all keys in a bucket

    - by j99
    I was googling around and found various python + tap solutions that should enable me to dump all keys from a bucket but none of them worked for me. I have a bucket at port 11230 and I need to get a dump of all keys in order to fill them into sphinx search engine. If I execute: # python /opt/couchbase/lib/python/tap_example.py 127.0.0.1:11230 I get the following output: info: New bin connection from None error: uncaptured python exception, closing channel <tap.TapConnection connected at 0x7f5d287184d0> (<type 'exceptions.AssertionError'>: [/usr/lib/python2.6/asyncore.py|read|78] [/usr/lib/python2.6/asyncore.py|handle_read_event|428] [/opt/couchbase/lib/python/mc_bin_server.py|handle_read|325]) this error is the same even if I try some other host or port. I also tried many other python scripts that I found on forums and groups but all of them produced the same error. My primary development environment includes PHP & Perl on Debian linux box but I will take any solution that would just dump all the keys into plain text file. Thank you for any help!

  • Zend without Database

    - by dbemerlin
    Hi, i googled for an hour now but maybe my Google-Fu is just too weak, i couldn't find a solution. I want to create an application that queries a service via JSON requests (all data and backend/business logic is stored in the service). With plain PHP it's simple enough since i just make a curl request, json_decode the result and get what i need. This already works quite well. A request might look like this: Call http://service-host/userlist with body: {"logintoken": "123456-1234-5678-901234"} Get Result: { "status": "Ok", "userlist":[ {"name": "foo", "id": 1}, {"name": "bar", "id": 2} ] } Now we want to get that into the Zend Framework since it's a hobby project and we want to learn about Zend. The problem is that all information i could find use a Database. Is there even a way to create a Zend Project that does not use a Database? And how can i write a model that represents the actions instead of objects and object-relations?

  • Database Abstraction & Factory Methods

    - by pws5068
    I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a common-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? Can PEAR interface with the MySqli prepared statements I currently use? Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) Will it slow down my site once I have a significantly large member base?

  • Leverage cloud and programming to share GB's of photos

    - by jcmoney
    My friends and I went on a trip and we have over 8 GB of photos we want to share. We live in different geographic locations and all of us (14 people) have a part of the 8 GB. I was wondering if there's a way to leverage my php skills to share all these photos. My current plan is to make a simple site that you can upload a bunch of files and also list those files for people to download (probably a compressed folder of a bunch of selected ones) but was wondering if there's a better way or if I'm grossly underestimating scalability issues. All of us have high speed internet (essentially T1) and I was planning on using Amazon EC2 since this is a heavy task but for a short time period. That's also the reason I can't use dropbox or similar services since they have a 2GB cap (and I don't want to have everyone sign up and install something). I also don't want to set up anything too tricky since not all of them are tech savvy.

  • Advanced search functionality

    - by Chris
    I have a website with a jQuery based autocomplete search functionality which works great. Currently though I have just one search box for all categories, what I want is for someone to be able to type in, say for example, dorian gray dvd (in any order) which will search for dorian gray within the dvd category. What this will require then is a bit of magic on the server side to figure out if any of the words are category keywords, and then limit the search by that. What is the best (and quickest) way to do this in PHP / MySQL? I currently have a few trains of thought Search the category table for matches and perhaps order the results by that. Or split up the search terms into an array and separately search the categories for that for a match. Another thought I just had is to concat the category title to the dvd title in the database and match against that, or something similar... but this sounds computationally expensive? Any advice?

  • Aggregating and Displaying Multiple Feeds

    - by Keith
    I want to pull feeds for multiple online services (e.g. Tumblr, Google Reader, Delicious) and aggregate them into a single feed to display on my site. I know of services like YQL or Yahoo! Pipes which will combine feeds, but sometimes those services are too slow. I was wondering what the best method would be if I wanted to run this on my own server (using JavaScript or PHP)? Ideally, I would cache the results to cut down on processing.

  • Ajax basic email code without reloading page

    - by Camran
    I have in a previous Q found out that I need an ajax-function to send an email (submit a contact form) without reloading the page. This is for my classifieds website, where when users are viewing a classified they have the option to "tip a friend" by entering their friends email-adress and submitting the form. But I don't want to reload the page, that would be frustrating and not so clever. The only input in the form is a text input which will contain the email-adress to send to, and another hidden input which contains the classified_id nr, to identify which classified it is. The website is php based btw... Does anybody have a simple script for this? I have no experience in Ajax at all... And would really appreciate it. Thanks PS: Would prefer no Jquery, due to clients own reasons...

  • Multithreaded FTP upload. Is it possible?

    - by Arty
    I need to upload multiple files from directory to the server via FTP and SFTP. I've solved this task for SFTP with python, paramiko and threading. But I have problem with doing it for FTP. I tried to use ftplib for python, but it seems that it doesn't support threading and I upload all files one by one, which is very slow. I'm wondering is it even possible to do multithreading uploads with FTP protocol without creating separate connections/authorizations (it takes too long)? Solution can be on Python or PHP. Maybe CURL? Would be grateful for any ideas.

  • Creating a broswed history menu

    - by pundit
    Hi guys, I'm sure many of you have visited amazon.com. When you do, amazon create a list of browsed menu items at the very bottom of the home page. I am currently doing a project that applies personalisation and customisation and wanted to implement something similar. my prototype is based on an institution, so i want to display a list of probably the last 5 viewed programmes or courses on the home page. I am using php and so far i have thought of using $_SERVER["HTTP_REFERER"], but basically returns the last url..Which is not what i want. Does any one have any suggestions that could probably help with this. thanks.

  • File modified date/time changes when uploaded via FTP

    - by Nate Shoffner
    Hey /g/, FTP/PHP question here. On one of my pages I load .txt files from a directory. Pretty simple. I also display the modified date of the text file using this: date('m/d/Y', filemtime($file)); This works fine on my WAMP server but when I upload the files via FTP, the modified date is changed to when they were uploaded. I'm currently hosting on a free hosting provider (freehostia to be exact). Is there any way to keep the modified date/time from changing when it's uploaded? Or is there perhaps an alternative way to go about this? Any ideas are appreciated.

  • WAMP server suddenly stopped running scripts

    - by user2358008
    I have been working on a website for some months now. Every day, I open up the PHP scripts in the same manner, and every day they work just fine. Today, I go to open one up the same as I always do, except the page just comes up as the text file. All pages are the same, I have not changed most of them for many weeks now. WAMP is giving me no errors. I just installed the latest version, and it still won't work. There is no problem with file extensions, The only problem I can find is in the Apache Error Log: [Fri Oct 25 10:42:40.029691 2013] [mime:warn] [pid 4860:tid 1508] AH01599: Cannot get media type from 'x-httpd-php53' What does this mean?

  • Echo mysql results in a loop?

    - by Roy D. Porter
    I am using turn.js to make a book. Every div within the 'deathnote' div becomes a new page. <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page </div> //ends book What I am doing is trying to get 3 'content' (content being a name and cause of death) divs onto 1 page, and then generate a new page. So here is what i want: <div id="deathnote"> //starts book <div style="background-image:url(images/coverpage.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"></div> //creates new page <div style="background-image:url(images/paper.jpg);"> //creates new page but leaves it open <div> CONTENT </div> <div> CONTENT </div> <div> CONTENT </div> </div> //ends the page </div> //ends book Seems simple enough, however the content is data from a MySQL DB, so i have to echo it in using PHP. Here is what i have so far <div id="deathnote"> <div style="background-image:url(images/coverpage.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <div style="background-image:url(images/paper.jpg);"></div> <?php $pagecount = 0; $db = new mysqli('localhost', 'username', 'passw', 'DB'); if($db->connect_errno > 0){ die('Unable to connect to database [' . $db->connect_error .

IT IS SIMPLE CONNECTING SCRIPT THAT I KNOW WORKS //THE METHOD I AM HAVING TROUBLE WITH IS BELOW $pagecount = 0; while($row = $result->fetch_assoc()){ //GETS THE VALUE (and makes sure it isn't nothing echo '<div style="background-image:url(images/paper.jpg);">'; //THIS OPENS A NEW PAGE while ($pagecount !== 3) { //KEEPS COUNT OF HOW MUCH CONTENT DIVS IS ON THE PAGE while($row = $result->fetch_assoc()){ //START A CONTENT DIV echo '<div class="content"><div class="name">' . $row['victim'] .

The problem resides within the while loops. Any help is greatly appreciated. Thanks in advance guys. :)

  • Testing for security vulnerabilities on web applications

    - by Moak
    A lot of companies use CMS software that updates on the regular, often they are security fixes, implying that the previous version have security vulnerabilities. But most clients never upgrade this, or even the CMS has been modified so that an update would break the site. Are there sites that document these exploits, and instruct how to test for them? Or does this information not even get published? (in order not to have people try to exploit them) Also is there a generic php/js based check list to prevent hack attempts? I know about SQL injections and XSS, but I'm sure that there are more threats out there. Peace

If I submit a form and in the action attribute of it i pass "$_SERVER['PHP_SELF']" and at the same time i am using url rewriting for the same page.. then these two things will contradict each other resulting in the display of action value of form in address bar.. so how can i manage this to get the url rewrited form of $_SERVER['PHP_SELF']? here the rewrite rule is to change the name of url file likewise as if form is submitted to any file say direction.php then rewrite will change it to something 30/redirect.html

  • Decoding and caching json every 60 minutes

    - by Gary
    Hi, How do I do this on a php webpage? I want to get and decode a json string and display the results as html on my page, however, I don't want it hotlinking back to the source. If I could write the decoded string to a txt file say weather.txt on the server and keep the html formatting and do it so that the page won't fetch the json script until 60 minutes has passed since the last time it was fetched regardless of how many times the page is opened during that 60 minute period and the weather.txt is viewed. All I can come up with is a simple script that hotlinks, everything else I have tried simply failed. $file = file_get_contents('http://sample.com/weather'); $out = (json_decode($file)); echo $out-mainText; Will appreciate any help with this.
