  • Help parsing long (3.5mil lines) text file, line by line and storing data, need a strategy

    - by Jarrod
    This is a question about solving a particular problem I am struggling with, I am parsing a long list of text data, line by line for a business app in PHP (cron script on the CLI). The file follows the format: HD: Some text here {text here too} DC: A description here DC: the description continues here DC: and it ends here. DT: 2012-08-01 HD: Next header here {supplemental text} ... this repeats over and over for a few hundred megs I have to read each line, parse out the HD: line and grab the text on this line. I then compare this text against data stored in a database. When a match is found, I want to then record the following DC: lines that succeed the matched HD:. Pseudo code: while ( the_file_pointer_isnt_end_of_file) { line = getCurrentLineFromFile title = parseTitleFrom(line) matched = searchForMatchInDB(line) if ( matched ) { recordTheDCLines // <- Best way to do this? } } My problem is that because I am reading line by line, what is the best way to trigger the script to start saving DC lines, and then when they are finished save them to the database? I have a vague idea, but have yet to properly implement it. I would love to hear the communities ideas\suggestions! Thank you.

  • Algorithms or patterns for a linked question and answer cost calculator

    - by kmc
    I've been asked to build an online calculator in PHP (and the Laravel framework). It will take the answers to a series of questions to estimate the cost of a home extension. For example, a couple of questions may be: What is the lie of your property? Flat, slightly inclined, heavily inclined. (these suggestive values could have specific values in the underlying calculator like, 0 degrees, 5 degrees, 10 degrees. What is your current flooring system? Wooden, or concrete? These would then impact the results of other questions. Once the size of the extension has been input, the lie of the land will affect how much site works will cost, and how much rubbish collection will cost. The second question will impact the cost of the extensions flooring, as stumping and laying floorboards is a different cost to laying foundations and a concrete slab. It will also influence what heating and cooling systems are available in the calculator. So it's VERY interlinked. The answer to any question can influence the options of other questions, and the end result. I'm having trouble figuring out an approach to this that will allow new options and questions to be plugged in at a later stage without having things too coupled. The Observer pattern, or Laravel's events may be handy, but currently the sheer breadth of the calculator has me struggling to gather my thoughts and see a sensible implementation. Are there any patterns or OO approaches that may help? Thanks!

    - by itsoft3g
    I have a server with 5 ISP connections, i am using Apache web server and php engine to run my application. Outgoing request to different API now needs to be send through a specific ISP (or a different IPs). All my API request are sent using PHP and Web server.

  • PHP5 giving failed to open stream: HTTP request failed error when using fopen.

    - by mickey
    Hello everyone. This problem seems to have been discussed in the past everywhere on google and here, but I have yet to find a solution. A very simple fopen gives me a PHP Warning: fopen(http://www.google.ca): failed to open stream: HTTP request failed!". The URL I am fetching have no importance because even when I fetch http://www.google.com it doesnt work. The exact same script works on different server. The one failing is Ubuntu 10.04 and PHP 5.3.2. This is not a problem in my script, it's something different in my server or it might be a bug in PHP. I have tried using a user_agent in php.ini but no success. My allow_url_fopen is set to On. If you have any ideas, feel free!

  • Service layer coupling

    - by Justin
    I am working on writing a service layer for an order system in php. It's the typical scenario, you have an Order that can have multiple Line Items. So lets say a request is received to store a line item with pictures and comments. I might receive a json request such as { 'type': 'Bike', 'color': 'Red', 'commentIds': [3193,3194] 'attachmentIds': [123,413] } My idea was to have a Service_LineItem_Bike class that knows how to take the json data and store an entity for a bike. My question is, the Service_LineItem class now needs to fetch comments and file attachments, and store the relationships. Service_LineItem seems like it should interact with a Service_Comment and a Service_FileUpload. Should instances of these two other services be instantiated and passed to the Service_LineItem constructor,or set by getters and setters? Dependency injection seems like the right solution, allowing a service access to a 'service fetching helper' seems wrong, and this should stay at the application level. I am using Doctrine 2 as a ORM, and I can technically write a dql query inside Service_LineItem to fetch the comments and file uploads necessary for the association, but this seems like it would have a tighter coupling, rather then leaving this up to the right service object.

  • External modules security

    - by Jlouro
    I am developing some external modules for an application. These modules are BPL files and if present in the application folder the application loads them and uses whatever is available inside. How can I prevent the sharing of these modules by my clients? I need them to be authorized to use the modules (module by module). To have some sort of license, registration of the module, what is the best method? Thanks

  • SEO & Multilingual: would be this a good practise?

    - by Younès
    I am currently making a bilingual website and I'd like to get nice SEO results of course. Here's my idea: The internal links would be composed of the "www" subdomain so that people can share links regardless of their language. Anyway, their language is determined by the HTTP_ACCEPT_LANGUAGE PHP variable. So, they would see http:// www.site.com/mydocument/123 in their adress bar and never see any links like "http:// fr.site.com/mydocument/123" or "http://en.site.com/mydocument/123" The user can always switch the page's language thanks to links in the footer. The switching language link would be : http:// fr.site.com/mydocument/123 , and clicking on it would change his language session and redirects the user to http:// www.site.com/mydocument/123 In case of a crawling bot: I read that if the HTTP_USER_LANGUAGE variable was missing then it's a crawling bot. So, in that case, we set the defaut language as English. Each page, as I mentionned earlier, has a link for another language: On the page: http:// www.site.com/document/1323, the link http:// fr.site.com/document/1323 can be seen by the bot and be crawled. What do you think about this practise ? Would I get good SEO results for each language ?

  • Places to store basic data

    - by Ella
    I am using PHP. I'm building a fully modular CMS, which is destined for the public. Some people might view this as a framework, but I intend to write a set of extensions for it, extensions that will make it a CMS :P Because it's completely modular I have a problem figuring out how to load extensions. Practically I need to get the list of active extensions, so I can load them inside my base class. I load them by reading some file headers, which contain a "dependency" field. That field decides the order in which I have to instantiate the objects. The problem is that when the CMS starts I have no database interface, because that's an extension too, so I can't store the active extensions list in the database :) You might ask how are extensions activated in the first place. Well - in the administration interface, which is an extension as well (obviously on first install of the CMS there will be some extensions active by default). Could writing that list inside a text file be a solution? The problem is that a lot of hosts are not very nice with scripts when they write files. And since this CMS is public I might have a problem here?

  • I need a form to tie MySQL Records together.

    - by John R
    I need a HTML-based form to tie database records together. The user scenario that I envision is somthing like this: A super-user does a search of the database and is delivered a table of records based on that search; each record is numbered with the database-record id. There would also be two text fields next to each record. These text fields would allow: the user to make a reference from one record to another. For example, a user could enter into record id #457 the integer 242 to indicate that there is a correlation with record ID #242. The user would also describe the type of relationship it is. This could be accomplished with a simple integer in the second field that indicates the type of relationship between the two records. When the super-user hits the submit button, all of these relationships are saved in a mySqljoin table. One option is to give me advice on how to implement and code this myself in PHP. However, before I reinvent the wheel, another option is to lead me to a free script that does something similar.

  • In APC+PHP, how much RAM is too much? Is it okay to set apc.shm_size to many GB?

    - by Jeremy Clarke
    On our server we have a LOT of RAM for our traffic levels (16GB). The HTTP processes regularly eat up all CPU and need to be restarted without even getting close to using swap memory, so I'm looking for ways to spend RAM to ease the load on Apache (and/or help the seperate MySQL server which may be breaking Apache). I have many WordPress installs on the HTTPD instance so APC sometimes uses as much as 900MB of ram (according to the apc.php charts). Just in case I have apc.shm_size set to 1600MB which is more than it needs but not more than I can spare. This means there is usually lots of extra RAM available to APC but also very little turnover and fragmentation is never more than 1%. Is this dangerous? Should I be slimming down APC to less than 1GB just on principle? Should I be expecting some turnover within APC in the name of bringing it's overall footprint down? Having so much memory devoted to APC means that in top/htop every single httpd process shows ~1.9GB in the VIRT memory column. Obviously this is shared memory and not used per-process, but could it be hurting our server? NOTE: The problem with the server remains unclear but the effect is that about 60 times a day all 8 CPU's fill up to 100% and everything stops working until Monit sees that Apache is broken and restarts it (Monin also saves the MySQL server). I'm not sure if APC is even part of the problem but I'm trying to optimize everything just in case.

  • correct way to implement auth/acl in mvc

    - by WiseStrawberry
    I am looking into making a correctly laid out MVC auth/acl system. I think I want the authentication of a user (and the session handling) to be seperate from the ACL system. (I don't know why but this seems a good idea from the things I've read) What does mvc have to do with this question you ask? Because I wish for the application to be well integrated with my acl. An example of a controller (CodeIgniter) <?php class forums extends MX_Controller { $allowed = array('users', 'admin'); $need_login = true; function __construct() { //example of checking if logged in. if($this->auth->logged_in() && $this->auth->is_admin()) { echo "you're logged in!"; } } public function add_topic() { if($this->auth->allowed('add_topic') { //some add topic things. } else { echo 'not allowed to add topic'; } } } ?> My thoughts $this->auth would be autoloaded in the system. I would like to check the $allowed array against the user currently (not) logged in and react accordingly. Is this a good way of doing things? I haven't seen much literature on mvc integration and auth. I want to make things as easy as possible.

  • Moving away from PHP and running towards server-side JavaScript [on hold]

    - by Sosukodo
    I've decided to start moving away from PHP and server-side JavaScript looks like an attractive replacement. However, I'm having a hard time wrapping my head around how others are using Node.js for web applications. I'm currently using Lighttpd with FastCGI PHP. The one thing I like about PHP is that I can "inline" my scripts in the document like so: <?php echo 'Hello, World!'; ?> My question is: Is there any server-side JavaScript solution that I can use in this manor? For instance, I'd love to be able to do this: <?js print('Hello, World!'); ?> Is there such a thing? I'm not looking for opinions about "which is better". I just want to know what's out there and I'll explore each of them on my own. The important thing is that I'd like to use it like I demonstrated above. Links to the software along with implementation examples will be considered above other answers.
