• Rotating images with PHP reduces quality especially over about 10-20 actions

  - by Dylan Cross

  I am using this code below to rotate my jpeg images, the problem is that after around 10-20 times of rotating the image the image is dramatically lower quality, especially blue skies and such, my question is how can I keep these images the same high quality image? There must be a way. I mean, i keep the original image on the server for each image uploaded, and I don't do anything to that, so if need be it, I guess I could always come up with some way of using that over whenever possible.. But would rather not have to. $source = imagecreatefromjpeg($filename); $rotate = imagerotate($source, 90, 0); imagejpeg($rotate, $filename ,100);

• PHP strtotime() setting date to default

  - by Paddyd

  I have a script which is reading values from an excel sheet and inserting them into an sql table. My problem is when the script reads in some of the date fields it is setting them to a default value : 1970-01-01 01:00:00 I have noticed that this is happening when it comes across a date where the 'day' is greater than 12 : 13/05/2012 18:52:33 (dd-mm-yyyy hh-mm-ss) I thought this may be due to the script thinking that this is the month field (i.e american format) and it sees it as an invalid value, so I set the default timezone to my own hoping it may resolve the problem but it made no difference. date_default_timezone_set('Europe/Dublin'); Here is an example of what my code is doing: Excel field value : 01/05/2012 18:32:45 Script: $start_time = $data->val($x,5); echo $start_time = date("Y-m-d H:i:s", strtotime($start_time)); Output: 2012-01-05 18:32:45 This is the exact format I am looking for (except for the fact that the day and month fields are switched around i.e american date format) but it doesnt work for the type of dates I mentioned above.

• Content cacheing with PHP and CodeIgniter

  - by Josh K

  I have a couple of things I'm working on, namely a page that issues five or six cURL requests and processing content on them. I'm working with CodeIgniter on a LAMP stack but am open to other options. Naturally I would prefer to not rewrite the application. I would like to know if there are any ready-made / easily learned caching methods. Primarily I'd like to check if the page has changed since I last scrapped it. If it has, redownload and present. If it hasn't, serve up a cached copy.

• Make any posible combination of one string with php

  - by Johan

  I need an algorithm that return all possible combination of all characters in one string. I've tried: $langd = strlen($input); for($i = 0;$i < $langd; $i++){ $tempStrang = NULL; $tempStrang .= substr($input, $i, 1); for($j = $i+1, $k=0; $k < $langd; $k++, $j++){ if($j > $langd) $j = 0; $tempStrang .= substr($input, $j, 1); } $myarray[] = $tempStrang; } But that only returns the same amount combination as the length of the string. Say the $input is = "hey", the result would be: hey, hye, eyh, ehy, yhe, yeh.

• Parsing ip addresses in php

  - by user2938780

  I am trying to get the number of active connections (Real Time) from a log file by IP connected and having a Play status but instead, it's giving me the total number of IP with status play. The number doesn't decrease at all. Keeps on increasing as soon as a new ip is added. How can I fix it?

• Login system and sessions (php)

  - by Jonathan

  I've created a login page and registration page and now I want to use that to password protect pages and have pages which show information specific to that user. Would storing the user ID of the user logged in in a Session variable be a safe and correct way of doing this? How easy would it be for a user to change the session variable to a different ID and access another user's information, and not having to type the users login details in?

• Trying to build a dynamic PHP mysql_query string to update a row and getting back the updated row

  I have a form that jQuery tracks the onChage .change() event so when something is changed it runs a ajax request and i pass in the column, id, and the values in the url.

Here is the PHP code i am trying to work with. <?php require_once('Connections/connect.php'); ?> <?php $id = $_GET['id']; $collumn = $_GET['collumn']; $val = $_GET['val']; ?> <?php mysql_select_db($myDB, $connection); // here i try to build the query string and pass in the passed in values $sqlUpdate = 'UPDATE `plProducts`.`allPens` SET `$collumn` = '$val' WHERE `allPens`.`prodId` = '$id' LIMIT 1;'; // here i want to echo back the updated row (or the updated data) $seeResults = mysql_query($sqlUpdate, $connection); echo $seeResults ?>

• php - using file() incrementally?

  - by NeedBeerStat

  I'm not sure if this is possible, I've been googling for a solution... But, essentially, I have a very large file, the lines of which I want to store in an array. Thus, I'm using file(), but is there a way to do that in batches? So that every,say, 100 lines it creates, it "pauses"? I think there's likely to be something I can do with a foreach loop or something, but I'm not sure that I'm thinking about it the right way... Like $i=0; $j=0; $throttle=100; foreach($files as $k => $v) { if($i < $j+$throttle && $i > $j) { $lines[] = file($v); //Do some other stuff, like importing into a db } $i++; $j++; } But, I think that won't really work because $i & $j will always be equal... Anyway, feeling muddled... Can someone help me think a lil' clearer?

• MySql php: check if Row exists

  - by Jeff

  This is probably an easy thing to do but I'm an amateur and things just aren't working for me. I just want to check and see if a row exists where the $lectureName shows. If a row does exist with the $lectureName somewhere in it, I want the function to return "assigned" if not then it should return "available". Here's what I have. I'm fairly sure its a mess. Please help. function checkLectureStatus($lectureName) { $con = connectvar(); mysql_select_db("mydatabase", $con); $result = mysql_query("SELECT * FROM preditors_assigned WHERE lecture_name='$lectureName'"); while($row = mysql_fetch_array($result)); { if (!$row[$lectureName] == $lectureName) { mysql_close($con); return "Available"; } else { mysql_close($con); return "Assigned"; } } When I do this everything return available, even when it should return assigned.

• PHP cURL: get headers only from post

  - by Stewart

  There ought to be a way of sending a post request and getting back just the headers. $ch = curl_init('http://www.stackoverflow.com/'); curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_NOBODY, true); doesn't work, because all setting CURLOPT_NOBODY does is to change the request method to HEAD, thereby overriding CURLOPT_POST. I could just leave the last of these lines out and only process the headers, but is there a more efficient way? It's also odd that there doesn't seem to be a way in cURL to truncate the received content to a specified length as there is with file_get_contents.

• PHP Sort Array By SubArray Value

  - by Sjwdavies

  I've got the following structue of array: Array ( [0] => Array ( [configuration_id] => 10 [id] => 1 [optionNumber] => 3 [optionActive] => 1 [lastUpdated] => 2010-03-17 15:44:12 ) [1] => Array ( [configuration_id] => 9 [id] => 1 [optionNumber] => 2 [optionActive] => 1 [lastUpdated] => 2010-03-17 15:44:12 ) [2] => Array ( [configuration_id] => 8 [id] => 1 [optionNumber] => 1 [optionActive] => 1 [lastUpdated] => 2010-03-17 15:44:12 ) ) What's the best way for order the array, in an incremental way based on the optionNumber? So the results look like: Array ( [0] => Array ( [configuration_id] => 8 [id] => 1 [optionNumber] => 1 [optionActive] => 1 [lastUpdated] => 2010-03-17 15:44:12 ) [1] => Array ( [configuration_id] => 9 [id] => 1 [optionNumber] => 2 [optionActive] => 1 [lastUpdated] => 2010-03-17 15:44:12 ) [2] => Array ( [configuration_id] => 10 [id] => 1 [optionNumber] => 3 [optionActive] => 1 [lastUpdated] => 2010-03-17 15:44:12 ) )

• override __set in __construct() in php?

  - by user151841

  I have a class based on database values. I'm using __set to automatically sync database values with the class properties. Set checks an array of database fields that it is allowed to update in the database. The field 'id' isn't in the list, so __set will throw an exception if you try to do $objDbRow->id = 5;. However, there is one time when I do want to set the id property of the object, and that's on instantiation. So in __constuct, I have $this->id = $id (where $id is passed to __construct). However, __set seems to be intercepting the setting here, because an exception is being thrown on construction. What's the way to get around this? I suppose I also have a boolean flag, like $instantiated, that __set() would check before it does it's field whitelist checking. But that feels inelegant.

• PHP - Setting Database Info

  - by user1710648

  First off, I'm sorry if this shows no code which is not what Stack Overflow is about..But I have no clue where to go on this. I have a basic CMS I made, and I am trying to distribute it. I want to make it so that upon going to /cms/install for example, they set the database info, and different info to integrate into the CMS. Now my issue is, what would be the best method to allow the user to store that database info? A cookie seems to not be the right way..Could I store database info inside of a database? Not too sure where to go on this. More or less. What is the best way to temporarily store the database information the user gave before arrival of the full CMS.

• Need help with transferring data between MySQL db's using PHP

  - by JM4

  In one of the sites I manage, the client has decided to take on ACH/Bank Account administration where it was previously outsourced. As a result, the information submitted in our online form which used to simply store in a single database for processing now must sit in 'limbo' until the funds used for payment have been verified. My original plan is as follows: At the end of an enrollment, all form data is collected and stored in a single MySQL database. Our internal administrator will receive an email notification reminding him enrollments have taken place. He will process the ACH information collected and wait the 3-4 business days needed for payment to clear. Once the payment information has been returned as Good (haven't considered what I will do with the 'bad' yet), the administrator can log into a secure portal which allows him to click a button to 'process' the full information once compared and verified. the process is simplified as: Enrollment complete: data stored in DB 'A' Funds verified and link clicked: data from 'A' is copied to DB 'B' and 'A' is deleted. I have run similar processes with CSV output before and simply used //transfers old data to archive $transfer = mysql_query('INSERT INTO '.$archive.' SELECT * FROM '.$table) or die(mysql_error()); //empties existing table $query = mysql_query('TRUNCATE TABLE '.$table) or die(mysql_error()); but in those cases, ALL data returned was copied and deleted. I only want to copy and delete a single record. Any idea how to accomplish this?
