PHP script exiting before it is finished

Hi There

I have written a script for our website that imports listings into our database. The script does quite a bit of manipulating, importing listings, as well as pulling off and converting images from other sites (we have permission for all that).

However, my script always gets to around the 150 listing mark (no the same, sometimes 130's or more than 160) or in that range. I dont think it is a time limit on the script as I have set it quite high, and I also have another script written by someone else that runs alot longer but never quits prematurely.

Is there anything else other than time that could cause this premature exit, considering the code is good (when I restart the script it carries off from where it left off and goes for another 150 or so listings). Is it handling too much data? Is ther any way around this, i.e. clearing cache or letting it sleep for a while?

Thanks
Leon

Maybe increasing the memory limit helps? Are any error messages been shown? Do you have error_reporting on?

how do you run the script? is it as server side web script or as shell script? how to find it premature exit? is there error on your browser (assuming that you run the script as server side web script)? what is the error that you see?

Got error reporting on: error_reporting(E_ALL ^ E_NOTICE);

however it is not giving me any errors.

It is a server side web script. no errors, it just stops.

Two minutes, it seems to only run for 120 seconds and then stops.

Any idea why? Considering another script on our server runs for way longer.

leapingleonAuthor Commented:
Sorry, ignore last post, put a sleep function in and it went for longer.

It always seems to be about the 145 - 160 listing mark.

Ok, think I found out where it is always stopping, but still dont know why. It always seems to get to a certain part of the script, where I drag the images from another site to our server. Can you see anything wrong with the way I am doing it? Or, could it be that the memory is too high? Or too many open connections? Or anything, I really dont know.

every where you have return false,

I would place a debugging line like,

echo "1";

...

echo "2";

etc.

then see where it stops

It exits at different points all the time, but always during the following

$foo->Process('../../../Uploads/');

no, that's where you are calling and referencing the class, not where you actual written the class

class upload
{

}

$foo = new upload('image1.jpg'); //  << this upload class is what I want posted.

$foo = new upload('image1.jpg'); //Here's Where you create the upload class object

/**
 * Class upload
 *
 * <b>What does it do?</b>
 *
 * It manages file uploads for you. In short, it manages the uploaded file, 
 * and allows you to do whatever you want with the file, especially if it 
 * is an image, and as many times as you want.
 *
 * It is the ideal class to quickly integrate file upload in your site.
 * If the file is an image, you can convert, resize, crop it in many ways.
 * You can also apply filters, add borders, text, watermarks, etc...
 * That's all you need for a gallery script for instance. Supported formats
 * are PNG, JPG, GIF and BMP.
 *
 * You can also use the class to work on local files, which is especially
 * useful to use the image manipulation features.
 *
 * The class works with PHP 4 and 5, and its error messages can
 * be localized at will.
 *
 * <b>How does it work?</b>
 *
 * You instanciate the class with the $_FILES['my_field'] array
 * where my_field is the field name from your upload form.
 * The class will check if the original file has been uploaded
 * to its temporary location (alternatively, you can instanciate
 * the class with a local filename).
 *
 * You can then set a number of processing variables to act on the file.
 * For instance, you can rename the file, and if it is an image,
 * convert and resize it in many ways.
 * You can also set what will the class do if the file already exists.
 *
 * Then you call the function {@link process} to actually perform the actions
 * according to the processing parameters you set above.
 * It will create new instances of the original file,
 * so the original file remains the same between each process.
 * The file will be manipulated, and copied to the given location.
 * The processing variables will be reseted once it is done.
 *
 * You can repeat setting up a new set of processing variables,
 * and calling {@link process} again as many times as you want.
 * When you have finished, you can call {@link clean} to delete
 * the original uploaded file.
 *
 * If you don't set any processing parameters and call {@link process}
 * just after instanciating the class. The uploaded file will be simply
 * copied to the given location without any alteration or checks.
 *
 * Don't forget to add <i>enctype="multipart/form-data"</i> in your form
 * tag <form> if you want your form to upload the file.
 *
 * <b>How to use it?</b><br>
 * Create a simple HTML file, with a form such as:
 * <pre>
 * <form enctype="multipart/form-data" method="post" action="upload.php">
 *   <input type="file" size="32" name="image_field" value="">
 *   <input type="submit" name="Submit" value="upload">
 * </form>
 * </pre>
 * Create a file called upload.php:
 * <pre>
 *  $handle = new upload($_FILES['image_field']);
 *  if ($handle->uploaded) {
 *      $handle->file_new_name_body   = 'image_resized';
 *      $handle->image_resize         = true;
 *      $handle->image_x              = 100;
 *      $handle->image_ratio_y        = true;
 *      $handle->process('/home/user/files/');
 *      if ($handle->processed) {
 *          echo 'image resized';
 *          $handle->clean();
 *      } else {
 *          echo 'error : ' . $handle->error;
 *      }
 *  }
 * </pre>
 *
 * <b>How to process local files?</b><br>
 * Use the class as following, the rest being the same as above:
 * <pre>
 *  $handle = new upload('/home/user/myfile.jpg');
 * </pre>
 * 
 * <b>How to set the language?</b><br>
 * Instantiate the class with a second argument being the language code:
 * <pre>
 *  $handle = new upload($_FILES['image_field'], 'fr_FR');
 *  $handle = new upload('/home/user/myfile.jpg', 'fr_FR');
 * </pre>
 * 
 * <b>How to output the resulting file or picture directly to the browser?</b><br>
 * Simply call {@link process}() without an argument (or with null as first argument):
 * <pre>
 *  $handle = new upload($_FILES['image_field']);
 *  header('Content-type: ' . $handle->file_src_mime);
 *  echo $handle->Process();
 *  die();
 * </pre>
 * Or if you want to force the download of the file:
 * <pre>
 *  $handle = new upload($_FILES['image_field']);
 *  header('Content-type: ' . $handle->file_src_mime);
 *  header("Content-Disposition: attachment; filename=".rawurlencode($handle->file_src_name).";");
 *  echo $handle->Process();
 *  die();
 * </pre>
 *
 * <b>Processing parameters</b> (reseted after each process)
 * <ul>
 *  <li><b>file_new_name_body</b> replaces the name body (default: '')<br>
 *  <pre>$handle->file_new_name_body = 'new name';</pre></li>

 *
 * <b>Changelog</b>
 * <ul> 
 *  <li><b>v 0.25</b> 17/11/2007<br>
 *   - added translation files and mechanism to instantiate the class with a language different from English<br>
 *   - added {@link forbidden} to set an array of forbidden MIME types<br>
 *   - implemented support for simple wildcards in {@link allowed} and {@link forbidden}, such as image/*<br>
 *   - preset the file extension to the desired conversion format when converting an image<br>
 *   - added read and write support for BMP images<br>
 *   - added a flag {@link file_is_image} to determine if the file is a supported image type<br>
 *   - the class now provides some information about the image, before calling {@link process}(). Available are {@link image_src_x}, {@link image_src_y} and the newly introduced {@link image_src_bits}, {@link image_src_pixels} and {@link image_src_type}. Note that this will not work if <i>open_basedir</i> restrictions are in place<br>
 *   - improved logging; now provides useful system information<br>
 *   - added some more pre-processing checks for files that are images: {@link image_max_width}, {@link image_max_height}, {@link image_max_pixels}, {@link image_max_ratio}, {@link image_min_width}, {@link image_min_height}, {@link image_min_pixels} and {@link image_min_ratio}<br>
 *   - added {@link image_ratio_pixels} to resize an image to a number of pixels, keeping aspect ratio<br>
 *   - added {@link image_is_palette} and {@link image_is_transparent} and {@link image_transparent_color} for GIF images<br>

 *   - changed {@link image_background_color}, which now forces transparent areas to be painted<br>
 *   - improved reflections and color overlays so that it works with alpha transparent images<br>
 *   - {@link image_reflection_color} is now deprecated in favour of {@link image_default_color}<br />
 *   - transparent PNGs are now processed in true color, and fully preserving the alpha channel when doing merges<br>
 *   - transparent GIFs are now automatically detected. {@link preserve_transparency} is deprecated<br>
 *   - transparent true color images can be saved as GIF while retaining transparency, semi transparent areas being merged with {@link image_default_color}<br>
 *   - transparent true color images can be saved as JPG/BMP with the semi transparent areas being merged with {@link image_default_color}<br>
 *   - fixed conversion of images to true color<br>
 *   - the class can now output the uploaded files content as the return value of process() if the function is called with an empty or null argumenti, or no argument</li>
 *  <li><b>v 0.24</b> 25/05/2007<br>
 *   - added {@link image_background_color}, to set the default background color of an image<br>
 *   - added possibility of using replacement tokens in text labels<br>
 *   - changed default JPEG quality to 85<br>
 *   - fixed a small bug when using greyscale filter and associated filters<br>
 *   - added {@link image_ratio_fill} in order to fit an image within some dimensions and color the remaining space. Very similar to {@link image_ratio_crop}<br>
 *   - improved the recursive creation of directories<br>
 *   - the class now converts palette based images to true colors before doing graphic manipulations</li>
 *  <li><b>v 0.23</b> 23/12/2006<br>
 *   - fixed a bug when processing more than once the same uploaded file. If there is an open_basedir restriction, the class now creates a temporary file for the first call to process(). This file will be used for subsequent processes, and will be deleted upon calling clean()</li>
 *  <li><b>v 0.22</b> 16/12/2006<br>
 *   - added automatic creation of a temporary file if the upload directory is not within open_basedir<br>
 *   - fixed a bug which was preventing to work on a local file by overwriting it with its processed copy<br>
 *   - added MIME types video/x-ms-wmv and image/x-png and fixed PNG support for IE weird MIME types<br>
 *   - modified {@link image_ratio_crop} so it can accept one or more from string 'TBLR', determining which side of the image is kept while cropping<br>
 *   - added support for multiple lines in the text, using "\n" as a line break<br>
 *   - added {@link image_text_line_spacing} which allow to set the space between several lines of text<br>
 *   - added {@link image_text_alignment} which allow to set the alignment when text has several lines<br>
 *   - {@link image_text_font} can now be set to the path of a GDF font to load external fonts<br>

 *   - added {@link image_reflection_color} to set the reflection background color<br>
 *   - added {@link image_reflection_opacity} to set the initial level of opacity of the reflection</li>
 *  <li><b>v 0.21</b> 30/09/2006<br>
 *   - added {@link image_ratio_crop} which resizes within {@link image_x} and {@link image_y}, keeping ratio, but filling the space by cropping excedent of image<br>
 *   - added {@link mime_check}, which default is true, to set checks against {@link allowed} MIME list<br>
 *   - if MIME is empty, the class now triggers an error<br>
 *   - color #000000 is OK for {@link image_text_color}, and related text transparency bug fixed<br>
 *   - {@link gd_version}() now uses gd_info(), or else phpinfo()<br>

 *  <li><b>v 0.20</b> 11/08/2006<br>
 *   - added some more error checking and messages (GD presence, permissions...)<br>
 *   - fix when uploading files without extension<br>
 *   - changed values for {@link image_brightness} and {@link image_contrast} to be between -127 and 127<br>

     * This allows processing of a local file, as if the file was uploaded
