POPHP Script stopping abruptly (imagecopyresampled)
text
Body
copied!<p>I have this script below that stops without an error after a certain amount of iterations. When the images it is using are ~4MB, the script stops after about 10 iterations. When the images are around 1MB, the script stops after ~30 iterations. When the images are smaller, the script can go for 500 iterations. It doesn't seem to be a timeout, as it happens at a different time count each time.</p> <p>When I test this on my own machine using xxamp, there are no errors, and the script finishes perfectly.</p> <p>I am guessing this is some type of memory problem? I am completely inexperienced and clueless when it comes to memory.</p> <p>EDIT: I put an echo before the imagecopyresampled function and after. The script seems to stop on this function.</p> <p>Here is my loop that goes through each file in the directory:</p> <pre><code>while (false !== ($filer = readdir($handle))) { if (is_file($srcDir . '/' . $filer)) { set_time_limit(20); $counter++; $total = $x; $percent = intval($counter/$total * 100)."%"; // Javascript for updating the progress bar and information echo '<script language="javascript"> document.getElementById("progress").innerHTML="<div style=\"width:'.$percent.';background-color:#333;\">&nbsp;</div>"; document.getElementById("information").innerHTML="'.$counter.' images processed."; </script>'; //location/filename variable $filename = $srcDir . '/' . $filer; // This is for the buffer achieve the minimum size in order to flush data echo str_repeat(' ',1024*64); // Send output to browser immediately flush(); //get the extension of the image $path_parts = pathinfo("$filename"); $ext = strtolower ($path_parts['extension']); $width = 100; $height = 100; // Get new dimensions list($width_orig, $height_orig) = getimagesize($filename); $ratio_orig = $width_orig/$height_orig; if ($width/$height > $ratio_orig) { $width = $height*$ratio_orig; } else { $height = $width/$ratio_orig; } // Resample $image_p = imagecreatetruecolor($width, $height); $image = imagecreatefromjpeg($filename); imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig); // Output the small image imagejpeg($image_p, "$destDir/$filer", 100); //Move the big image rename($srcDir . '/' . $filer, $destDirbig . '/' . $filer); echo $counter; } } </code></pre>
