php - image creating slow down servre -

i have function , funqction i`m trying create images in server

           foreach($value[0] $imagekey => $imageval) {                 $imgname = $gancxadeba . '_' . $imagekey;                 $saveaddr = dirname(dirname($_server['php_self'])).'/www/classifieds_images/';                 $as = '.jpg';                 $originalname = $imgname . $as;                 if(!file_exists($saveaddr.$originalname)) {                     if (preg_match('/\.(jpg)$/', $imageval)) {                         $getfile = imagecreatefromjpeg($imageval);                     } elseif (preg_match('/\.(jpg)$/', $imageval)) {                         $getfile = imagecreatefromjpeg($imageval);                     } elseif (preg_match('/\.(png)$/', $imageval)) {                         $getfile = imagecreatefrompng($imageval);                     } else {                         $getfile = imagecreatefromgif($imageval);                     }                     list($width, $height) = getimagesize($imageval);                     $newwidth = 90;                     $newheight = 120;                     $original = imagecreatetruecolor($width, $height);                     imagecopyresampled($original, $getfile, 0, 0, 0, 0, $width, $height, $width, $height);                     imagejpeg($original, "../www/classifieds_images/$originalname");                     echo 'განცხადება: ' . $gancxadeba . ' ორიგინალი სურათი: ' . $imgname . ' created!' . php_eol;                      $thumbname = $imgname . '_thumb' . $as;                     if (!file_exists($saveaddr . $thumbname)) {                         $thumb = imagecreatetruecolor($newwidth, $newheight);                         imagecopyresampled($thumb, $getfile, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);                         imagejpeg($thumb, "../www/classifieds_images/$thumbname");                         echo 'განცხადება: ' . $gancxadeba . ' თამბი სურათი: ' . $imgname . ' created!' . php_eol;                     }                 }                 $image[$imagekey] = $imgname;             } 

as understand im getting image link , chacking if file exists , im creating file if not exists. server slow down. using 2gb ram. can accelerate server?

i tryed file_put_content() first , creating thumb not working gd library. please me function quicker is.

one thing note (not answer problem): when using gd2 functions, don't trust file extension. save jpeg name "trollpic.gif" , cause imagecreatefromgif throw error.

use exif data instead: http://php.net/manual/en/function.exif-imagetype.php

also - try imegemagick alternative gd2 if that's possible (it's not on cheaper hosting services).

[edit]

$original = imagecreatetruecolor($width, $height); imagecopyresampled($original, $getfile, 0, 0, 0, 0, $width, $height, $width, $height); imagejpeg($original, "../www/classifieds_images/$originalname"); 

looks $getfile , $original both keep same data. check if work:

$original = imagecreatetruecolor($width, $height); imagejpeg($getfile, "../www/classifieds_images/$originalname"); 

it's not best can optimize code, @ least it's start. i'd recommend setting limit how many files can processed in 1 execution of script , queueing - that's best if you're trying process lot of data, not image related.

also - unset variables when they're no longer needed. when you've done image , saved in file - destroy resource. won't remove image file, drop data memory. http://php.net/manual/en/function.imagedestroy.php
