Fatal error: Allowed memory size of 31457280 bytes exhausted (tried to allocate 9828 bytes).

‘Fatal error: Allowed memory size of 31457280 bytes exhausted (tried to allocate 9828 bytes)’.

This is the error i get but I am only trying to upload a 1mb image. I have increased the memory limit in php.ini and the execution time. I am trying this on a local MAMP server, on a Mac using firefox. This going to be for an online image gallery. Any ideas? Below is the code:

    ini_set('memory_limit','30M');     if(isset($_POST['submit'])){       if (isset ($_FILES['new_image'])){           $imagename = $_FILES['new_image']['name'];           $source = $_FILES['new_image']['tmp_name'];           $target = 'images/'.$imagename;           move_uploaded_file($source, $target);            $imagepath = $imagename;           //below here for the removed code             $save = 'thumbs/uploads/' . $imagepath; //This is the new file you saving           $file = 'images/' . $imagepath; //This is the original file           $imagesize = getimagesize($file);            list($width, $height) = $imagesize;             unset($imagesize);            if($width>$height)             {                 $modwidth = 150;                  $diff = $width / $modwidth;                 $modheight = $height / $diff;             }else{                 $modheight = 150;                  $diff = $height / $modheight;                 $modwidth = $width / $diff;             }           $tn = imagecreatetruecolor($modwidth, $modheight);            $image = imagecreatefromjpeg($file);            $imagecopy = imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height);             imagedestroy($image);           imagedestroy($im);           imagedestroy($imagecopy);           imagedestroy($source);            $imagejpg = imagejpeg($tn, $save, 100);              imagedestroy($tn);           imagedestroy($imagejpg);

EDIT

This has now been sorted out hopefully. One of my colleagues had a solution all along but neglected to tell me!

  1. You’re likely loading the image to do some manipulation of it. That causes the image data to be decompressed, which requires a lot of memory for big images (I think it’s about 4 bytes per pixel).

    You can choose to either not process the image, or do your processing outside of PHP – for example by invoking ImageMagick or some other program. It depends a bit on what you’re trying to accomplish.
