fatal error: allowed memory prob

[Chris-2k]

hi guys

im getting this prob:

Fatal error: Allowed memory size of 12582912 bytes exhausted (tried to allocate 5372 bytes)

when uploading a big image, it's pointed to this func:

PHP Code:

    function create_thumb($image_file, $name, $thumbDir) {
        $iDimension = getimagesize($image_file); 
        $type = $iDimension['mime'];
        $custom_px = $_POST['maxdimensions'];
        
        if ($type == "image/jpeg") { $tempThumb = imagecreatefromjpeg($image_file); }
        elseif ($type == "image/bmp") { $tempThumb = imagecreatefromwbmp($image_file); }
        elseif($type == "image/png") { $tempThumb = imagecreatefrompng($image_file); }
        elseif ($type == "image/gif") { $tempThumb = imagecreatefromgif($image_file); }

        $width = $iDimension[0]; // uploaded image width
        $height = $iDimension[1]; // uploaded image height
        
        $ratio = $width / $height; // calculate the ratio

        if ($ratio > 1 ) {
            $newW = $custom_px;
            $newH = $custom_px / $ratio;
        } else {
            $newH = $custom_px;
            $newW = $custom_px * $ratio;
        }
    
        $thumb = imagecreatetruecolor($newW, $newH);

        //the resizing is going on here!
        imagecopyresampled($thumb, $tempThumb, 0, 0, 0, 0, $newW, $newH, $width, $height);
    
        //finally, save the image
        imagejpeg($thumb, $thumbDir .'/thumb_' . $name);
        
        // clean up
        imagedestroy($thumb);
        imagedestroy($tempThumb);
    } 


any help, thanks.

The memory limit is set by the php.ini file, you can either increase the limit, not too likely unless it's your own server, or you can use a custom
php.ini file, or simply limit upload size to work within the assigned value.
