PHP Fatal error: Out of memory (allocated 80740352) (tried to allocate 14592 bytes)

Hi guys,

Having a problem with users uploading photos onto my site. They can upload 6 images under 5MB. The memory setting is set to 128M in my php.ini and I doubled checked by phpinfo()

upload_max_filesize = 30M ;5MBlimit*6images=30MB
post_max_size = 30M
max_execution_time = 120
max_file_uploads = 7 
memory_limit=128M

However I get the error message occasionally:
PHP Fatal error: Out of memory (allocated 80740352) (tried to allocate 14592 bytes)

Something telling me it seems my memory_limit is not 128M but being capped at around 80M. Its an apache server. My code is like this NOTE - due to lenght I have cut out the error checks and only shown it for one image check out of the 6. But here it is but I cant see my code causing the problem as most people manage to upload there images:

if(move_uploaded_file($_FILES['uploadedfile_0']['tmp_name'], $move_file_to_directoryname_large))
{
        $n_width=100;$n_height=100; /*specify height/width of thumbnail image to be*/
                                                                                        
        if($_FILES["uploadedfile_0"]["type"]=="image/gif")
        {
                    $im=imagecreatefromgif($move_file_to_directoryname_large);
                    if(!$im)
                    {
                            /*error could occur here if image was say named .gif but was another type like .jpg casing file type error*/
                            $image_resize_error++; 
                            $array_error_msg_resize[$image_resize_error]="<p class='form_error_messages'>&#8226; An unfixable error occurred with your image ('<span class='standard_span'> " .$_FILES['uploadedfile_0']['name']." </span>').</p>";
                    }
                    else
                    {
                            $width=imagesx($im); $height=imagesy($im);

                            {

                            }
                            /*frees image from memory */
                            imagedestroy($newsmallerimage);

                            if(!$im)

                                            imagejpeg($newsmallerimage,$move_file_to_directoryname_small); 
                                            $images_db_small[0]=substr_replace($move_file_to_directoryname_small, "", 0, 24);
                                    }
                                    /*frees image from memory */
                                    imagedestroy($newsmallerimage);
                            }
                }
}

Any ideas? Would this be not a code problem but server problem not having enough RAM installed perhaps?

Thanks for assistance guys and girls

What line causes the error? 80MB of RAM should be fairly enough for a simple PHP script.

The line
$im=imagecreatefromjpeg($move_file_to_directoryname_large); line 31 above

is it your server, localhost,
or does the provider host/set the ram size regardless of your .ini settings
uploaded files = 5MB , undergoing manipulation = upto 5MB, output files if all are in memory at the same time could cause problems if the host set a lower memry limit
one of my hosts sets 1 1MB limit (but its SOOOOO cheap and very reliable), so use that one for all code and host images video etc on a different host where speed does not matter, the page is loaded and everything else can just dribble in

Well its not my server but the host said I can create my own custom php.ini file in public_html and it works so far, apart from this memory issue

[almostbob]

It may be a question to ask them,
if there is a memory limit, I'm pretty sure they dont plan on 121MB+ codespace for every user on a shared host, they may ask you to sequentially load and save the images to use less ram

Check the actual configurations being used with ini_get() function. That way you can be sure what is actually being used by PHP at runtime.
