is there a limit to post_max_size?

1.) Is there a limit on post_max_size?
2.) How about upload_max_filesize?
3.) The manual mentioned something about memory_limit has to be bigger then post_max_size. I can't seem to find "memory_limit" in my phpinfo.php page. Am I blind?

your max upload size is set in php.ini, and it has to be smaller than the amount of ram your computer has available; that's typically no more than 50% of your total ram. why would you want to upload such mammoth files through php?

I was just curious.

Is there a way to error trap for post_max_size? Say a user uplaods 11 MB and my post_max_szie is set to 8MB. Right now all I get is a Can not find page error.

usually it is set in the form as max_file_size as a hidden input. that way you can check when the file gets uploaded.

by default php is set to 2M.

all you have to do is check the max_file_size against the filesize

something like this

$filesize=filesize($_FILES['fileupload']['name']);
if ($max_file_size!=0 and $filesize>$max_file_size) {
display to big message here.
}

Thanks

It's easy to change in php.ini. However, most people can't edit their php.ini (because their site is hosted and the hosting company won't allow it).

An easy way to get arround this if the following .htaccess file:
php_value post_max_size 1000M
php_value upload_max_filesize 1000M

Maybe this is a little bit off topic and obsolete for most of you PHP guru's, but I want to inform all other newbies (like me).

Good luck, Filip

Well, now that we're on the topic, could you tell me why this doesn't work for me? I use, the almost exact same, except they are in my virtual host, like so:



When i check my phpinfo page, it only uses one of the php_value directives, namely the upload_max_filesize and sets it neatly to 500M. But both upload_tmp_dir and post_max_size directives are not uploaded. Apache is restarted normally, without any hint in start up or in the logs.

If I use these same values in php.ini everything is fine, but in the Virtual Host, they don't work. I'm a little lost. Any ideas?
