Maximum file size that can be handles with a PHP script

[bizt]

Hi,

I am currently trying to debug a script written by my predecessor.
Basically I have an HTML form that is used to upload a file that is
then processed using a PHP script. It has been in frequent use but I
have just been contacted because there is a PDF document that is not
uploading.

I reckon it may have something to do with the file size. All the
previously uploaded files are relatively small (<2MB) but this one is
about 5MB. When I try to upload the file using the script, which I know
uploads the file as it has been in use frequently in the past and I
have tested it with other files, it appears to reject it. When I do the
following (before any processing when the form has been submitted):

echo $_FILES['file']['size'];

....it returns zero (0) indicating that something has gone wrong
although when I do the following:

echo $_FILES['file']['name'];

....it returns the name.

I have tried including a hidden HTML form element MAX_FILE_SIZE and
setting it to exceed the file size (in bytes) but still no luck. Could
it maybe be something in the files content?

Check your phpinfo();
post_max_size & upload_max_filesize

ini_set('post_max_size','16M');
ini_set('upload_max_filesize','16M')

However, some hosting providers do not allow you to change the post_max_size and upload_max_filesize!
Also, post_max_size should be bigger than upload_max_filesize, otherwise you will not be able to report the correct error in case of a too big upload !
Also check the max-execution-time (upload-time could be added to execution-time.

I all fails I suggest that you look at the 2-part Vince Barnes tutorial on uploading. The link to that tutorial is:
