Error loading really big file in PHP?

Question

I have a PHP form for uploading files, and it works fine and displays an error message if something went wrong. This is all good.

The problem is that when I test with a really large file, it just refreshes the page, as if I hadn’t sent the file at all, and not one of the $ _POST variables from the form was even sent to the server.

I want to show the user an error by telling them that the file is too large. However, I cannot do this.

Does anyone know what is going on?

Answer 1

Check your PHP ini file, which determines how large the PHP file will allow to load. These variables are important:

• max upload filesize (upload_max_filesize)
• (post_max_size)
• (memory_limit)
