I have change upload_max_size to 300M while the post_max_size to 600M in php.ini. Now, I have made an upload script and try to upload some files. I've uploaded a file of about 100MB which is lower than my upload_max_size so i thought it would be ok. When I try to upload it i got this error message  "UPLOAD_ERR_INI_SIZE error".

Can anybody tell me what's with this error.

To upload larger files, the value of POST_MAX_SIZE must be larger than the upload_max_filesize. If limit of memory is enabled by your configure script, memory_limit also affects the file that is uploading. To be technical memory_limit should be larger than the post_max_size. When an integer value is used then the value is measured in bytes.

If the size of post data is greater than the post_max_size, the $_POST and $_FILES superglobalare is empty. This can be tracked in various ways for example by passing the $_GET variable to the script for processing the data, i.e. <form action="edit.php?processed=1">, and then by checking if $_GET[‘processed’] is set.

But you also check once that you have changed the required php.ini only. It sometimes happens that you change the other php.ini and then try to upload the file.
