[php] POST Content-Length exceeds the limit

I get similar errors in my error_log in php when users are uploading their files

PHP Warning: POST Content-Length of 11933650 bytes exceeds the limit of 8388608 bytes in Unknown on line 0

In my php.ini (created custom ini file in public_html) would this solve this problem, how much would I have to set it to around 1GB? I am going to change my settings to this in php.ini, will it solve the problem?

upload_max_filesize = 1000M ;1GB
post_max_size = 1000M

What would I set the 'memory_limit' limit to.

Also would this be correct in my script to check file uploaded size is <1GB

if($_FILES["uploadedfile"]["size"]<1000000)

This question is related to php

The answer is


Try pasting this to .htaccess and it should work.

php_value post_max_size 2000M
php_value upload_max_filesize 2500M
php_value max_execution_time 6000000
php_value max_input_time 6000000
php_value memory_limit 2500M

In Some cases, you need to increase the maximum execution time.

max_execution_time=30

I made it

max_execution_time=600000

then I was happy.


I suggest that you should change to post_max_size from 8M to 32M in the php.ini file.


If you are using Php 5.6.X versions in windows using Wamp, then file location may be in,

C:\Windows\php.ini

Just try with

post_max_size = 100M;

Try to do changes in Apache one. By that your Wamp/XAMP load .ini file


There might be more than just one php.ini file. For example, when using WAMP there are 2 php.ini files in following directories:

  • C:\wamp\bin\apache\apache2.4.9\bin
  • C:\wamp\bin\php\php5.5.12

You need to edit the first one.


post_max_size should be slightly bigger than upload_max_filesize, because when uploading using HTTP POST method the text also includes headers with file size and name, etc.

If you want to successfully uppload 1GiB files, you have to set:

upload_max_filesize = 1024M
post_max_size = 1025M

Note, the correct suffix for GB is G, i.e. upload_max_filesize = 1G.

No need to set memory_limit.


you just setting at php.ini

then set :

upload_max_filesize = 1000M;
post_max_size = 1000M;

then restart your xampp.. Check the image


I disagree, but the solution to increase the file size in php.ini or .htaccess won't work if the user sends a file larger than allowed by the server application.

I suggest validating this on the front end. For example:

_x000D_
_x000D_
$(document).ready(function() {
    $ ('#your_input_file_id').bind('change', function() {
        var fileSize = this.files[0].size/1024/1024;
        if (fileSize > 2) { // 2M
            alert('Your custom message for max file size exceeded');
            $('#your_input_file_id').val('');
        }
    });
});
_x000D_
_x000D_
_x000D_
