How to modify the upload file size limit using php

This article mainly introduces how to use php to modify the size limit of uploaded files. It has certain reference value. Now I share it with you. Friends in need can refer to it.

By default, php only Files of a certain size are allowed to be uploaded. When the uploaded file size exceeds this value, an error will occur. This article will explain to you how to modify the upload file size limit in php.ini. There are three settings that need to be modified, please see below

1. Modify max_execution_time

In php, the default maximum page execution time is 30 seconds, if it exceeds 30 seconds, the script will stop executing.
In this case, the web page will not be opened. At this time, we can modify max_execution_time
Look for it in php.ini

max_execution_time

The default is 30 seconds. Change to

max_execution_time = 0

0 means no limit

2. Modify post_max_size

post_max_size sets the maximum size allowed for POST data. This setting also affects file uploads.
The default post_max_size of php is 2M. If the POST data size is larger than post_max_size $_POST and $_FILES superglobals will be empty.
Look for post_max_size and change it to

post_max_size = 150M

3. Modify upload_max_filesize

upload_max_filesize indicates the maximum size of the uploaded file.

Look for upload_max_filesize, the default is 8M and change it to

Another thing to note is that post_max_size is greater than upload_max_filesize Best.
