How to modify the size limit of uploaded files in apache+php

When solving the PHP upload file size limit, not only PHP's upload file size limit must be modified, but Apache can also be modified.

System environment: centos 5.5

1. Modify the php file size limit vi /etc/php.ini Find: max_execution_time = 30, this is the maximum time for each script to run, in seconds, modify it to: max_execution_time = 150

Found: max_input_time = 60, this is the time that each script can consume, the unit is also seconds, modify it to: max_input_time = 300

Found: memory_limit = 128M. This is the maximum memory consumed by the script. Change the value according to the needs and modify it to: memory_limit = 256M

Found: post_max_size = 8M, the maximum data submitted by the form is 8M. This item does not limit the size of a single uploaded file, but limits the submitted data of the entire form. The scope of restrictions includes all content submitted in the form. For example: when publishing a post, the post title, content, attachments, etc., are modified to: post_max_size = 20M

Found: upload_max_filesize = 2M, the maximum allowed size of uploaded files, modified to: upload_max_filesize = 10M

2. Modify apache upload file size limit vi /etc/httpd/conf.d/php.conf LimitRequestBody 524288 changes 524288 (=512x1024) to a larger size, such as 5M (=5x1024x1024) The above problems will not occur when uploading. The upload does not respond. If the page cannot be uploaded, it will be solved!
