Secure PHP with PHP's disable_functions?

Rand al'Thor · Jul 11, 2016

After installed a free hosting control panel, I was recommended to Secure PHP with PHP's disable_functions but they didn't show me guides

What are PHP's disable_functions and it can affect my site work normally?

It disables functions for security reasons. Yes turning of needed functions in php could cause a lot of problems.
Before you go changing anything you need to know exactly what you need to change. Check the documentation for the control panel.

Here's a guide

On your terminal, login to root account on your hosting

Code:

nano /etc/php.ini

Find disable_functions and set new list as following:

Code:

disable_functions =exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,parse_ini_file,show_source

I also recommend to disable allow_url_include and allow_url_fopen for security reasons:

Code:

allow_url_fopen=Off
allow_url_include=Off

Save and close the file. Restart the httpd server by tying the following command:

Code:

service httpd restart

The rest is you should follow LJSHost's advice
