2.8.20. Disable PHP functions
When a disabled function is called in a script, a warning E_WARNING is returned. Execution of the script is not terminated in this case.
The disable_functions parameter allows you to disable only PHP built-in functions; it does not affect user-defined functions. For example, you can use it to prevent site scripts from sending mail using the mail function, or to enhance security by blocking the use of functions such as exec and shell_exec.
- Open the "Hosting → My sites → your site → PHP settings" section.
- In the "disable_functions" field, enter the names of the functions you want to disable, separated by commas, and save your changes:
- Wait 10-15 minutes for the changes to take effect.
To re-enable disabled features, remove them from the list, save your settings, and wait for the changes to take effect.
