Enabling Specific PHP Functions

In PHP, certain functions are disabled by default for security reasons. To utilize these functions, you need to modify the disable_functions directive in the php.ini file. This guide will walk you through enabling the pcntl_signal and pcntl_alarm functions, which are commonly disabled.

Example before editing:

disable_functions = pcntl_alarm, pcntl_signal, exec, shell_exec

Example after editing:

disable_functions = exec, shell_exec
