How does SafeMode in PHP affect the execution of certain functions like exec()?

SafeMode in PHP restricts certain functions like exec() for security reasons. To work around this limitation, you can use alternative functions like shell_exec() which are not affected by SafeMode. By using shell_exec() instead of exec(), you can still execute shell commands in a safe manner without being blocked by SafeMode. 

$output = shell_exec('ls -l');
echo "<pre>$output</pre>";
