What is the significance of backquotes in PHP Safe Mode?

In PHP Safe Mode, backquotes are disabled for security reasons as they allow execution of shell commands. To work around this limitation, you can use the `shell_exec()` function instead of backquotes to execute shell commands safely within PHP scripts. 

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