What are the potential security risks involved in executing PHP scripts with elevated privileges using 'sudo' in a Raspberry Pi environment?

Executing PHP scripts with elevated privileges using 'sudo' in a Raspberry Pi environment can pose security risks as it grants the script more permissions than necessary, potentially allowing malicious actors to exploit vulnerabilities in the script to gain unauthorized access to the system. To mitigate this risk, it is recommended to carefully review the permissions required by the script and only grant the necessary privileges. 

<?php
// Check if the script is running with elevated privileges
if (posix_getuid() === 0) {
    // Log a warning message and exit
    error_log("Running PHP script with elevated privileges is not recommended.", 0);
    exit;
}

// Rest of the PHP script goes here
?>
