How can permissions be managed for a PHP script on a shared hosting environment?

Permissions for a PHP script on a shared hosting environment can be managed by setting the correct file permissions for the script. This can be done by using the chmod function in PHP to set the appropriate permissions for the script file. It is important to set the permissions to restrict access to the script file to prevent unauthorized users from modifying or executing it.

// Set the correct file permissions for the PHP script file
$filename = 'script.php';
$permissions = 0644; // This sets the file permissions to allow read access for owner and group, and read access for others

if (!chmod($filename, $permissions)) {
    echo "Failed to set file permissions.";
} else {
    echo "File permissions set successfully.";
}
