What are common issues with setting directory permissions using PHP scripts?

Common issues with setting directory permissions using PHP scripts include incorrect file paths, insufficient permissions, and improper syntax for setting permissions. To solve this, ensure that the file paths are correct, the script has the necessary permissions to modify the directory, and the syntax for setting permissions is accurate. 

<?php
$directory = '/path/to/directory';
$permissions = 0755; // Example: read, write, execute for owner, read and execute for group and others

if(is_dir($directory)){
    chmod($directory, $permissions);
    echo "Permissions set successfully for directory: $directory";
} else {
    echo "Directory does not exist";
}
?>
