What are common issues with setting folder permissions in PHP scripts?

Common issues with setting folder permissions in PHP scripts include not having the proper permissions to change the folder permissions, incorrect syntax in the chmod function, and setting overly permissive permissions that may pose security risks. To solve these issues, ensure that you have the necessary permissions to modify the folder permissions, double-check the syntax of the chmod function, and set permissions to the minimum required for the functionality of your script. 

// Set folder permissions to 755
$folder = '/path/to/folder';
if (is_dir($folder)) {
    chmod($folder, 0755);
    echo "Folder permissions set to 755 successfully";
} else {
    echo "Folder not found";
}
