What are best practices for managing file permissions in PHP scripts during installation?

When installing PHP scripts, it is important to properly manage file permissions to ensure security and functionality. One best practice is to set appropriate permissions for directories and files, such as limiting write access to only necessary files and directories. Additionally, using PHP functions like `chmod()` can help set permissions programmatically during installation. 

// Set appropriate permissions for directories and files
chmod('/path/to/directory', 0755); // Example: set directory permission to 755
chmod('/path/to/file.php', 0644); // Example: set file permission to 644
