Are there any best practices for setting file permissions in PHP applications to avoid security risks?

Setting appropriate file permissions is crucial in PHP applications to avoid security risks. It is recommended to follow the principle of least privilege, where files and directories should only have the minimum necessary permissions for their intended use. This helps prevent unauthorized access and potential security breaches. 

// Set file permissions to 0644 for files and 0755 for directories
chmod('/path/to/file', 0644);
chmod('/path/to/directory', 0755);
