What are the best practices for handling file permissions and file creation in PHP scripts on a private server environment?

When handling file permissions and file creation in PHP scripts on a private server environment, it is important to ensure that files are created with the appropriate permissions to maintain security and prevent unauthorized access. One best practice is to set the correct permissions when creating a new file using the `fopen()` function in PHP. Additionally, it is recommended to use the `chmod()` function to explicitly set the permissions on the file after creation. 

// Create a new file with specific permissions
$filename = 'newfile.txt';
$file = fopen($filename, 'w');
fclose($file);

// Set the file permissions to 0644 (read/write for owner, read for group and others)
chmod($filename, 0644);
