What are the correct file permissions needed for PHP scripts to write to files on a server?

PHP scripts need to have the correct file permissions in order to write to files on a server. Typically, the file or directory that the PHP script is trying to write to should have the correct permissions set to allow the PHP process to write to it. The recommended permissions for files are usually 644 and for directories are usually 755. 

// Set the correct file permissions for writing to a file
$file = 'path/to/file.txt';

// Set the correct permissions for the file
chmod($file, 0644);

// Write to the file
file_put_contents($file, 'Hello, World!');
