What role does the safe mode setting play in PHP file operations on Debian?

Safe mode in PHP restricts certain file operations for security reasons, such as preventing scripts from accessing files outside of the designated directories. To work around this limitation in Debian, you can modify the open_basedir directive in your php.ini configuration file to specify the allowed directories for file operations. 

// Set the allowed directories for file operations
ini_set('open_basedir', '/path/to/allowed/directory:/another/allowed/directory');

// Perform file operations within the allowed directories
$file = '/path/to/allowed/directory/example.txt';
$handle = fopen($file, 'r');
$data = fread($handle, filesize($file));
fclose($handle);
