How can PHP developers efficiently read and process large files on a server using PHP?

When dealing with large files on a server, PHP developers can efficiently read and process them by using techniques like reading the file in chunks rather than loading it all into memory at once. This approach helps prevent memory exhaustion and allows for processing large files without performance issues. 

$filename = 'large_file.txt';
$handle = fopen($filename, 'r');
if ($handle) {
    while (($buffer = fgets($handle, 4096)) !== false) {
        // Process the current chunk of data
    }
    if (!feof($handle)) {
        echo "Error: unexpected fgets() fail\n";
    }
    fclose($handle);
}
