When working with large text files in PHP, what are some best practices for efficiently sorting and processing the data?

When working with large text files in PHP, it is important to efficiently sort and process the data to prevent memory issues and improve performance. One way to achieve this is by reading the file line by line instead of loading the entire file into memory at once. Additionally, using functions like `fgets()` or `fgetcsv()` can help in processing the data efficiently. 

$filename = 'large_text_file.txt';
$handle = fopen($filename, 'r');

if ($handle) {
    while (($line = fgets($handle)) !== false) {
        // Process each line of the file here
    }

    fclose($handle);
} else {
    echo "Error opening the file.";
}
