What best practices should be followed when working with file contents and sorting data in PHP?
When working with file contents and sorting data in PHP, it is important to properly read the file, parse its contents, sort the data as needed, and then write the sorted data back to the file. One way to achieve this is by reading the file into an array, sorting the array using PHP's built-in sorting functions, and then writing the sorted array back to the file.
// Read the file into an array
$file_contents = file('data.txt', FILE_IGNORE_NEW_LINES);
// Sort the array
sort($file_contents);
// Write the sorted data back to the file
file_put_contents('data.txt', implode("\n", $file_contents));
