What is the best way to read each line of a text file in PHP?

When reading each line of a text file in PHP, the best way is to use the `fgets()` function within a loop to read each line until the end of the file is reached. This function reads a line from the file pointer and advances the file pointer to the next line. By using this method, you can efficiently process each line of the text file without loading the entire file into memory at once. 

$file = fopen('file.txt', 'r');

if ($file) {
    while (($line = fgets($file)) !== false) {
        // Process each line here
        echo $line;
    }
    fclose($file);
}
