How can one efficiently read a .txt file line by line into an array in PHP?

When reading a .txt file line by line into an array in PHP, you can use the `file()` function to read the file into an array, with each line being an element in the array. This allows you to efficiently iterate over the lines of the file and process them as needed. 

$lines = file('file.txt', FILE_IGNORE_NEW_LINES);
foreach ($lines as $line) {
    // Process each line as needed
}
