Core PHP: Reading a File (8.5)

Reading a File

The file() function reads the entire file into an array. Each element within the array corresponds to a line in the file:

$read = file('names.txt');
foreach ($read as $line) {
  echo $line .", ";
}

This prints all of the lines in the file, and separates them with commas.

We used the foreach loop, because the $read variable is an array.
