Taking a value from each line of a file to each their own var in php

Solution:

Use the file() function in PHP to split each line of the file into an array then set each element of the array equal to it’s respective variable. For example:

$lines = file('user1.txt');
$firstname = $lines[0];
$lname = $lines[1];
$age = $lines[2];
$gender = $lines[3];
