I am trying to load this file which has an array of strings but when I load it it doesn't separate the the values... what am I doing wrong?

codes1.txt

["foo","bar","biz"]

test.php

<?php
  error_reporting(E_ALL);
  ini_set('display_errors', 1);

  $contents = array(file("codes1.txt"));


  foreach ($contents as $value) {
    echo $value;
    echo "<p>test</p>";
  }
?>
