Solution in PHP (judge verdict: Wrong Answer)

<?php
  $str = trim(fgets(STDIN));
  $result = "";
  while (true) {
    $ary = trim(fgets(STDIN));
    $result += (" " . $ary . " ");
    if ($ary == "END_OF_TEXT") {
      print(substr_count(strtolower($result), (' ' . strtolower($str) . ' ')));
      return;
    }
