Solution in PHP (judge verdict: Wrong Answer)

<?php
$pattern = strtolower(trim(fgets(STDIN)));
$count = 0;

while (true) {
  $text = explode(" ", strtolower(trim(fgets(STDIN))));
  if ($text[0] == "end_of_text") break;

  foreach ($text as $word)
    if ($word == $pattern) $count++;
}

echo $count . "\n";
