Solution in PHP (judge verdict: Accepted)

<?php
$w = trim(fgets(STDIN));
$w = strtolower($w);
$count = 0;
while (true) {
    $t = trim(fgets(STDIN));
    if ($t == 'END_OF_TEXT') {
        break;
     }
    $t = strtolower($t);
    foreach (explode(' ', $t) as $word) {
        if ($word == $w) {
            ++$count;
        }
    }
