Solution in PHP (judge verdict: Wrong Answer)

<?php

fscanf(STDIN, '%s', $W);

$W = strtolower($W);
$cnt = 0;

while (($line = trim(fgets(STDIN))) !== '') {
    if ($line === 'END_OF_TEXT') {
        break;
    }

    $line = strtolower($line);
    $cnt += substr_count($line, $W);
}

echo $cnt, PHP_EOL;
