Solution in PHP (judge verdict: Wrong Answer)

<?php
$array = array(0, 0, 0);
for ($i = 0; $i < 10; $i++) {
    $mountain = fscanf(STDIN, "%d", $data[$i]);
    if ($array[0] <= $mountain) {
        $array[2] = $array[1];
        $array[1] = $array[0];
        $array[0] = $mountain;
    } elseif ($array[1] <= $mountain) {
        $array[2] = $array[1];
        $array[1] = $mountain;
    } elseif ($array[2] <= $mountain) {
        $array[2] = $mountain;
    }
}
echo $array[0]."\n";
echo $array[1]."\n";
echo $array[2]."\n";
?>
