Solution in PHP (judge verdict: Wrong Answer)

<?php
    $math_ary = array();
    $tmp;
    while($line = trim(fgets(STDIN))){
        $math_ary[] = $line;
    }
    for($i = 0;$i < count($math_ary)-1;$i++){
        for($j = $i;$j < count($math_ary);$j++){
            if($math_ary[$i] > $math_ary[$j]){
                $tmp = $math_ary[$i];
                $math_ary[$i] = $math_ary[$j];
                $math_ary[$j] = $tmp;
            }
        }
