比较这两个排序算法，实现有序数组的重新排序

1 . 定义$a,$b两个指针

2 . 使用php的内置函数

$array_a = array(2,5,7);
    $array_b = array(1,2,3,8,9);
    $length_a = count($array_a);
    $length_b = count($array_b);
    $array_c = array();
    $a = 0;
    $b = 0;
    $time_a = microtime(true);
    while(true){
        if($a == $length_a || $b == $length_b)
            break;
        if($array_a[$a] $array_b[$b]){
            $array_c[] = $array_a[$a];
            ++$a;
        }else{
            $array_c[] = $array_b[$b];
            ++$b;
        }
    }
    if($a == $length_a){
        while($b $length_b){
            $array_c[] = $array_b[$b++];
        }
    }
    else{
        while($a $length_a
