在PHP中需要有关循环的帮助 [英] Need help on loop in PHP

问题描述

我有一个类似下面的for循环：

I have a for loop like bellow:

$a = array('a', 'b', 'c', 'd', 'e', 'g');
$b = array('1', '2');
$count_a = count($a); //count $a
$count_b = count($b); //count $b

$u = 0;
for($i = 0; $i < $count_a; $i++){
    $result[] = $a[$i].'-'.$b[$u];
    $u++;
    if($u == $count_b){
        print_r($result);
        $u = 0;
    }
}

结果：

And result for it:

Array
(
    [0] => a-1
    [1] => b-2
)
Array
(
    [0] => a-1
    [1] => b-2
    [2] => c-1
    [3] => d-2
)
Array

    [0] => a-1
    [1] => b-2
    [2] => c-1
    [3] => d-2
    [4] => e-1
    [5] => g-2
)

我希望结果如下：
