Question

我有2个阵列

Array
(
    [0] => bedroom
    [1] => traditional
    [2] => farmhouse
    [3] => modern
    [4] => contemporary
)

和

Array
(
    [0] => aaaa
    [1] => bbbb
    [2] => cccc
    [3] => dddd
    [4] => eeee
    )

如何组合上面的两个数组，我希望结果像 String 一样......

bedroom_aaaa, traditional_bbbb, farmhouse_cccc, modern_dddd, contemporary_eee

到目前为止，我尝试过这样，但它不起作用......

$res = array_combine ($a,$b);

                foreach($res as $r){
                  echo $res.'_'.$r.', ';
                }

Answer 1

从你的逻辑中我找到了方法......谢谢

        if(count($a)==count($b)){
            for($i=0;$i<count($a);$i++){
                $res = $a[$i]." _ ".$b[$i];
                echo $res.'<br />';
            }
        }

Answer 2

这个php函数将两个数组作为输入，并检查它们是否具有相同的大小。如果两个阵列的大小不同，则会出现错误＆＃34;未定义的索引＆＃34;。
