现在输出的结果是

["1","2","3","4"]

Answer 1

这样可以解决你的问题吗？将现在的输出结果用下面的函数在处理一下，将返回你要的结果。

function handle($array){
        $str = ''; $arr = [];
        foreach ($array as $key => $value){
            $num = $key + 1;
            $str .= $value.'='.$num.' ';
            $arr[] = (string)$num;
        }
        return [$str, $arr];
    }

使用方法

$arr = ["a","b","c","d"];
$result = handle($arr);

print_r($result[0]);
print("<br />");
print_r($result[1]);

输出结果
a=1 b=2 c=3 d=4
Array ( [0] => “1” [1] => “2” [2] => “3” [3] => "4" )
