怎么把这字符串变成数组,用implode没有用,应该怎么变成数组呢

提交多张图片后。我把图片的$_FILES打印出来,进行foreach循环,如果没有报错的,打印出图片的$key值,我想把$key变成一个数组。
foreach($_FILES as $key=>$value){
if(!$value['error']){

print_r($key);
}}

然后用implode没有效果

var_dump一下,是三个字符串

根据你评论下面的要求,写了这个观点,你看是否符合你的要求
$res = array();
foreach($_FILES as $key=>$value){
if(!$value['error']){
     $res[]= array($key=>$value['tmp_name']);  
}}
$res = array_values($res);
print_r($res);
