数组中的字符串替换

Question

这是我对验证消息的回复

{"success":"0","message":{"Mobile":["The mobile field is required."],"DeviceId":["The device id field is required."]}}

我的代码在哪里

$Response = array('success' => '0', 'message' => $validation->messages());
return json_encode($Response);

我想删除所有[和]因此我的回复应为

{"success":"0","message":{"Mobile":"The mobile field is required.","DeviceId":"The device id field is required."}}

我尝试过

$err = str_replace("[", "", $validation->messages());
$error = str_replace("]", "", $err);
$Response = array('success' => '0', 'message' => $error);
return json_encode($Response);

我正进入（状态

{"success":"0","message":"{\"Mobile\":\"The mobile field is required.\",\"DeviceId\":\"The device id field is required.\"}"}

我什至尝试

$err = str_replace("[", " ", $validation->messages());

我该怎么做才能只删除[和]和[这样我的输出应该是

{"success":"0","message":{"Mobile":"The mobile field is required.","DeviceId":"The device id field is required."}}

Answer 1

您说的得到的与您说要得到的相匹配。 除此之外，\\“实际上只是PHP将”作为字符串一部分的方式。 如果您回应所得到的，那应该是您所寻找的。

Answer 2

尝试这个：

$obj = json_decode($validation->messages(), true);
foreach($obj as $k=>$v) $obj[$k] = $v[0];
$validation_messages = json_encode($obj);

Answer 3

$b = preg_replace('/\[|\]/', "", $validation->messages());
echo $b;
