Ajax 解析错误。 Ajax 成功后返回错误。 Php 工作正常，但响应仍然错误

Question

Ajax 解析错误。 Ajax 成功后返回错误。 PHP 工作正常，但响应仍然出错。 该代码适用于 curl 但不适用于 xml。 I'm not a pro in xml but the API return xml response so I am forced to use xml I can't identify the error SMS is being sent and database is successfully updated but the ajax is not properly working. 希望我已经解释得够多了

这是发送表单数据的 ajax 代码

$.ajax({
                                                                
data:$('form#candidateForm').serialize(),
type:"POST",
url:"php-modules/registeration.php",
success:function(msg){
alert(typeof msg);
if(typeof msg =='object'){
$("#otpc_id").val(msg.c_id);
jQuery('.careerfy-modal').removeClass('fade-in').addClass('fade');                                                                       jQuery('body').removeClass('careerfy-modal-active');                                                                         jobsearch_modal_popup_open("otpVerification");
}
else{
alert(msg);
}     
},
error: function(request, error){
console.log(arguments);
alert(" Can't do because: " + error);
alert("Error connecting to file");
 }
 });

php 向数据库中插入数据成功后发送otp消息并返回xml响应的代码

//OTP SMS Variables 
               $message='Your OTP Code '.$rand_no.'.';

               // OTP FUNCTION
               $sessionKey=getSessionId();
               $ph_number=$GLOBALS['c_phone'];
               $phone = preg_replace('/[^\dxX]/', '', $ph_number);

               $send = sendSmsMessage($message,$phone,'OEC-GoP',$sessionKey );
               //echo "1";
               //IF SUCCESSFULLY MESSAGE IS SENT 
               if($send){
                echo $send;
                $candidate_id = array("c_id"=>"$last_id");
                header("Content-Type: application/json");
                echo json_encode($candidate_id);
               }else{
                echo "measageNotSent";
               }

xml代码

function sendSmsMessage($messageText,$toNumbersCsv,$mask,$sessionKey)
{
global $planetbeyondApiSendSmsUrl;
$sessionKey=getSessionId();
$url=str_replace("#message_text#",urlencode($messageText),$planetbeyondApiSendSmsUrl);
$url=str_replace("#to_number_csv#",$toNumbersCsv,$url);
$url=str_replace("#from_number#",$fromNumber,$url);
$urlWithSessionKey=str_replace("#session_id#",$sessionKey,$url);
if($mask!=null)
{
$urlWithSessionKey = $urlWithSessionKey . "&mask=" . $mask;
}
$xml=sendApiCall($urlWithSessionKey);
return $xml->data;
}
/**
 Sends Http request to api
*/
function sendApiCall($url)
{
$response = file_get_contents($url);
$xml=simplexml_load_string($response) or die("Error: Cannot create object");

 if($xml && !empty($xml->response))
 {
return $xml;
}
return "";
}
function getSessionId()
{
global $userName,$password,$planetbeyondApiUrl;
$url=str_replace("#username#",$userName,$planetbeyondApiUrl);
$url=str_replace("#password#",$password,$url);
$response = sendApiCall ($url);
 if($response && substr($response->response,0,5)!=="Error")
 {
return $response->data;
}
return -1;
}

由于未设置 fromNumber 变量而发生错误。 因此，php 使用 Json 代码附加了错误，删除了额外的代码行，代码运行正常。 // $url=str_replace("#from_number#",$fromNumber,$url);
