PHP CURL DELETE request

Question

I'm trying to do a DELETE http request using PHP and cURL.

I have read how to do it many places, but nothing seems to work for me.

This is how I do it:

public function curl_req($path,$json,$req) {     $ch = curl_init($this->__url.$path);     $data = json_encode($json);     curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $req);     curl_setopt($ch, CURLOPT_POSTFIELDS, $data);     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data)));     $result = curl_exec($ch);     $result = json_decode($result);     return $result; } 

I then go ahead and use my function:

public function deleteUser($extid) {     $path = "/rest/user/".$extid."/;token=".$this->__token;     $result = $this->curl_req($path,"","DELETE");     return $result;  } 

This gives me HTTP internal server ERROR. In my other functions using the same curl_req method with GET and POST, everything goes well.

So what am I doing wrong?

Answer 1

I finally solved this myself. If anyone else is having this problem, here is my solution:

I created a new method:

public function curl_del($path) {     $url = $this->__url.$path;     $ch = curl_init();     curl_setopt($ch, CURLOPT_URL, $url);     curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");     $result = curl_exec($ch);     $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);     curl_close($ch);      return $result; } 

Update 2

Since this seems to help some people, here is my final curl DELETE method, which returns the HTTP response in JSON decoded object:

  /**  * @desc    Do a DELETE request with cURL  *  * @param   string $path   path that goes after the URL fx. "/user/login"  * @param   array  $json   If you need to send some json with your request.  *                         For me delete requests are always blank  * @return  Obj    $result HTTP response from REST interface in JSON decoded.  */ public function curl_del($path, $json = '') {     $url = $this->__url.$path;     $ch = curl_init();     curl_setopt($ch, CURLOPT_URL, $url);     curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE");     curl_setopt($ch, CURLOPT_POSTFIELDS, $json);     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     $result = curl_exec($ch);     $result = json_decode($result);     curl_close($ch);      return $result; }

To call GET,POST,DELETE,PUT All kind of request, i have created one common function

function CallAPI($method, $api, $data) {     $url = "http://localhost:82/slimdemo/RESTAPI/" . $api;     $curl = curl_init($url);     curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);          switch ($method) {         case "GET":             curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));             curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "GET");             break;         case "POST":             curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));             curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "POST");             break;         case "PUT":             curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));             curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");             break;         case "DELETE":             curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "DELETE");              curl_setopt($curl, CURLOPT_POSTFIELDS, json_encode($data));             break;     }     $response = curl_exec($curl);     $data = json_decode($response);      /* Check for 404 (file not found). */     $httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);     // Check the HTTP Status code     switch ($httpCode) {         case 200:             $error_status = "200: Success";             return ($data);             break;         case 404:             $error_status = "404: API Not found";             break;         case 500:             $error_status = "500: servers replied with an error.";             break;         case 502:             $error_status = "502: servers may be down or being upgraded. Hopefully they'll be OK soon!";             break;         case 503:             $error_status = "503: service unavailable. Hopefully they'll be OK soon!";             break;         default:             $error_status = "Undocumented error: " . $httpCode . " : " . curl_error($curl);             break;     }     curl_close($curl);     echo $error_status;     die; } 

CALL Delete Method

$data = array('id'=>$_GET['did']); $result = CallAPI('DELETE', "DeleteCategory", $data); 

CALL Post Method

$data = array('title'=>$_POST['txtcategory'],'description'=>$_POST['txtdesc']); $result = CallAPI('POST', "InsertCategory", $data); 

CALL Get Method

$data = array('id'=>$_GET['eid']); $result = CallAPI('GET', "GetCategoryById", $data); 

CALL Put Method

$data = array('id'=>$_REQUEST['eid'],'title'=>$_REQUEST['txtcategory'],'description'=>$_REQUEST['txtdesc']); $result = CallAPI('POST', "UpdateCategory", $data);
