Curl and PHP - how can I pass a json through curl by PUT,POST,GET

Question

I have been working on building an Rest API for the hell of it and I have been testing it out as I go along by using curl from the command line which is very easy for CRUD

I can successfully make these call from the command line

curl -u username:pass -X GET http://api.mysite.com/pet/1 curl -d '{"dog":"tall"}' -u username:pass -X GET http://api.mysite.com/pet curl -d '{"dog":"short"}' -u username:pass -X POST http://api.mysite.com/pet curl -d '{"dog":"tall"}' -u username:pass -X PUT http://api.mysite.com/pet/1 

The above calls are easy to make from the command line and work fine with my api, but now I want to use PHP to create the curl. As you can see, I pass data as a json string. I have read around and I think I can probably do the POST and include the POST fields, but I have not been able to find out how to pass http body data with GET. Everything I see says you must attached it to the url, but it doesn't look that way on the command line form. Any way, I would love it if someone could write the correct way to do these four operations in PHP here on one page. I would like to see the simplest way to do it with curl and php. I think I need to pass everything through the http body because my php api catching everything with php://input

PUT

$data = array('username'=>'dog','password'=>'tall'); $data_json = json_encode($data);  $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json','Content-Length: ' . strlen($data_json))); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT'); curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response  = curl_exec($ch); curl_close($ch); 

POST

$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json')); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response  = curl_exec($ch); curl_close($ch); 

GET See @Dan H answer

DELETE

$ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "DELETE"); curl_setopt($ch, CURLOPT_POSTFIELDS,$data_json); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $response  = curl_exec($ch); curl_close($ch); 

Answer 2

You can use this small library: https://github.com/ledfusion/php-rest-curl

Making a call is as simple as:

// GET $result = RestCurl::get($URL, array('id' => 12345678));  // POST $result = RestCurl::post($URL, array('name' => 'John'));  // PUT $result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));  // DELETE $result = RestCurl::delete($URL);  

And for the $result variable:

• $result['status'] is the HTTP response code
• $result['data'] an array with the JSON response parsed
• $result['header'] a string with the response headers

Hope it helps
