Sometime we need to work with web services and APIs of third party website, at that time we need to use php curl for get request, post request, delete request, put request ect. php curl will help to post request with parameters and headers, we can get json response.

PHP cURL have set of curl function like curl_init(), curl_setopt(), curl_exec() etc. using cURL we will call apis to getting json data and we can use their data in our project.

Here, i will give you very simple example of curl request and also give you headers with authentication example on bellow of simple curl request example:

Simple Example:

/* API URL */
$url = 'http://www.mysite.com/api';
  
/* Init cURL resource */
$ch = curl_init($url);
  
/* Array Parameter Data */
$data = ['name'=>'Hardik', 'email'=>'itsolutionstuff@gmail.com'];
  
/* pass encoded JSON string to the POST fields */
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
  
/* set the content type json */
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
  
/* set return type json */
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  
/* execute request */
$result = curl_exec($ch);
