Php curl post request8/15/2023 ![]() ![]() Make sure to put this code into a file or place that can be accessed by your entire app or website. This is why I’ve created a ‘simple’ PHP script that allows us to call this function, with a set of parameters, and a cURL request will be done. Implementing an external API into your project is probably going to take more than just one API call and from different pages in your project. If you’re looking for a simple cURL GET function to retrieve your API data with PHP, please check if my basic cURL API connection with PHP is a better fit for your needs. Now that we understand the basics, let’s try to put this into a function we can reuse within our application. So after we did our call and closed the connection, we can still access the result using our $output variable. This $output variable is still available in our program even after we closed it with curl_close(). Note that we stored our curl_exec() in a variable $output. (deletes the variable made by curl_init) close curl resource to free up system resources curl_exec() executes the started curl session return the transfer as a string, also with setopt()Ĭurl_setopt($curl, CURLOPT_RETURNTRANSFER, 1) create & initialize a curl sessionĬurl_setopt($curl, CURLOPT_URL, "") The request will return the API response as a string. Before we start with the article and our cURL setup, I’ve added a simple example of a plain cURL request. I’ve received a lot of responses on ‘how does cURL actually work’ and I get the feeling that people don’t know what’s going on in a cURL call. ![]() This article will provide more in-depth examples for integrating your applications. More info about how cURL actually works can be found in the official PHP documentation. $mixResponse contains your server response.CURL stands for ‘Client URL Library’ and it allows you to connect and communicate with different types of servers with many different types of protocols (HTTP, https, FTP, proxy, cookies, …). If HTTP authentication is required, use the below lines.ĬURLOPT_USERPWD => $username. 'Content-Type: application/json', // Only USE this when requesting JSON data $postData = json_encode($arrPostData) // Only USE this when request JSON data. $postData = http_build_query($arrPostData) // Raw PHP array $requestType = 'POST' // This can be PUT or POST I hope this will help others save their time.Ĭurl_setopt($mixCH, $strCurlOpt, $mixCurlOptValue) $data = array('name' => 'Ross', 'php_master' => true) Ĭurl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data)) ![]() $data as url encoded string: The data will be sent as application/x-www-form-urlencoded, which is the default encoding for submitted html form data. ![]() $data = array('name' => 'Ross', 'php_master' => true) $data as an array(): The data will be sent as multipart/form-data which is not always accepted by the server. It is important to note that curl_setopt($handle, CURLOPT_POSTFIELDS, $data) takes the $data in two formats, and that this determines how the post data will be encoded. This can be used to submit data to POST s. We have two options here, CURLOPT_POST which turns HTTP POST on, and CURLOPT_POSTFIELDS which contains an array of our post data to submit. You can POST a file by prefixing with an (for fields)Ĭurl_setopt($handle, CURLOPT_POST, true) Ĭurl_setopt($handle, CURLOPT_POSTFIELDS, $data) ![]()
