How to POST form data in PHP?

To post form data in PHP, you can use the built-in PHP Curl library. You need to initialize the PHP Curl library first by calling the curl_init() function. You can pass the target URL during initialization or set it later by calling the curl_setopt() function with the "CURLOPT_URL" parameter. To pass additional HTTP headers to a PHP POST HTML form request, you can call curl_setopt() with the "CURLOPT_HTTPHEADER" parameter. In this PHP Form POST example, we send the request header "Content-Type: application/x-www-form-urlencoded" to the server, which tells the server that the body of the POST request contains HTML form data.
