Sending POST API Request [PHP Code]

To make a POST request to an API endpoint using PHP, you need to send an HTTP POST request to the server and specify a Content-Type request header that specifies the data media type in the body of the POST API request. The Content-Length header indicates the data size in the POST message body. In this PHP POST API Request example, we send a POST request to the ReqBin echo API URL.
