It's easy to create web service in php.

First create one php file in your website folder like "firstwebservice.php".
and open this file in any text editor.

Now copy this code and past in file.

<?php
//add header for json
header("Content-Type:application/json");

//if you send url paramers
if(!empty($_REQUEST))
    {
        //url parameter "param"
        if(isset($_REQUEST["param"]))
        {
            try
            {
                $param=$_REQUEST['param'];  
              
                $response['status'] = 200;
                $response['param'] = $param;
              
                //return output as json format
                echo json_encode($response);
            }
            catch(Exception $ex)
            {
                $error = array(
                    "status"=> 500,
                    "message"=>".$ex->getMessage()."
                );
                echo json_encode($error);
