JavaScript c9 - How to run php function from script tag? function from script powershell,call function from script matlab,import

I use cloud 9 platform. I have php file with several functions call phpFunctions.php:

<?php
 $servername = "127.0.0.1";
 $username = "oshrat";
 $password = "";
 $database = "myDB";
 $dbport = 3306;

// Create connection
//$conn = new mysqli($servername, $username, $password);
$conn = new mysqli($servername, $username, $password, $database, $dbport);

// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
} 
// echo "Connected successfully";
mysql_select_db("myDB",$conn);

function createNewUser() {
 echo "Hello world!";
}

function checkUser($name) {
 echo "Hello world!";
}
?>

From the form I have a button and when the onclick event occurs, I need to run the function checkUser.

login.php file:

<html lang="en-us">

<head>
<meta charset="utf-8">
<?php include_once 'phpFunctions.php';?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js">    </script>
</head>

<body>
<div  style="float:left; margin-right:45px;">            
    <button id="startButton" class="controlButtons" type="button"     target="framework" style="margin-left:30vw;">Go To Play</button>
</div>
</body>
<script type="text/javascript">
     $("#startButton").click(function(){
        var p1Name = $("#namePlayer1").val();
        var p2Name = $("#namePlayer2").val();
        //check if the two players enter the name
        if(p1Name == "" || p2Name == "")
        {
            alert("You Must Enter Two Players Name");
        }
            else 
            {
            var result = "";
            jQuery.ajax({
                type: "POST",
                url: 'phpFunctions.php',
                dataType: 'json',
                data: {functionname: 'checkUser'},
        success: function (obj, textstatus) {
                if( !('error' in obj) ) {
                            //   result = obj.result;
                              alert("success");
                          }
                          else {
                            //   console.log(obj.error);
                            alert("error");
                          }
                    }
        });
                   }
    }
});

    </script>
</html>

The ajax call is not working. Thank you in advance for your help.
