How can i call function from php file when the icon clicked

Answer 1

A jquery demo is as follows:-

abc.php:- (you can change extension to .html also if you are not going to use any php code in this file)

<button class="fa fa-angle-right" onclick="myFunction();">Click Me Please!</button>

<script src= "https://code.jquery.com/jquery-3.1.1.min.js"></script>

<script type="text/javascript">
function myFunction(){

     $.ajax({url: "demo_test.php", success: function(result){
        alert(result);
    }});
}
</script>

demo_test.php:-

<?php
include_once('def.php');

$obj = new myClass();

$result = $obj->method1();

echo $result;
?>

def.php:-

<?php
class myClass{
    function method1(){
        echo "demo";
    }
    function method2(){
        echo "demo2";
    }
}

Output:- http://prntscr.com/clw7hu and http://prntscr.com/clw7sl

Note:-

All three files must be at same working location(same directory)

It's a very small and easy sample to understand what is exactly need and how it can performed. Thanks
