You can't invoke a server side function (PHP) in a client side language (JavaScript).
However, you can emulate this by using AJAX and requesting an external webpage:
$("button").click(function () {
$(this).attr("disabled",true);
$.get("http://neil.computer/stack/test.php",function (data) {
$(document.body).html(data);
});
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<button>Load HTML!</button><?php
function myfun(){
echo "Hello World";
}
myfun();
?>
PHP is a server-side application so there, so you cannot directly call it onClick() because that event happens on the client side.
However, you can call it via JavaScript! More specifically aJax.
Here's a quick example from What is Sleep`s answer
AJax:
function callPHP() {
$.ajax ({
url: "yourPageName.php",
data: { action : assign }, //optional
success: function( result ) {
//do something after you receive the result
}
}
PHP:
if ($_POST["action"] == "assign")
{
assign(your parameters); //You need to put the parameters you want to pass in
//the data field of the ajax call, and use $_POST[]
//to get them
}
