Can html trigger php functions?

html cannot trigger php functions. HTML is a hypertext markup language, which is only used to build the page structure. It cannot trigger a certain function of php.

To trigger a certain function of PHP, we have the following implementation methods:

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
       if (this.readyState == 4 && this.status == 200) {
           console.log(this.responseText)
       }
};
xmlhttp.open("GET", "test.php?func=sayHi", true);
xmlhttp.send();

(2) test.php file

<?php
    if ($_GET[&#39;func&#39;] == &#39;sayHi&#39;) {
        sayHi();
    }
    
    function sayHi () {
        echo "hello world"
    }
?>
