I'm trying to make a game in HTML and PHP and I'm pretty new to coding. The point is I need to execute a PHP script by clicking an HTML element. Is this possible?
My code would look something like this
$money = 100;
and by clicking on:
<a>rob a shop</a>
it must excecute:
function rob_shop(){
$money += 75;
echo "You now have $money $";}

Answer 1

Try this, is PHP:
<?php
if (isset($_GET['money'])) {
$money = rob_shop($_GET['money']);
echo 'You now have: '.$money.'<br>';
} else {
$money = 100;
echo 'You now have: '.$money.'<br>';
}
echo 'rob a shop';
function rob_shop($money){
$money = $money + 75;
return $money;
}
?>
But the best way to do it is with ajax to avoid refreshing the page.

Answer 2

Add extra param to link and check with php and call function.
rob money
Then check for link
if (isset($_GET['fun']))
{
runFun();
}

Answer 3

you will need to use javascript and an ajax call or you could just do it in javascript.
<a id="shop">rob a shop</a>
<div id="response"></div>
// include jquery
<script>
$( "#shop" ).click(function() {
var money = money + 75;
$("#response").html( "YOU NOW HAVE $"+money );
// or make an ajax call to a php script and return the value
});
</script>
