How to add php code in a javascript function?

Answer 1

It's not possible.

JavaScript is a client-side language. PHP is a server-side language. For security reasons among others, JavaScript cannot use PHP.

However, as a substitute, you can call another page that uses PHP.

@Kamil, the PHP part is automatically removed when ran and then you're just left with the string. No real PHP operations can be performed with that method.

Answer 2

you could write this js code: document.write ("
<?php
echo "text";
?>
") this will execute the php code via js

of course this won't work if you are not on a server with php installed
