Suppose you are in a php file and you want to run a javascript function that has both javascript and php inside of it. How would you go about doing this? Ex:

<?php
<script>
function myFunction(){
// php code
document.write("Hello World!");
}
</script>
?>

I know I can easily make a php function for this particular code, but just for future reference, I would like to know how to do this.

I apologize if this has been answered before but it seemed difficult to word in google search.

The PHP code has to output text that is valid inside the javascript. Something like this.

<?php
<script>
function myFunction(){
// php code
    var message = "<?php echo "My alert message"; ?>";
    window.alert(message);
}
</script>
?>

  • Don't forget to use `json_encode()` around any variable data so that things are escaped properly! – Brad Mar 25 '15 at 03:20
