Call a function from one PHP file to another

Question

I am not quite sure why have I not been able to call a function from say File1 to File2 . I have used the require_once also .

Eg :

File1.php

<?php
function Test()
{
alert("Hello");
}
?>

File2

<?php
require_once("File1.php");

My code 
?>

<script type="text/javascript">

My code....

$("#email_summary").click(function() {
     <?php    
     Test();   
     ?>                            
});
</script>

Could you please let me know my mistake ? Thanks guys :)

you are calling php function in javascript. add <?php test(); ?> — عثمان غني

PHP is server side and javascript is client side. You can't directly call a PHP function from javascript. — Supericy

You mix different language. You cant call Test() only call it at a client side. — Sergey

you can not call php function by JavaScript like you did

$("#email_summary").click(function() {

     Test();                               
});
</script>

should be

$("#email_summary").click(function() {

    <?php echo Test();   ?>
});
</script>

and

function Test()
{
return 'alert("Hello")';
}

edit: if you want to make it work like your code you can do this by

File1.php

<?php function Test() { ?>

    alert("Hello");

<?php } ?>

and than just include like

<?php    
    Test();   
 ?>

@Justin sorry you need echo too

Dhruv Patel Over a year ago

This will never work, How are you mixing server side function with client side language.

Justin Over a year ago

It worked fine . What if I add echo instead of alert ? will it work ?

I meant instead of alert("Hello") I replace it by echo ("Hello") will it work ? will the echo statement work inside javascript ??
