How to call echo inside URL include?

Question

I want to do this: <?php include_once ("includes/'<?php echo $mymodule1; ?>'.php"); ?>

I try before with: <?php include_once ("includes/'.echo $mymodule1.'.php"); ?>

But not work :(

You can help me?, many thanks :)

Answer 1

include_once isn't really a function. Only kind of.

Putting a variable in a string:

include_once "includes/{$mymodule1}.php";

Answer 2

Write down the variable without the echo statement. Either do this:

<?php include_once ("includes/" . $mymodule1 . ".php"); ?>

or this:

<?php include_once ("includes/$mymodule1.php"); ?>

Answer 3

You can directly put the variable , no need for echo here

<?php 
include_once('includes/'.$yourvar.'.php');
?>
