why does this str_replace not work?

 

<?php 
$config = "this is the message";
$ch = str_replace("{config}",$config,$ch);
?>

<?php 
echo $ch; 
?>

 

it should show "this is the message"

$ch isn't being initialised, so it certainly can't contain "{config}", hence nothing gets replaced.

Try this...

 

<?php 
$config = "this is the message";
$ch = "bla bla {config}"
$ch = str_replace("{config}",$config,$ch);
?>

<?php 
echo $ch; 
?>

 

You must already have something in the $ch variable before you can replace things in it.
