replacing variables in output in php

Right now I have this code.

<?php error_reporting(E_ALL); require_once('content_config.php'); function callback($buffer) { // replace all the apples with oranges foreach ($config as $key => $value) { $buffer = str_replace($key, $value, $buffer); } return $buffer; } ob_start("callback"); ?> some content <?php ob_end_flush(); ?>

in the content_config.php file:

$config['SiteName'] = 'MySiteName'; $config['SiteAuthor'] = 'thatGuy';

What I want to do is that I want to replace the placeholders that with the key of the config array with its value.

Right now, it doesn't work :(

-------------Problems Reply------------

your callback function cant see $config. you must either pass it as an argument or declare it global

global $config;

as an aside you can use arrays with str_replace

$buffer = str_replace(array_keys($config), array_values($config), $buffer);

this avoids a loop, which is always good.
