Never ended up using it, was intended for tiny scripts that needed some simple environmental config.
_config.php
<?php
function _config($for=null)
{
$path = dirname(__FILE__) . '/config.xml';
$sig = md5($path);
if (defined($sig))
{
$config = unserialize(constant($sig));
}
else
{
$config = (object) array();
$xml = simplexml_load_file(dirname(__FILE__) . '/config.xml');
foreach ($xml->environments->children() AS $env)
{
$environment = $env->attributes()->name;
$config->{$environment} = (object) array();
foreach ($env->children() AS $variable)
{
$config->{$environment}->{$variable->attributes()->name} = (string) $variable;
}
}
define($sig,serialize($config));
}
if ($for==null)
{
$for = getenv('ENVIRONMENT');
if (empty($for))
{
$for = 'dev';
}
}
return isset($config->{$for}) ? $config->{$for} : (object) array();
}
config.xml
<?xml version="1.0" encoding="UTF-8"?>
<config>
<environments>
<environment name="dev">
<variable name="mysql_host">localhost</variable>
<variable name="mysql_port">3306</variable>
<variable name="mysql_user">root</variable>
<variable name="mysql_password">root</variable>
<variable name="mysql_database">portal</variable>
</environment>
</environments>
</config>
