ini files and automatic variables

subscriptions

I have a custom .config file that looks like this
[Host_Information]
mysql_host_name_e = "localhost"
absolute_name = "$_SERVER['USERNAME']"

I want to read it like this and set all the variables automagically:

$SETTINGS = parse_ini_file("./system.config");
while($key = key($SETTINGS))
{
    echo "key...".$key."...set to...".current($SETTINGS)."<br>";
$$key = current($SETTINGS); //variable variables
next($SETTINGS);
}

This works fine for the first variable mysql_host... but does not work for the second. It sets it to $SERVER['USERNAME'] rather than the value of it which would be for example = "FROGBOY" I tried using EVAL() and other approaches but could not get a $SERVER variable to work in the above code.

What is it that this simple caveman is missing in order to get the value of $_SERVER variables? Thanks.

<?php
foreach ($_SERVER as $key => $value) {
	echo "\$_SERVER[\"".$key."\"] => ".$value."<br>";
}
?>

Frederick shows in his code how to get the variables normally. I know how to do that...

what i am trying to do is to get the variable "absolute_name" to evaluate to "FROGBOY" rather than to "$_SERVER['USERNAME']"

Here is how it will evaluate with my code currently as shown in original post...

absolute_name = "$_SERVER['USERNAME']"

what i want is it to evaluate like this...

absolute_name = "FROGBOY"

Someone, key trying to educate me and thanks in advance for responses.

it looks like your origional idea of using variable variables is what you want.

$SETTINGS = parse_ini_file("./system.config");

foreach ($SETTINGS as $key => $value) {
    ${$key} = $value; // i like to use braces {} because its more readable, and obvious you didnt make a typo
}

you could also use extract(), as this is what its meant for.

but as far as getting
absolute_name = "$_SERVER['USERNAME']"

i dont think you can use variables in a ini file. just do it by hand

$absolute_name = $_SERVER['USERNAME'];
