Class to manipulate .ini files in php - php

Question

I've been playing around with a php class I found on the net called Config Magik that I use to store some info in a INI file but have recently run into some problems when using removeKey. I wanted to know if someone can point me to a similar class that would work as well or better. Or if there is a better way to go about this.
This is my function right now, after playing around with it like crazy, so it is probably very faulty.
require_once('class.ConfigMagik.php');
$config = new ConfigMagik('config.ini', true, true);
if(!empty($_GET)){
if(!is_writeable('config.ini')){
echo 'Could not write to config.ini';
return false;
}
//if there is no section parameter, we will not do anything.
if(!isset($_GET['section'])){
echo false; return false;
} else {
$section_name = $_GET['section'];
unset($_GET['section']); //Unset section so that we can use the GET variable to manipulate the other parameters in a foreach loop.
if (!empty($_GET)){
foreach ($_GET as $var => $value){
echo $var.'='.$_GET[$var].'<br />';
//Check if said variable $var exists in the section.
if($config->get($var, $section_name) !== NULL){
//Set variable value.
try{
$config->set($var, $value, $section_name);
echo 'Setting variable '. $var.' to '.$value.' on section '.$section_name;
} catch(Exception $e) {
echo 'Could not set variable '.$var;
echo $e;
return false;
}
} else {
echo $var.' does not exist <br />';
}
}
}
try{
$section = $config->get($section_name); //Get the entire section so that we can manipulate it.
echo '<pre>';print_r($section);echo '</pre>';
foreach ($section as $title=>$value){
if(!isset($_GET[$title]) && isset($section[$title])){
try{
$config->removeKey($title, $section_name);
echo '<b>'.$title.'</b>: removed <br />';
} catch(Exception $e){
echo $e;
}
}
}
} catch(Exception $e){
echo $e;
}
$config->save();
//echo $config->toString('HTML');
echo true;
return true;
}
} else { RUN SOME HTML }
It basically saves the settings I pass on from the GET parameters and if the parameters are not there it is supposed to delete it. When I get to $config->removeKey($title, $section_name); in the last try catch statement it won't save automatically (as it should), so I tried running $config->save() and I ended up with a ini file that had section = array everywhere. Any advice will be appreciated as I've been learning PHP on the web for the last few weeks so I believe I've got a ways to go.
I have definitely isolated the problem to the $config->save() part, just don't know how to solve it.
Thanks in advance.

I have been using Zend_Config_Ini and Zend_Config_Writer_Ini in the past and was satisfied with the features. You will have extract the whole library/Zend/Config folder from Zend Framework and make Zend_Exception available though.
