using these
Yii::app()->params['your_awesome_name'] =  ' Awesome Name Here ';


and to access it , it will be like ..



$awesome_name = Yii::app()->params['your_awesome_name'];
$awesome_name = $awesome_name ? $awesome_name: "Default Awesome Name Here";

PHP : Add Item on array

So I got this problem that I encounter today.
Heres the code

$list_items = array(
array('label'=>'Dashboard'),
array('label'=>'Home','icon' => 'home', 'url'=>'#'),
array('label'=>'Residents', 'url'=>Yii::app()->createUrl('residents')),
array('label'=>'Users', 'url'=>Yii::app()->createUrl('users')),
array('label'=>'Reports'),
array('label'=>'Population Growth', 'url'=> Yii::app()->createUrl('residents/chart/population_growth')),
array('label' => 'Population by Year','url' => Yii::app()->createUrl('residents/chart/population_by_year')),
array('label' => 'Distribution of Population','url' => Yii::app()->createUrl('residents/chart/distribution_population'))
);
foreach ($list_items as $item) {
if ($item['label']===$selected_menu) {
$item['active']=true;
}
}

Code says that if the $selected_menu is equal to the label add an new item with key 'active' and a value of true.






First , ofcourse it doesnt work . 
After reading few comments  , turns out that I need to pass by reference to add new item on the $list_items , through the use of &     *yes thats an ampersand character



The working code now looks like this 

$list_items = array(
array('label'=>'Dashboard'),
array('label'=>'Home','icon' => 'home', 'url'=>'#'),
array('label'=>'Residents', 'url'=>Yii::app()->createUrl('residents')),
array('label'=>'Users', 'url'=>Yii::app()->createUrl('users')),
array('label'=>'Reports'),
array('label'=>'Population Growth', 'url'=> Yii::app()->createUrl('residents/chart/population_growth')),
array('label' => 'Population by Year','url' => Yii::app()->createUrl('residents/chart/population_by_year')),
array('label' => 'Distribution of Population','url' => Yii::app()->createUrl('residents/chart/distribution_population'))
);

#heres the solution, using the ampersand
foreach ($list_items as &$item) {
if ($item['label']===$selected_menu) {
$item['active']=true;
}

}
