public static $config = array(
'base_url' => '',
'environment' => '',
'database' => array(
'dbdriver' => '',
'dbhost' => '',
'dbname' => '',
'dbuser' => '',
'dbpass' => ''
),
I want to access the base_url key and assign it to a new static property $app but it is giving me syntax error of unexpected [
public static $app_path = self::config['base_url']; //unexpected [ error
分享 You want to access variable so you have to add $.
self::$config['base_url']
Read some more about that here.
Unfortunately you can't assign any variable (even static) to other static property as you can see in linked manual page.
Like any other PHP static variable, static properties may only be initialized using a literal or constant; expressions are not allowed. So while you may initialize a static property to an integer or array (for instance), you may not initialize it to another variable, to a function return value, or to an object.
