Question

Here’s my question for today. I’m building (for fun) a simple templating engine. The basic idea is that I have a tag like this {blog:content} and I break it in a method and a action. The problem is when I want to call a static variable dynamically, I get the following error .

Parse error: parse error, expecting `','' or `';''

And the code:

 $class = 'Blog';
 $action = 'content';
 echo $class::$template[$action];

$template is a public static variable(array) inside my class, and is the one I want to retreive.

Answer 1

What about get_class_vars ?

class Blog {
    public static $template = array('content' => 'doodle');
}

Blog::$template['content'] = 'bubble';

$class = 'Blog';
$action = 'content';
$values = get_class_vars($class);

echo $values['template'][$action];

Will output ‘bubble’
