Ran into something small that might be helpful for other PHP types.  This isn’t rocket science, but I don’t see enough examples with static function calls for these functions.

array_walk lets you call a function that will be iterated over all members of an array.  In my template class, I had to append some text to the front and back of a search variable.  Instead of using the poorly performing foreach loop, I just ran the array_walk function and passed it a function that did the same thing.

array_walk($search, 'template_variable');

I decided that this was not what I wanted (since template_variable would be defined as a function in the global context), and I preferred putting related functions in the same class.  I tried this:

array_walk($search, 'self::template_variable');

Of course, this didn’t work.  array_walk is not a member of the Template class and as a result it just threw an error stating that “self::template_variable” didn’t exist.

array_walk($search, 'Template::template_variable');

This works fine.

-edit-

There’s something weird and inconsistent about all of this.  template_variable works even while private, which throws everything out of wack.
