Undefined Functions in Object-Oriented PHP

// March 29th, 2009 // Tech

Just had a big “duh” moment.

Have you ever had a PHP method (a function inside a class, in case you’re new to the whole OOP thing) cause a "Fatal Error: Call to undefined function 'whatever'..." even though you are 100% sure that the method has been defined?

You’re missing the $this-> before your call to the method. :P
