The WordPress Customizer

The WordPress Customizer is an interface for drafting changes to content while previewing the changes before they are saved. This is an alternative to the "save and suprise" model of changing settings without knowing what exactly will happen.

The customizer can be accessed in the admin interface under Appearance > Customize.

#19909 is the trac ticket that introduced the Customizer during the 3.4 release cycle.

C++ Pointer Tutorial

Because pointers can be ugh

"Regular" variables (not pointers)

To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".

When declaring a variable by identifier (or name), the variable is synonymous with its value.

PHP is a general purpose programming language with a focus on web programming.

PHP is a dynamically typed language; the type of variables is not known and type-checking occurs at run-time.

function takes_anything($anything) {
	// ...
}

takes_anything( 12345 );
