WP_Theme::_name_sort() private WP 3.4.0

Callback function for usort() to naturally sort themes by name.

Accesses the Name header directly from the class for maximum speed. Would choke on HTML but we don't care enough to slow it down with strip_tags().

{} It's a method of the class: WP_Theme{}

No Hooks.

Return

Int. Negative if $a falls lower in the natural order than $b. Zero if they fall equally. Greater than 0 if $a falls higher in the natural order than $b. Used with usort().

Usage

$result = WP_Theme::_name_sort( $a, $b );
$a(WP_Theme) (required)
First theme.
$b(WP_Theme) (required)
Second theme.
