Get Background Color

gistfile1.aw

<?php
function mytheme_get_background_color() {
	$color = get_background_color();
	if ( ! ctype_xdigit( $color ) )
		return 'transparent';
	if ( ! in_array( strlen( $color ), array( 3, 6 ) ) )
		return 'transparent';
	return '#' . $color;
}

Why not use a switch statement?

Never used one in this context before. How would it work?

No need for a switch. Try this:

if( ctype_xdigit($color) && ( (3 == strlen($color)) || (6 == strlen($color)) ){
return '#' . $color;
} else {
return 'transparent';
}

The above should work since ctype_xdigit() will return FALSE if it detects a null (i.e., no color set).

Great call with the empty check. It's probably not needed at all. I always miss these little opportunities to optimize.
