[Plugin: WordPress SEO by Yoast] Using the 'Focus Keyword' in PHP

Hi there, wonderful plugin.

Here is a code snipped for anyone trying to use the “Focus Keyword” in their PHP.

1) Place the following code into your theme’s functions.php file.

/*--------------------------------------*/
/* Use WP SEO Focus Keyword in PHP
/*--------------------------------------*/
if(!function_exists('wpseoFocusKW'))
{
		function wpseoFocusKW()
		{
			$focuskw = wpseo_get_value('focuskw', $post->ID);
			echo $focuskw;
		}
}

2) Place this code where you want the Focus Keyword to display.

<?php wpseoFocusKW();?>

3) Enjoy your Focus Keyword anywhere you want!**

**I cannot vouch for it working everywhere on every single theme and plugin, but technically it should work 😉
