Hello, I have great code to you :)

I found this code. It can call related keyword or lsi keyword from Google.

<?php
$contentstring = @file_get_contents("https://google.com/complete/search?output=toolbar&q=".urlencode($word3)); 

$content = @simplexml_load_string($contentstring );

	foreach($content->CompleteSuggestion as $c) {
		$term = (string) $c->suggestion->attributes()->data;
	echo '<u>'.$term.'</u>, ' ;
		}

unset($content);
echo '</p>';
?>

I try to change it to function.php but I have low skill. (I’m a musician T^T)

Can you covert it to wordpress plugin with shortcode like “Related Youtube Video Plugin”, your great plugin ??

This code will help people make a great On-Page SEO.
