Sentence to words function (PHP)

I'm looking for a mini function like this example;

ourfunction("our four words sentence") = <a href="/tag/our.html">our</a> <a href="/tag/four.html">four</a> <a href="/tag/words.html">words</a> <a href="/tag/sentence.html">sentence</a>

PHP:

Can someone show a function like this?

Thanks.

 

function ourfunction($words)
{
    $word = explode(" ", $words);
    foreach($word as $value)
    {
        //return "<a href='/tab/$value.html'>$value</a> ";
        echo "<a href='/tab/$value.html'>$value</a> ";
    }
}
ourfunction("our four words sentence");

PHP:

That should work.

 

EDIT: A bit too late.


Like this?

function words2links($text)
{
	$output = array();
	
	foreach (explode(' ', $text) AS $word)
	{
		if ($word = preg_replace('/\W/', null, $word))
		{
			$output[] = '<a href="/tag/' . $word . '.html">' . $word . '</a>';
		}
	}
	
	return implode(' ', $output);
}



echo words2links('hello this is a test .');

PHP:

 

All worked, thanks for your help. Reps added.
