[SOLVED] Formatting a URL

[JSHINER]

<?php

function clickable_short_url ($matches) {

	$url = array_shift($matches);
	$http = array_shift($matches);
	$url_text = strlen($url) >= 30 ?
		(substr($url, 0, 50)) :
		$url ;
	if (! $http) {
		$url = 'http://' . $url;
	}
	return '<a target="_blank" href="' . $url . '">My Website</a>';
}

$pattern = '%
	(http://)? ### optional http:// prefix
	(?(1)|www\.) ### require www. if there is no http://
	\S+ ### gobble anything but white space
%x'; 

echo preg_replace_callback($pattern, 'clickable_short_url', $page['person']['website']);

?>

 

The above is what I used to take http://www.site.com and www.site.com and convert them to clickable URL's within other text.

 

Now how can I make it so if the value of $website = site.com or www.site.com to have it automatically add either http://www. or http:// to the front of that?

This should do the trick:

 

 

Modified:

<?php
$url = 'http://www.mysite.com';
if(!preg_match("~^http://www.(.+)$~",$url)){
$url = 'http://www.'.$url;
$url = preg_replace("~http://www.http://~","http://www.",$url);
}

echo $url;
?>
