Automatic Hyperlinking

[mpridham]

(Sorry for the double post. I just realized I posted it in the math forum by mistake)

 

I have created a very simple blog application and would like to add the functionality of having hyperlinks automatically created when a url is entered. For instance, when I post a blog entry with something like "Go to www.foobar.com", I would like it to automatically add the anchor tags (like this site does.)

 

Any ideas?

 

Thanks

Just use some simple regex to scan posts for the links, and then replace them with the linkified version. preg_match() or preg_replace are probably good functions to look at.

^^ a personal test lol.. but besides that let me write up something

 

but you have to study some regex its very neat

 

/((?:www\.|https?:\/\/)[.a-z0-9;&?\/-]+?)/i

thats really really simple but should do your job (havn't tested it)

<?php
$text = "omg hey go to http://www.lovinglori.com/signatures.php www.google.com its so cool!";
function link($a,$b) {
	if ($a == 'http://' || $a == "https://") {
		return "<a href='{$b}'>$b</a>";
	}
	else {
		return "<a href='http://{$b}'>$b</a>";
	}
}
echo preg_replace("/((www\.|https?:\/\/)[.a-z0-9;&?\/-]+)/ie","link('\\2','\\1')",$text);
?>
