I have a string that looks like:
$string = '<a href="http://google.com">http://google.com</a>';
How can I remove the http:// part from the link text, but leave it in the href attribute?

Remove http://, www., and slashes from the URL First is trim() function, use for remove all slash from the URL. Second is preg_match() function, check http:// or https:// existed in URL. If yes then no need to http:// prepend otherwise you have to http:// prepend to URL. Third is parse_url() function, to parse the URL.
To remove http:// or https:// from a url, call the replace() method with the following regular expression - /^https?:\/\// and an empty string as parameters. The replace method will return a new string, where the http:// part is removed.
Without using a full blown parser, this may do the trick for most situations...
$str = '<a href="http://google.com">http://google.com</a>';
$regex = '/(?<!href=["\'])http:\/\//';
$str = preg_replace($regex, '', $str);
var_dump($str); // string(42) "<a href="http://google.com">google.com</a>"
It uses a negative lookbehind to make sure there is no href=" or href=' preceding it.
See it on IDEone.
It also takes into account people who delimit their attribute values with '.

$string = '<a href="http://google.com">http://google.com</a>';
$var = str_replace('>http://','>',$string);
Just tried this in IDEone.com and it has the desired effect.

In this simple case, the preg_replace function will probably work. For more stability, try using DOMDocument:
$string = '<a href="http://google.com">http://google.com</a>';
$dom = new DOMDocument;
$dom->loadXML($string);
$link = $dom->firstChild;
$link->nodeValue = str_replace('http://', '', $link->nodeValue);
$string = $dom->saveXML($link);
$str = 'http://www.google.com';
$str = preg_replace('#^https?://#', '', $str);
echo $str; // www.google.com
that will work for both http:// and https://
