making the following 2 assumptions:

URL begins with " http" (and there is only one instance within $a)
URL contains no spaces

something like the following (untested) code should work - (this can
most likely be optimized and I'd be interested to know how if anyone
can help out):

<?

$a = "This is http://www.yahoo.com";

// break everything to the left of "http"
$MyURL = substr($a, strpos($a, "http"));
$MyIntro = substr($a, 0, strpos($a, "http"));

// remove anything after URL (if existing)
if (strpos($MyURL," ")) { // there is a space in the string (after
URL)
$MyURL = substr($MyURL, 0, strpos($MyURL, " "));
}

$MyOutput = $MyIntro . "<a href=\"" . $MyURL . "\">" . $MyURL .
"</a>";

echo $MyOutput;
?>
