php: Remove URL from string

Question

I have many strings (twitter tweets) from which I would like to remove the links when I echo them .

I have no control over the string and even though all the links star

Answer 1

If you want to remove everything, link and after the link, like via thing in your example, the below may help you:

$string = "The Third Culture: The Frontline of Global Thinkinghttp://is.gd/qFioda;via @edge";
$regex = "@(https?://([-\w\.]+[-\w])+(:\d+)?(/([\w/_\.#-]*(\?\S+)?[^\.\s])?).*$)@";
echo preg_replace($regex, ' ', $string);

If you want to keep them:

$string = "The Third Culture: The Frontline of Global Thinkinghttp://is.gd/qFioda;via @edge";
$regex = "@(https?://([-\w\.]+[-\w])+(:\d+)?(/([\w/_\.#-]*(\?\S+)?[^\.\s])?)?)@";
echo preg_replace($regex, ' ', $string);

Answer 2

I would do something like this:

$input = "The Third Culture: The Frontline of Global Thinkinghttp://is.gd/qFioda;via @edge";
$replace = '"(https?://.*)(?=;)"';

$output = preg_replace($replace, '', $input);
print_r($output);

It works for multiple occurances too:

$output = preg_replace($replace, '', $input."\n".$input);
print_r($output);
