    Madonna - The power of goodbye Your heart is not open, so I must go The spell has been broken...I 
    loved you so Freedom comes when you learn to let go Creation comes when you learn to say no You were 
    my lesson I had to learn I was your fortress you had to burn Pain is a warning that something's wrong 
    I pray to God that it won't be long Do ya wanna go higher? Chorus: There's nothing left to try 
    There's no place left to hide There's no greater power than the power of good-bye Your heart is not 
    open, so I must go The spell has been broken...I loved you so You were my lesson I had to learn I was 
    your fortress Chorus: There's nothing left to lose There's no more heart to bruise There's no greater 
    power than the power of good-bye Bridge: Learn to say good-bye I yearn to say good-bye Chorus: There's 
    nothing left to try There's no more places to hide There's no greater power than the power of good-bye 
    There's nothing left to lose There's no more heart to bruise There's no greater power than the power 
    of good-bye";

How do I in this text completely cut all links?

Answer 1

You could try something simple like this:

$text = preg_replace("#\S+://\S+#", "", $text);

It will leave double spaces in the resulting string though. You could handle that, but it would get slightly more complicated. I also don't check if the text removed are valid URLs. Anything containing :// is removed.
