    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";

通過cut，你的意思是完全刪除並替換爲空字符串，而不記得你刪除了什麼？ – 2010-02-16 22:22:24

你可以嘗試一些簡單的像這樣：

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

將得到的字符串中離開雙空間雖然。你可以處理，但會稍微複雜一些。我也不檢查刪除的文本是否有效的URL。任何包含：//被刪除。

天真的方法：

preg_replace('/http[^\s]+/', "", $str)

替換以「http」開始，由非空格字符，用一個空字符串的任何字符串。

這是假設你只得到http。否則，少一點天真（但仍主要是幼稚）：

preg_replace('#[a-z]+://[^\s]+#', "", $str)

將結果分配給某些內容以避免混淆是一個好主意。關於SO的常見問題是'爲什麼替代方法不做任何事情？或該主題的變化。 – 2010-02-16 22:27:13

啊，好點。感謝您的提示:) – 2010-02-16 22:30:04
