Linkify PHP文本

我正在使用TinySong api來生成一個鏈接，它的工作原理，現在我嘗試使用它的鏈接。它沒有。我不知道爲什麼它不是linkifing我相信我使用了正確的變量。這是代碼。Linkify PHP文本

<?php 
    // linkify URLs 
    $pre = preg_replace(
    '/(https?:\/\/\S+)/', 
    '<a href="\1">\1</a>', 
    $pre 
); 
?>

如何使結果鏈接可點擊？我甚至使用正確的代碼？由於

你更可能，如果你在你的代碼，而不是傾銷數額是多少，整個腳本到一個代碼塊隔離特定問題領域得到積極的幫助。就我個人而言，我沒有願意或傾向於逐行篩選代碼來尋找潛在的問題。做一些預調試以找出沒有明確工作的東西並詢問有關情況。 – rdlowrey 2012-02-12 16:39:10

這是在網站運作良好，我用它來...

function find_urls($t){ 
    $reg_exUrl = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/"; 
    // Check if there is a url in the text 
    if(preg_match($reg_exUrl, $t, $url)) { 
     $add=''; 
     if (substr($url[0],(strlen($url[0])-1),strlen($url[0]))==")"){ 
      $url[0]=substr($url[0],0,(strlen($url[0])-1)); 
      $add=')'; 
     } else if (substr($url[0],(strlen($url[0])-1),strlen($url[0]))=="]"){ 
      $url[0]=substr($url[0],0,(strlen($url[0])-1)); 
      $add=']'; 
     } 
     // make the urls hyper links 
     return preg_replace($reg_exUrl, '<a href="'.$url[0].'">'.$url[0].'</a>'.$add, $t); 
    } else { 
     // if no urls in the text just return the text 
     return $t; 
    } 
}

這是唯一一個我發現，WWW工作。

function link_it($text) 
{ 
    $text= preg_replace("/(^|[\n ])([\w]*?)((ht|f)tp(s)?:\/\/[\w]+[^ \,\"\n\r\t<]*)/is", "$1$2<a  href=\"$3\" >$3</a>", $text); 
    $text= preg_replace("/(^|[\n ])([\w]*?)((www|ftp)\.[^ \,\"\t\n\r<]*)/is", "$1$2<a href=\"http://$3\" >$3</a>", $text); 
    $text= preg_replace("/(^|[\n ])([a-z0-9&\-_\.]+?)@([\w\-]+\.([\w\-\.]+)+)/i", "$1<a href=\"mailto:[email protected]$3\">[email protected]$3</a>", $text); 
    return($text); 
}

希望這會幫助別人
