如何將純文本鏈接/ URL轉換爲HTML（圖像和鏈接）

Question

因此，我有一大串文字可以包含指向網站或圖像的鏈接。我想將這些普通的URL轉換爲html元素。

示例輸入：

Hi my name is Harry you can find my website here: http://www.harry-rox.com. Oh and what do you think of my my wife: http://www.anothersite.com/wife.jpg? 

所需輸出：

Hi my name is Harry you can find my website here: <a href="http://www.harry-rox.com">http://www.harry-rox.com</a>. Oh and what do you think of my my wife: <img src="http://www.anothersite.com/wife.jpg" />? 

注;

我發現做這兩次轉換的一個（網址HREF元素，或圖像URL標記一些正則表達式的例子，但我似乎無法找到辦法把它們結合起來！:(

Answer 1

您可以通過以下方式做到這一點...

$str = 'Hi my name is Harry you can find my website here: http://www.harry-rox.com. Oh and what do you think of my my wife: http://www.anothersite.com/wife.jpg?'; 
$r1 = '/(http:\/\/[\S]+(?:jpg|jpeg|png|gif))/'; 
$r2 = '/(?<!src=")(http:\/\/[\S]+\b)/'; 
$sub1 = '<img src="$1"/>'; 
$sub2 = '<a href="$1">$1</a>'; 
$res = preg_replace($r1, $sub1, $str); 
$result = preg_replace($r2, $sub2, $res); 
echo $result;
