怎樣的preg_replace所有鏈接到鏡像文件（*和*沒有HTTPS？）

Question

我使用Regexpal.com，我看到這個SO Question

我想不匹配的字符串。

我需要用字符串 <<IMAGE:{link}>> preg_replace所有鏈接到圖像的鏈接。 所以我想用(https?:\/\/)?\S*(jpg|png|jpeg|bmp|gif)OR有同樣的事情，荷蘭國際集團，但without前面的（HTTPS：//）

使：

Hi there this is an image link https://facebook.com/images/2323.jpg 
and this one is too mysite.org/1.png 

將成爲：

Hi there this is an image link 
<<IMAGE:https://facebook.com/images/2323.jpg>> and this one is too 
<<IMAGE:mysite.org/1.png>> 

Answer 1

我想你想要這個...

$str = 'Hi there this is an image link https://facebook.com/images/2323.jpg 
and this one is too mysite.org/1.png'; 

$regex = '/((https?:\/\/)?\S*(jpg|png|jpeg|bmp|gif))/'; 

$str = preg_replace($regex, '<<IMAGE:$1>>', $str); 
echo $str; 

輸出

Hi there this is an image link <<IMAGE:https://facebook.com/images/2323.jpg>> 
and this one is too <<IMAGE:mysite.org/1.png>>
