PHP的正則表達式的幫助更換

Question

我有一個字符串，一個是

[my_name] and another being <my_name> 

我需要使用正則表達式來與BOB搜索[]和<>括號內的任何文字和替換特定符號內的文本

我會提供示例代碼，但我甚至不知道從哪裏開始。任何幫助，將不勝感激

到目前爲止IV只是嘗試這樣做

$regex = [\^[*\]] 

想這將尋找在[]標籤什麼

Answer 1

我想，下面應該工作：

preg_replace('/([\[<])[^\]>]+([\]>])/', "$1BOB$2", $str); 

正則表達式的解釋：

([\[<]) -> First capturing group. Here we describe the starting characters using 
      a character class that contains [ and < (the [ is escaped as \[) 
[^\]>]+ -> The stuff that comes between the [ and ] or the <and>. This is a 
      character class that says we want any character other than a ] or >. 
      The ] is escaped as \]. 
([\]>]) -> The second capturing group. We we describe the ending characters using 
      another character class. This is similar to the first capturing group. 

替換模式使用反向引用來引用捕獲組。 $1表示第一個捕獲組，其可以包含[或<。第二捕獲組由$2表示，其可以包含]或>。

Answer 2

$str = "[my_name] and another being <my_name>"; 
$replace = "BOB"; 

preg_replace('/([\[<])[^\]]*([\]>])/i', "$1".$replace."$2", $str); 

Answer 3

要在這裏使用 preg_replace_callback

是一個簡單的例子

$template = "Hello [your_name], from [my_name]"; 
$data = array(
    "your_name"=>"Yevo", 
    "my_name"=>"Orangepill" 
); 

$func = function($matches) use ($data) { 
    print_r($matches); 
    return $data[$matches[1]]; 
}; 

echo preg_replace_callback('/[\[|<](.*)[\]\)]/U', $func, $template);
