php REGEX help replace text inside of specific symbols

我有一个字符串，其中一个是

[my_name] and another being <my_name>

我需要使用正则表达式来搜索[]和<并将其替换为BOB>

我会提供示例代码，但我甚至不知道从哪里开始。如有任何帮助，不胜感激

到目前为止，我只是尝试了这个

  $regex = ['^[*']]

认为这将查找[]标签内的任何内容

我想下面的代码应该可以工作:

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

正则表达式解释:

(['[<]) -> 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.

替换模式使用反向引用来引用捕获组。$1表示第一个捕获组，它可以包含[或<。第二个捕获组由$2表示，它可以包含]或>。

$str = "[my_name] and another being <my_name>";
$replace = "BOB";
preg_replace('/(['[<])[^']]*([']>])/i', "$1".$replace."$2", $str);

你想使用preg_replace_callback这里有一个简单的例子

$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);
