How to replace all tags with RegExp in PHP?

Question

PHP

I implemented comments on my project and when quoting, I decided to enter the following tag as a name: [@UserName] , which in turn will be a link when displayed on the site.
How to replace all such tags with links in the entire text.
Example: " [@Vasya Pupkin], hello!! Do you know this dude [@Vladimir Vladimirovich]??? "
Will be displayed as:

<a href="/user/Вася Пупкин">@Вася Пупкин</a>, привет!! Ты знаешь этого чувака <a href="/user/Вася Пупкин">@Владимир Владимирович</a>???

My crooked code only replaces @ :

echo preg_replace("/#(\w*[a-zA-Z_0-9]+\w*)/", "\1", $text);

Answer 1

preg_replace('/\[(@([^\]]+))\]/', '<a href="/user/$2">$1</a>', $text);
