[Solved] How to make PHP BB Codes with RegExp?

Question

The user asked for something simple, so I gave him something simple.

$input = "[link=http://www.google.com]test[/link]";
$replacement = preg_replace('/\[link=(.*?)\](.*?)\[\/link\]/', '<a href="https://stackoverflow.com/questions/10458103/">$2</a>', $input);

Where /\[link=(.*?)\](.*?)\[\/link\]/ is the regex, <a href="https://stackoverflow.com/questions/10458103/">$2</a> is the format, $input is the input/data, and $replacement is the return.
