You need to convert BB tags [hide_guest][/hide_guest] , I do this, but everything is the same:

 $parsered = 'Текст [hide_guest]Скрыто[/hide_guest] Текст'; $text = preg_replace_callback('#\[hide_guest\](.+?)\[/hide_guest\]#si', 'hide_guest', $parsered); function hide_guest($match) { return '<div class="spoiler">'.$match[1].'</div>'; } echo $text;

And what str_replace does not suit you? It will work much faster. This is how it should work correctly:

 $text = str_replace('[hide_guest]', '<div class="spoiler">', $parsered); $text = str_replace('[/hide_guest]', '</div>', $text);

And it works faster than regular expressions.

  • If I write the bb code in capital letters, then your replacement will stop working. - Visman
  • @Visman, the fact is that bb code is often inserted into js, ​​and the person writes according to the insertion anology, or there is a brief help saying [hide_guest] for example. And the people who will write in big letters with a specialist will see that the code did not work and edit the message. - Naumov
