what are you trying to do? maybe we can suggest something better?

you can certainly do that but with raw PHP or create a blade extension.. with raw php you might do:

eval($row->code)..

but be careful this is/can be dangerous if you dont know where the code is coming from

I'm using Laravel 4.2. It's a dynamic page system, and I want to add php functions to pages. I place "{{ eval($page->code) }}" to the blade, but it send error messages like this: "syntax error, unexpected '<'".

try <?php eval($page->code) ?>

Not working... Some tips?

Could be coming from the code you are evaling. And this sounds like a bad idea.

I've heard eval is evil

With Laravel 4.*, you must use the following syntax to disable escaping in Blade views:

{{{ $output }}}

And the new syntax since Laravel 5+:

{!! $output !!}

You can find more information in the laravel documentation
