需要帮助转换布尔值

Question

this is actually WordPress but I think it is more of PHP question.

I am using SMOF framework (it is for theme option setting) and flexslider. TO combine bothe of them, in one of flexslider option, I have to use whether "true" or "false". The thing is, SMOF returns "0" and "1" instead of "true" or "false" - the word. So I need to convert "0" to "false" and "1" to "true"

I have this code:

function isBoolean($slider_loop) {
    $slider_loop = $smof_data['slider_loop'];
   if ($slider_loop === "true") {
      return true;
   } else {
      return false;
   }
   return $slider_loop;
}

..., and then in flexslider's "side":

animationLoop: "<?php echo isBoolean($slider_loop); ?>"

but it is not working.

Ideally, it should be something like this:

animationLoop: "<?php echo $smof_data['slider_loop'] 
// this return "0" and "1", while it should be "true" or "false" for flexslider to work ?>"

So, how should I do it?

Thanks in advance.

How about you take advantage of dynamic typing and type casting ? It's as simple as:

return (bool)$smof_data['slider_loop'];
