PHP - nested output buffering

Question

I have function that has :

ob_start();
//Include of some files
$content = ob_get_contents();
ob_end_clean();

Now in those includes is another function that uses the same code, and they seem to conflict. Is it possible to use them like this?

You can't declare the same function twice, you might be able to wrap your function definition in some kind of if(!function_exists('blah')) { function blah() { ... } } — Martin, May 17 '12 at 14:09

Try using output buffer like this :

ob_start();
// your includes
echo ob_get_clean();

Use this in all of your includes, and you will not get any errors

I had similar problem but mistakenly used ob_clean() instead ob_end_clean() - be aware of their difference! – besimple Sep 15 '15 at 21:22

Output buffering should be stackable, you just need to match ob_start with ob_end_clean. See http://php.net/ob_start
