Possible to execute php string?

Question

If I have a variable that contains PHP code... something like this:

$PageCode = "<?php\r\nrequire_once(\"../code/rushs_flickr_photos.php\");\r\n?>";

Is it possible to execute that code within my page and assign it back to another variable? something like:

$PageContent = exec($PageCode);

Why would you want to put PHP code in a string and execute it instead of just requiring the file directly? If your answer is because you want to get the code to execute from the user, be aware this is a huge security issue. — Daniel Vandersluis

If you decide to fly in the face of security, just know that you don't need opening/closing php tags in code that will be eval()'d. — Fosco

Yes. You are looking for eval().

This is however considered very bad practice. Whatever it is that you are trying to do, there is most likely a better way.
