PHP code attribution

Hello PHP peeps, I am curious as to the practical usage guidelines for your documentation with respect to copy/pasting code. For instance, am I allowed to copy/paste code examples from php.net and use them in my project? I recently discovered that the code is covered under CC 3.0 Attribution. http://php.net/license/index.php#doc-lic ..I hope you can forgive me because, until now, I have not been concerned with attributing code that I pull from the documentation for usage in my projects.
