问题 I found below lines on php.net manual which I couldn't understand what exactly they are trying to say. "As of PHP 5, an object variable doesn't contain the object itself as value anymore. It only contains an object identifier which allows object accessors to find the actual object. When an object is sent by argument, returned or assigned to another variable, the different variables are not aliases: they hold a copy of the identifier, which points to the same object.

问题 I have a server that has some very sensitive information on it, so security is a big issue. The user needs to be able to upload a video. I know allowing users to upload files poses a security threat because there is no 100% way to keep them from uploading non-videos. But I obviously can choose which files the server will keep.

问题 Disclaimer : I'm working on a legacy corporate WP site (PHP 5.3.3), and I can't make very many major breaking changes. I am adding pagination to an existing resources page (/resources). I'm fairly new to Wordpress in general, but I do have my page working and displaying the correct number of resources on page load. My question is: when you paginate in Wordpress using: <?php next_posts_link( 'More Resources' , $the_query->max_num_pages ); ?> It creates a link on the page, and when you click it
