How to Use SSL Sockets with PHP

SSL sockets are perfect for sending secure data. With certificates, you can verify the identify of the host, the client, or both.

Examples include raw socket communication as well as the common HTTPS protocol.

Preventing Cross-site Scripting (XSS) with CakePHP 2.x

Without proper care, developers can leave their CakePHP website open to cross-site scripting attacks. Controllers using scaffold functions do not take care to sanitize data, and leaves the website vulnerable.

In a perfect world I would agree with this approach, but it is easy to forget to sanitize output every time, or for an amateur developer to be ignorant of the dangers.

AJAX Pagination and Sorting with CakePHP 2.x

Alternatively you could set specific elements of the array inside an action with a call like $paginate['conditions'] = array();
