Philip Norton has shared a script he's created in a new post today that lets you read from a Netscape-formatted cookie file (as outputted from a curl request).

This file is generated by PHP when it runs CURL (with the appropriate options enabled) and can be used in subsequent CURL calls. This file can be read to see what cookies where created after CURL has finished running. As an example, this is the sort of file that might be created during a typical CURL call.

The file is structured, plain-text content with information on the domain, path, security, name and expiration details of each cookie. His script parses out these details and pushes them into a basic array, prime for searching and sorting (and reuse) in your application.
