PHP Programming Basics Practice Test: Networking with PHP — Flashcards

PHP network functions allow us to create network-based applications. These functions can be used to establish network connections, send and receive data, and manipulate data packets over a network. They provide a comprehensive set of tools that enable us to interact with various network protocols such as HTTP, SMTP, FTP, and more.

Types of PHP Network Functions are:
1. Network Connection Functions: To create network connections between two devices - e.g. fsockopen().
2. Network Data Transfer Functions: To send and receive data over a network - e.g. fgetc(). 
3. Network Packet Functions: To manipulate data packets over a network - e.g. inet_ntop().
