PHP has long been a popular tool for web development. In order to meet the evolving needs of developers, the scripting language is regularly updated and new versions are published in the form of major and minor releases.

The Esc key at the top left of a PC keyboard is basically a relic from the days of command line-based operating systems such as DOS and UNIX.
