PHP Kochi

A variable is a container for storing data for use in a program. The simplest way to store information in PHP is through variables. Variables can be stored in two ways: A string or an integer. A string is any sequence of characters enclosed in single or double quotes, e.g., 'Hello' or "World". They are often used to store text but may also contain numbers, special characters and even other strings (although this is not recommended). Strings are typically used to represent text that people can read. An integer is any whole number without a fractional component, e.g., 10 or -32000. They are often used to store numbers, but can also contain decimals when necessary (e.g., 7.5). 

PHP is a server-side scripting language designed for web development, but it can also be used for other purposes such as software development and database management. It is one of the most popular languages on the internet. PHP was originally created by Rasmus Lerdorf in 1994 and has been released under the general public license. PHP is a widely-used general-purpose scripting language that is especially suited to web development because it can create hypertext preprocessor (HTML) code and interact with web servers and databases to retrieve and display information from a database.
