An operator is a special symbol that performs specific operations on one, two, or three operands and then returns a result.
Operators can be grouped according to the number of values they take.
Unary operators take only one value, for example, ++ (the increment operator).
Binary operators take two values, for example, arithmetic operators familiars like + (plus) and - (minus), and the majority of PHP operators.

Why PHP?

Yunus Kibebu — Sat, 01 Oct 2022 19:09:01 +0000

PHP is much easier to learn and use.
PHP was written specifically for dynamic Web page creation.
PHP is both free and cross-platform.
PHP is the most popular tool available for developing dynamic Web sites.
PHP you are not limited to output by HTML but include other outputting methods like images, PDF files, and even Flash movies (using libswf and Ming) generated on the fly. You can also output easily any text, such as XHTML and any other XML file. PHP can autogenerate these files, and save them in the file system, instead of printing them out, forming a server-side cache for your dynamic content.
One of the strongest and most significant features of PHP is its support for a wide range of databases. Writing a database-enabled web page is incredibly simple by using one of the database-specific extensions (e.g., MySQL), using an abstraction layer like PDO, or connecting to any database supporting the Open Database Connection standard via the ODBC extension. Other databases may utilize cURL or sockets, like CouchDB.
