HTML Forms and PHP
Here we would integrate the HTML forms and PHP by creating HTML forms to collect the user input turning that input into variables, and then doing various things with the information that we just collected.
Operators are used for performing specific tasks. The operators in PHP are same like other programming languages like Arithmetic operators, Assignment Operators, Comparison Operators, and logical operators.
Variable is an identifier used for storing the values like text strings, numbers or arrays which is stored in the system's memory and can be retrieved any time during the program.
What is a PHP File?
A PHP file includes PHP code, functions, text HTML tags and scripts that can process online forms, get the date and time, or access information from a database, such as MySQL database
