Here is the code for simple arithmetic operations using PHP like Addition, Subtraction, Multiplication and Division. These code samples are just for practice purpose, it may have issues or bugs.<\/p>\n

Here we achieve these operations using switch case and functions in php. This code is expected to run on command line.<\/p>\n
