PHP Numbers

Summary

PHP recognizes two groups of prime numbers, namely integers for integers and floats for decimal numbers. This lesson discusses how PHP differentiates between the two, from basic arithmetic operations, to numerical type-checking and decomposition. Understanding numbers is important because almost all applications process data in this form.

Key points

An integer is an integer, a float is a decimal number
PHP automatically determines the type of a number from its value form
The operator % counts the remainder of the, / for the normal distribution
Use is_numeric() to check whether the value is numeric
