An integer data type is a non-decimal number between -2,147,483,648 and 2,147,483,647.

Rules for integers:

  • An integer must have at least one digit
  • An integer must not have a decimal point
  • An integer can be either positive or negative
  • Integers can be specified in: decimal (base 10), hexadecimal (base 16), octal (base 8), or binary (base 2) notation

In the following example $x is an integer. The PHP var_dump() function returns the data type and value:

Example Code: 


<?php

$x = 5985;
var_dump($x);

?>

Output:

The above code will produce the following result-


int(5985)
