Just like any other programming languages, we can have different types of variables.
<?php $var1 = 0; // Integer $var2 = 3.14; // Float $var3 = 'I am a string'; // String $var4 = true; // Boolean $arrayVar = array(250, 300, 325, 475); // Array
- Integer – Whole numbers. These can be either positive or negative.
- Float – Numbers with decimal places. These can also be either positive or negative.
- String – A mixture of letters, numbers, and symbols. Strings are surrounded by quotes.
- Boolean – One of two values: true or false. The value must not have any quotes as this would turn it into a string.
- Array – A multi-level storage type, similar to a table.
