Data types are the different types of data we have in PHP. These are the different types of data that can be stored in variables. They include the following:

  • String – these are characters like Hello World. They are always wrapped inside double or single quotes.
  • Integer – these are whole numbers like 23000 and should never be in quotes.
  • Float (floating point numbers – also called double) – these are decimal numbers like 75.890. They should not be in quotes.
  • etc.
<?php

        $student = "Joan Smith";
	$tuition = 1500000;
	$amountPaid = 7000.349;


?>

Among others, these are the most common data types you will encounter in your everyday work and the above snippet shows you show they are used.
