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.
<?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.
