PHP supports several data types, including:
- String – A string is a sequence of characters, enclosed in quotes (single or double).
- Integer – An integer is a whole number, positive or negative, without decimals.
- Float (also known as Double or Real) – A float is a number with a decimal point or an exponent.
- Boolean – A Boolean can have two values: true or false.
- Array – An array is an ordered collection of elements, each identified by a key.
- Object – An object is an instance of a class, which contains properties and methods.
- NULL – NULL is a special value that represents no value or a value that has not been set.
- Resource – A resource is a special variable that holds a reference to an external resource, such as a file handle.
It’s worth noting that PHP is a loosely typed language, which means that variables can change their data type dynamically during execution. For example, a variable that was previously assigned an integer value can later be assigned a string value. This flexibility can be both an advantage and a disadvantage, as it can lead to unexpected behavior if not carefully managed.
