PHP Data Types

[taxiongo]

PHP data types which we use to construct our variables:−
1. Integers − are whole numbers, without a decimal point, like 4195.
2. Doubles − are floating-point numbers, like 3.14159 or 49.1.
3. Booleans − have only two possible values either true or false.
4. NULL − is a special type that only has one value: NULL.
5. Strings − are sequences of characters, like 'PHP supports string operations.'
6. Arrays − are named and indexed collections of other values.
7. Objects − are instances of programmer-defined classes, which can package up both other kinds of values and functions that are specific to the class.
8. Resources − are special variables that hold references to resources external to PHP (such as database connections).

These data types in PHP can also be categorized into three categories:

scalar data types
compound data types
special data types

Understanding PHP data types is essential for constructing effective variables and writing robust code. By categorizing data into integers, doubles, booleans, NULL, strings, arrays, objects, and resources, developers can better manage and manipulate information within their applications.
