In PHP, there are several built-in data types that you can use to store different types of values. Here are some of the most common data types in PHP:
1. String: A string is a sequence of characters, enclosed in single quotes (”) or double quotes (“”). Example: “Hello, World!”
2. Integer: An integer is a whole number without any fractional parts. Example: 1234
3. Float: A float (or double) is a floating-point number that can have a fractional part. Example: 3.14
4. Boolean: A boolean represents either true or false. Example: true or false
5. Array: An array is an ordered collection of values, where each value is assigned a unique key. Example: $fruits = array(“apple”, “orange”, “banana”)
6. Object: An object is an instance of a class. It can have properties and methods. Example: $car = new Car()
7. Null: Null represents a variable with no value. Example: $value = null
8. Resource: A resource is a special variable that holds a reference to an external resource like a database connection or file handle.
9. Callable: A callable represents a function or method that can be called. It can be assigned to variables, passed as arguments, or used as a callback function.
10. Mixed: Mixed is a data type that can hold multiple types of values. Example: $mixedValue = “Hello, World!” or $mixedValue = 1234
11. Void: Void represents the absence of a value. It is commonly used to indicate that a function does not return any value.
These are the main data types in PHP, and you can use them to store and manipulate different types of data in your PHP programs.
