PHP data types
Integers
Integers are always the numbers where decimal numbers are not used, or in simple words non-decimal numbers are integers like 8 and 53. In integers Point is not used.
Floats
This is absolutely opposite of integer numbers, like in integers point is not used but in floats point is used, in simple words decimal numbers are floats like 6.5, 5.4, .01 are the floats.
Strings
This simply means text.
Boolean values
Meaning true/false statements.
Arrays
Arrays are variables that store several values. We will talk about
them in detail further below.
Objects
Objects store both data and information on how to process it.
Resources
These are references to functions and resources outside of PHP.
NULL
A variable that is NULL doesn’t have any value.
In PHP, data types are used to specify the type of data that a variable can hold. Here are some commonly used data types in PHP along with examples:
- Integer: Represents whole numbers without decimals.
$age = 25;
- Float (Floating-point number or Double): Represents numbers with decimals.
$price = 10.99;
- String: Represents a sequence of characters.
$name = "John Doe";
- Boolean: Represents a true/false value.
$is_active = true;
- Array: Represents a collection of key-value pairs or indexed values.
$fruits = array("Apple", "Banana", "Orange");
- Object: Represents an instance of a class.
class Person {
public $name;
public $age;
}
$person = new Person();
$person->name = "John";
$person->age = 30;
- Null: Represents a variable with no value assigned.
$address = null;
- Resource: Represents a special variable that holds a reference to an external resource.
$file = fopen("example.txt", "r");
- Callable: Represents a function or method that can be called.
function greet() {
echo "Hello, World!";
}
$func = 'greet';
$func(); // Output: Hello, World!
These are just a few examples of how to use data types in PHP. It's important to note that PHP is a loosely typed language, so you don't need to explicitly declare the data type of a variable. The data type of a variable is determined by the value it holds. However, you can enforce type declarations in PHP 7 and later using type hinting.
