What is method and property in php?
Class member variables are called properties. They may be referred to using other terms such as fields, but for the purposes of this reference properties will be used. They are defined by using at least one modifier (such as Visibility, Static
Keyword, or, as of PHP 8.1.0, readonly), optionally (except for Show
Within class methods non-static properties may be accessed by using The pseudo-variable $this is available inside any class method when that method is called from within an object context. $this is the value of the calling object. Example #1 Property declarations
$var8 = <<<'EOD'
Type declarationsAs of PHP 7.4.0, property definitions can include Type declarations, with the exception of callable. Example #2 Example of typed properties
__construct(int $id, ?string $name) The above example will output: Typed properties must be initialized before accessing, otherwise an Error is thrown. Example #3 Accessing properties
setNumberOfSides(int $numberOfSides): void The above example will output: string(8) "triangle" int(3) string(6) "circle" Fatal error: Uncaught Error: Typed property Shape::$numberOfSides must not be accessed before initialization Readonly properties As of PHP 8.1.0, a property can be declared with the Example #4 Example of readonly properties
__construct(string $prop) {
A readonly property can only be initialized once, and only from the scope where it has been declared. Any other assignment or modification of the property will result in an Error exception. Example #5 Illegal initialization of readonly properties
Modifications are not necessarily plain assignments, all of the following will also result in an Error exception:
However, readonly properties do not preclude interior mutability. Objects (or resources) stored in readonly properties may still be modified internally:

What is property and method?In most cases, methods are actions and properties are qualities. Using a method causes something to happen to an object, while using a property returns information about the object or causes a quality about the object to change.
What is a property in PHP?Property is sometimes referred to as attribute or field. In PHP, a property is qualified by one of the access specifier keywords, public, private or protected. Name of property could be any valid label in PHP. Value of property can be different for each instance of class.
What is a method in PHP?Methods are used to perform actions. In Object Oriented Programming in PHP, methods are functions inside classes. Their declaration and behavior are almost similar to normal functions, except their special uses inside the class.
Is property and method same?Properties define the characteristics of an object such as Size, Color etc. or sometimes the way in which it behaves. A method is an action that can be performed on objects. For example, a dog is an object.
