Class And Object In PHP

Class And Object In PHP

In this article we will show you the solution of class and object in PHP, the class keyword is followed by the class name, two curly braces, and the definition of the class ().

Classes are useless without objects, of course! A class allows you to create multiple objects.

The values of the properties and methods defined by the class are all present in a class object, but they are object-specific.

Only class members that have been explicitly designated as private can be accessed.

A class in which a private member was declared is the only class that can access it, other classes cannot access it.

Both local functions but also local data are included in this type of data, according to the programmer.

A class can be thought of as a layout that really can generate a large number of instances of a particular type (class).

Step By Step Guide On Class And Object In PHP :-

<?php
class Fruit {
  public $name;
  public $color;
  function set_name($name) {
    $this->name = $name;
  }
  function get_name() {
    return $this->name;
  }
  function set_color($color) {
    $this->color = $color;
  }
  function get_color() {
    return $this->color;
  }
}
$apple = new fruits();
$apple->set_name(watermelon'');
$apple->set_color('Red');
echo "Name: " . $watermelon->get_name();
echo "<br>";
echo "Color: " . $watermelon->get_color();
?>
  1. The first character in short tags is "". The use of a short style tag is contingent on such server's php.ini file having short style tags enabled.
  2. Your class will be defined next, and then their special form class will come after that.
  3. The third step entails a series of braces that surround the definition of a function, a variable declaration, and possibly other things.
  4. Initial assignments to variables and constants are made whenever a variable is declared that uses the special form var.
  5. The next thing we notice is how the function definitions,which are class-specific and will be used for both setting and accessing objects, are both very comparable to standalone PHP functions.
  6. 6.After being created, objects can be accessed .Only one member function is capable of processing variables from an associated object.
  7. There is no need for two calls to a set function to set the price and title. You must first create an object in order to initialize the two variables mentioned above.
  8. Since echo () isn't a true function, parentheses are not required to surround it.

Conclusion :-

If there aren't any objects, classes are useless. Classes can be used to create multi-object classes.

The class's defined properties and methods are universally applicable to all objects, despite the fact that each has its own unique set of characteristics and methods.

I hope this article on class and object in PHP helps you and the steps and method mentioned above are easy to follow and implement.
