What are constructor and destructor in PHP ?

In PHP there are two special functions known as constructor and destructors which are used for creating and destroying an object respectively. A constructor is used mostly for sending parameters and creating any new object.

Example

class Animal
{
     public $name = "No-name animal" ;

     public function _construct() 
     {
              echo "I 'm alive!";
     } 
} 

For constructing a new object in the above code we will use the Coding line

$animal = new Animal();

The result that we will get is

<?php
class Animal
{
     public $name = "No-name animal" ;

     public function _construct($name) 
     {
           $this- >name = $name;
     } 
} 

$animal = new Animal ( "Bob the Dog") ;
echo $animal- >name;
? >

In the case of destructor

For the same example, if you want to dispose of an object then you need to do it manually. The object will get destroyed automatically which is not needed.

<?php
class Animal
{
     public $name = "No-name animal" ;

     public function _construct($name) 
     {
          echo "I 'm alive!";
          $this- >name = $name;
     } 
     
     public function _destruct () 
    {
             echo "I 'm dead now : (" ;
    } 
} 

$animal = new Animal("Bob") ;
echo "Name of the animal: " . $animal- >name; 
? >
