In object oriented programming terminology, constructor is a method defined inside a class that is called automatically at the time of creation of the object. Purpose of a constructor method is to initialise the object. In PHP, a method of special name __construct acts as a constructor.<\/p>\n\n\n\n

__construct ([ mixed $args = “” [, $… ]] ) : void<\/p>\n\n\n\n

Example<\/strong><\/p>\n\n\n\n

<?php<\/p>\n\n\n\n

class myclass{<\/p>\n\n\n\n

   function __construct(){<\/p>\n\n\n\n

      echo “object initialised”;<\/p>\n\n\n\n

   }<\/p>\n\n\n\n

}<\/p>\n\n\n\n

$obj=new myclass();<\/p>\n\n\n\n

?><\/p>\n\n\n\n

Output<\/strong><\/p>\n\n\n\n

This will produce the following result. \u2212<\/p>\n\n\n\n

object initialised<\/p>\n\n\n\n

Destructor<\/strong><\/p>\n\n\n\n

Destructor is a method automatically as soon as a garbage collector finds that a particular object has no more references. In PHP, the destructor method is named as __destruct. During the shutdown sequence too, objects will be destroyed. Destructor method doesn’t take any arguments, neither does it return any data type<\/p>\n\n\n\n

<?php<\/p>\n\n\n\n

class myclass{<\/p>\n\n\n\n

   function __construct(){<\/p>\n\n\n\n

      echo “object is initialised<\/p>\n\n\n\n

“;<\/p>\n\n\n\n

   }<\/p>\n\n\n\n

   function __destruct(){<\/p>\n\n\n\n

      echo “object is destroyed<\/p>\n\n\n\n

“;<\/p>\n\n\n\n

   }<\/p>\n\n\n\n

}<\/p>\n\n\n\n

$obj=new myclass();<\/p>\n\n\n\n

?><\/p>\n\n\n\n

Output<\/p>\n\n\n\n

This will show following result<\/p>\n\n\n\n
