Hello every one
I am facing problem in constructor .Even i know about this concept but using this key in calling function construction .
Please suggest some coding example .

 

What problem are you having exactly?

<?php
class mytest
  {
  # The constructor ....
  function __construct()
    {
    $this->test = "hello";
    }

  public function output()
    {
    print $this->test . "\n";
    }
  }

$test = new mytest;
$test->output();
?>

PHP:

You might also want to read up on constructors and destructors on the PHP site;
http://php.net/manual/en/language.oop5.decon.php

 

do you mean calling the constructor function? it is automatically called after instantiating an object

 

As he said, have a look at the use of constructors in the official site. It will help you.
