Following Leslie around...... Creating an array, and printing it out with OO

[masood131]

For those of you who helped me with Class Human->leslie I appreciate it greatly. Working on that, I found out I still don't know how to declare an array, and print it out in OO environment, so I made this little script and sure enough it does not work. Would you give me some pointers on what I am doing wrong please.

This program is suppose to declare an array in a class and then pass it some numbers and print out the key and value. The initialization should take place in __construct().

<?php

class Human
{
  private $number;

  function __construct($key, $value) {
    $this->number [$key] = $value;
  }

  function __get($value)
  {
    foreach($number as $key => $value)
      echo $key.'=>'.$value.'<br />';
  }

}

$number = new Human();
$number->first = 1;
$number->second = 2;
$number->third = 3;
$number->fourth = 4;

?> 

p.s. I am trying to think of different examples to learn how a __construct works and what it does, how OO works, etc...

Although I read the php manual and I know what it does, I am having trouble implementing it. So, I am making these examples.

Thank you

your not passing any arguments to your construct. are you getting errors? i think you should be.

Hi Thrope,

You are right. I am getting an error, but I can't make sense of it. I thought when an object is created ($number->first = 1😉 the ($key = first) and ($value = 1) is automatically passed on to the construct. Am I wrong? How can I pass the values to my construct function?

im only new at this myself, and not 100% on how get works. but, because you have created your construct to except arguments, you need to pass values to it.

$number = new Human('first',1);

Thank you for the suggestion thrope, but I have to find a way to repeat this few times for secound and third as well without creating another instances. If I had only one $number = new Human('first',1); this would work fine, but I have to squeez in more than one in there.
