returning arrays from objects

[estricker]

Is there an easier way to 'copy' an array to outside an object. With easier way, I mean easier than this:

<?php
error_reporting(E_ALL | E_STRICT);

class Tab
{
public $second = array();
public function __construct()
{
$this->second[0] = "whatever";
$this->second[1] = "more whatever";
foreach ($this->second as $something)
{
return $this->second[$something];
}
}
}

$obj1 = new Tab();
foreach ($obj1->second as $something)
{
print $obj1->second[$something];
print $something;
}
?>

In the end I want to be able to print the array, or use it elsewhere.
Also I get these errors:

Notice: Undefined index: whatever in C:\Program Files\xampp\htdocs\Test\temp.php on line 17

Notice: Undefined index: whatever in C:\Program Files\xampp\htdocs\Test\temp.php on line 25
whatever
Notice: Undefined index: more whatever in C:\Program Files\xampp\htdocs\Test\temp.php on line 25
more whatever

Are these errors important, even though they are notices?

You get an notice when you try to use an variable which you haven't initialized yet. Though a notice isn't really important, it usually is an indication that your script isn't working like you want it to work. A well written script is ALWAYS notice (and error) free.

Besides this, your script looks a bit weird. For example, in your 'Tab' class constructor you have an foreach loop with an return statement. A return statement always terminates your loop so your foreach loop will never loop more than once.

Second, you loop through your array getting the array variables like this:

foreach ($this->second as $something)

This is correct, however on the next line you try to return a value in the array like this

return $this->second[$something];

This doesn't make sense. You first retrieve the value and then you want to return another value from the same array (which of cource hasen't been initialized). I think your code should be:

return $something;

If you want to have both the array key as the array value in you loop, your foreach should look like this:

foreach ($this->second as $key => $something) {
return $this->second[$key]; // Is exactly the same as return $something;
}

I suggest you read some more on (associative) arrays, because this is very basic stuff and it will all become clear once you get the hang of it.

Good luck,

oh jeah this is the mistake: i did'nt know how to call on the array, so i put both ways down, wrongly though. I assume with the foreach loop i schould use print $something;

foreach ($obj1->second as $something)
{
print $obj1->second[$something];
print $something;
}

correct me if im wrong

Hmm it actually was this simle:

<?php
error_reporting(E_ALL | E_STRICT);

class Tab
{
public $second = array();
public function __construct()
{
$this->second[0] = "whatever";
$this->second[1] = "more whatever";
foreach ($this->second as $something)
{
return $this->second;
}
}
}

$obj1 = new Tab();
foreach ($obj1->second as $something)
{
print $something;
}
?>

Ok,

I would also cut the foreach loop in the constructor. It really doesn't do anything usefull.
