Set and Get Array Methods

z3r0_f4ct0r

Hi,

I just signed up to the phpbuilder forum, I've been looking for a good php forum for general coding questions hopefully this is the place to be! 🙂

So I'll get right to it. I'm developing a class w/ a private array that I would like to provide set and get functions, I'm a little rusty w/ php so I'm not to sure if how to actually access the functions properly.

Here's the basic syntax, I would appreciate feedback.

Thanks,
z3r0

class foo
{
       private $array_name = array();

   function __construct() {}

public function getArray($key)
{
	return $this->$array_name[$key];
}

public function setArray($key, $value)
{
	$array_name[$key] = $value;
}
}

Actual Call?


$foo = new foo;

$foo->setArray("name","John Doe");
echo $foo->getArray("name");

class foo
{
   private $array_name = array();

   public function getArray($key)
   {
      return $this->array_name[$key]; // removed "$" before "array_name"
   }

   public function setArray($key, $value)
   {
      $this->array_name[$key] = $value; // added "$this->"
   }
}

It sounds like getArray and setArray would be more appropriately named getElement and setElement respectively... or there might be an ever better name that we could suggest if we knew what exactly your class is supposed to model.

Call them offsetGet and offsetSet; add offsetExists and offsetUnset; declare foo as implementing ArrayAccess:

class foo implements ArrayAccess
{

private $array_name  = array();

function offsetExists($key)
{
	return isset($this->array_name[$key]); // or array_key_exists
}
function offsetGet($key)
{
	return $this->array_name[$key];
}
function offsetSet($key, $value)
{
	return $this->array_name[$key] = $value;
}
function offsetUnset($key)
{
	unset($this->array_name[$key]);
}
}

Now you can write

$foo = new foo;
$foo['name'] = 'John Doe';
echo $foo['name'];

Thanks for the replies in advance.

Let me clarify a bit more. I basically want to create a validate class, when I call the object $foo I would pass all the information from the $_POST array of the form, validate the data then store it in a new array referenced by calling the object

$foo->getArray('validatedArray')

I'm still thinking about how to approach this. Maybe instead of creating a validate class, I should really be creating a form class, where I basically store all the form data in an object, then pass the object to another class (validate) to validate the data, if the data isn't valid perhaps have another object (error) and return for correction.

$contact_formObj = new Form; // Called in contact.php
$contact_formObj($_POST); // Called in contact.php

// pass $contact_formObj to process.php
// store $contact_formObj in a session?


$validate_data = new Validate; // Called in process.php
$validate_data($contact_form); // Called in process.php

// Called in process.php or possibly returned to contact.php to display errors

$error_container = new ErrorContainer;

Hope this makes sense. I'll keep playing w/ the code and post any progress.

Well I did some digging, I might be trying to reinvent the wheel.

HTML_QuickForm

Symfony Web Form

Though MVC seems a little funky.
