Req #38508 [Com]: Addition of Magic __toArray() function
Edit report at https://bugs.php.net/bug.php?id=38508edit=1 ID: 38508 Comment by: lukas at lu-x dot me Reported by:doublecompile at gmail dot com Summary:Addition of Magic __toArray() function Status: Closed Type: Feature/Change Request Package:Feature/Change Request PHP Version:* Block user comment: N Private report: N New Comment: I can only +1 the opinion from the last comment. Magic methods make PHP so powerful. So why limit it to string casting? The creator of the class should decide what values to return in which case - the user could just use the object in different ways without thinking about what methods would return what. It would all work automatically - using an array function would ask the object to return an array, using a string function would ask to return a string etc. So please implement magic methods for all data types in PHP - or, if that adds more complexity, add interfaces for that - the possibility to define custom conversion rules just has to exist! Previous Comments: [2013-05-24 03:39:23] rich dot remer at gmail dot com I think the main benefit it offers is the ability to control what happens during a cast operation. Right now, casting simple scalar values or NULL to an array works as expected. While it's possible to cast an object to an array, the semantics of what should happen in this situation are not nearly as clear. This really should be controlled by the class.

Hi guys. I'm dragging this out from the History. I think this is a great
suggestion as I use a lot of object that implement ArrayAccess so doing this
$someArray = (array) $obj;
that calls $obj-__toArray() would be a GREAT addition to PHP logic.

Why not simply have a method asArray() maybe even as par of an interface:
interface ArrayConversion
{
function asArray();
}
See, we have __toString as it is supported in language constructs like echo,
print and other internal functions. But we decided against an autoconversion
for arrays already. So itwill never be supported in any language construct.
That said there is no needed for this and nothing you would win against the
above interface. In fact you would make it php more complex because you'd add
just one more magic feature.

[2006-08-19 00:40:17] doublecompile at gmail dot com
Description:
Doing this:
$newarray = (array)$object;
will take the properties of an object and assign them as the values of keys in
an array.
As of PHP 5.2, doing this:
$stringified = (string)$object;
will call the magic __toString() function for a user-specified formatting of
the object as a string.
It would be a great addition to call a magic __toArray() function if an object
is cast as an array, instead of converting its public members to array
elements. (For instance, the class might not have public members). Classes
without the function could use the default method of mapping property names to
array keys.
Just my two cents.
Reproduce code:
---
?php
class magicExample
{
public $aoeu = htns;
function __toArray()
{
return array('foo'='bar');
}
}
$test = new magicExample();
$array = (array)$test;
print_r($array); // should show foo=bar, not aoeu=htns
?
