RE: [PHP] object literals
exactly, why bother with JavaScript literal representation?
the foreach loop was just an alternative to explicit object cast cause you did
not like it I though it was more about control over what you want to cast
and what you do not ... in any case, what I said does not change cause in php
you have natural type hint over arrays and these are normally slightly faster
so I do not get why you want objects rather than arrays ...

First off, you compared the syntax between creating a PHP array and a
JavaScript object when the previous post specifically spoke about
getting a PHP OBJECT. Now you've made a rather lengthy and redundant
post trying to describe to me objects versus arrays in PHP. Lastly
you've suggested writing a function to convert an array to an object
using a foreach loop for the members which is completely unnecessary.
The following will suffice:
?php
function o( array $a )
{
return (object)$a;
}
?
... and the syntax will be:
?php
$o = o(array
(
'a' = b,
'c' = d,
));
?
But why bother when you could have just done:
?php
$o = (object)array
(
'a' = b,
'c' = d,
);
?
Cheers,
Rob.

as op, i think i'm going to stick with the cast. but it's been an
interesting thread and i learned some useful things.
Regardless though, it
comes down to the preference of the developer. It can certainly be
simpler to type:
$obj-blah-bleh-bluh;
than to type:
$obj['blah']['bleh']['blug'];
exactly. and i dislike typing
SELECT col FROM tab WHERE a= . $a['blah'] . AND ...
or even
SELECT col FROM tab WHERE a={$a['blah']} AND ...
when i could type
SELECT col FROM tab WHERE a=$a-blah AND ...
which is also easier to read.
i'm really lazy about typing.

Re: [PHP] object literals
Hi,
$x = (object) array('a'=1, 'b'=3, ...);
which works but isn't very lovely. it's neater in, for example, javascript.
Well, you could wrap it up in a function to make it a bit lovelier. Eg:
$foo = createObject(array('key' = 'value'));
It's not great, but PHP doesn't have a object literal syntax AFAIK.

You could use JSON,
$foo = json_decode('{a:1,b:3}');
but I guess that's not much better than Richard's suggestion.

Didn't think of that (well... it's new). That's actually much better I
think, since you get the added boon of ease of portability to JS (if
that's even a factor).

RE: [PHP] object literals
var o = {

so I guess the problem is a couple of quotes, isn't it?
otherwise define object statically and externally and use json_decode ;-)

is there a neat literal syntax for creating objects on the fly without
defining a type?
whenever i need to do it i do something like
$x = (object) array('a'=1, 'b'=3, ...);
which works but isn't very lovely. it's neater in, for example, javascript.

You made an array-- not an object.
