Well, I didn’t know. But I figured it out while working with SimpleXML to parse an XML document where the node name had a hyphen in it. I was finding a way to refer that element as a SimpleXMLElement and found a nifty note in PHP Manual. It says if you have unsupported (unsupported in PHP Lexicon for a variable name) characters inside the name of a node, you can access it using a special pattern {‘name’}.
So I tried the following code and it show that you can have a class variable named “i can have cheese burger”
$s = new stdClass();
$s->{'i can have cheese burger'} = "Oh Yeaaah";
echo $s->{'i can have cheese burger'}; //it will output "Oh Yeeah"
and if you print_f the object $s, you will see the following
stdClass Object
(
[i can have cheese burger] => Oh Yeeah
)
Well, Its funny! – I love having some fun writing PHP code!

That’s funny that you found this today as I stumbled across the same thing today by accident.
I was running a PostgreSQL query that aliased fields with meaningful names:
SELECT name AS “User Name”, …..
and did a var_dump() of pg_fetch_object() and noticed that the member variable had a space in it. Had no idea how to access it so I used a fetch assoc instead.
Well done Amy for doing the 100 word challenge house ponits when you get back! I like the ideas just remember to check your tenses. Have a good week.
$s = new stdClass();
$s->{“is it funny???”} = “Oh Yeaaah!!”;
echo $s->{“is it funny???”};
${‘i can have cheese burger’} = “Oh Yeeah”;
echo ${‘i can have cheese burger’};
Ya, This is funny. It also prove php is a Flexible language.
