How to access a var with "-" in PHP

Question

For first time I found this problem, see I've a array of objetcs and I access them as follow:

$arrayOfObjects[$pos]->value;

But my problem is that one of the array values have a "-" meaning the value is e-mail so when I do this:

$arrayOfObjects[$pos]->e-mail;

I get an error, how do I handle this? The var can't be changed!!

best answer is not to have object elements with hyphens in the first place. (there are solutions, but the code is ugly; best way is to avoid it completely) — Spudley, Jul 30 '13 at 15:00

If you absolutely have to have the hyphens, you can access it like:

$arrayOfObjects[$pos]->{'e-mail'};

Sometimes it can't be avoided if the data has been retrieved from a call to a remote 3rd party system – Mark Baker Jul 30 '13 at 15:14

You cannot access a variable with a dash in it in that fashion.

Try this:

$arrayOfObjects[$pos]['e-mail'];

This is using an object like an array, which is bad practice in my opinion. But I could be wrong.. – Ron van der Heijden Jul 30 '13 at 15:02
