double quotes x single quotes

[felipe_lopes]

Hi there!

I'd like to know when should I use double quotes and when to use single quotes, specially concerning arrays.

$array["name"]
$array['name']
$array[name]

I know by experience that both 3 can be used, depending on the situation.

When to use each case?

Thanx in advance

I think it's a matter of opinion. Personally, I use single quotes. Calling an array key is going to be literal. The third one should never be used. You need to have some sort of quoting.

"name" is processed for escape sequences and variables.

name is a constant which, if not present, is changed to 'name' by PHP

'name' is the correct way

Thank you guys!!

I'll be using single quotes with arrays now on!!

Depends what you are doing...

If you are using a variable as your array index, you'll want to use either double quotes, or no quotes at all, as it will not work with single quotes.
