Correct, [i]if[/i] you are using a string literal as the key. If you are using a[url=http://www.php.net/define]define()'d constant[/url] or a variable, then the key would not be quoted. (Technically, you [i]could[/i] double-quote a varialbe key, such as [b]$array["$key"][/b], but that's unnecessary and will add a tiny bit to the processing time.)
When to use quotes
I have a question about quotes. When should I quote the array key and how am I supposed to do that in a SQL command?
[code=php]
$query=”Update Column
Set Error=TRUE
Where llama[black]=alpaca”
Also, more verification on when exactly to use doubles and singles. I understand the variables in doubles vs singles but otherwise I still haven’t grasped it yet. I’m sorry about how vague that is, so you don’t have to answer it. I’d say I’m a beginner-intermediate level PHP programmer, but I just am still confused on this.
