Description:
------------
Quoted from the PHP Manual (CHM file version, generated: Sun Oct 05 02:13:52 2003)

----------
Example 2-7. Printing data from our form

Hi <?php echo $_POST["name"]; ?>.
You are <?php echo $_POST["age"]; ?> years old.
----------

In order to avoid parse errors, it seems like this should instead read:

----------
Example 2-7. Printing data from our form

Hi <?php echo $_POST[name]; ?>.
You are <?php echo $_POST[age]; ?> years old.
----------

Thanks!

Thanks for your comments, but this is not the case. :)

In general, you must quote the keys used in array operations. If you don't, you'll get a lot of notices when using E_ALL reporting mode. (And you are using E_ALL, aren't you?)

So really, the ["key"] notation is correct. [key] is just a hack, and shouldn't be used. ['key'], of course, would be best. =)

Using quotes only leads to parse errors in strings when not using curly braces, so "foo $array['bar']" would be incorrect, but that's the only case you don't use quotes. Using "foo {$array["bar"]}" would be correct again. See the manual page at http://php.net/types.string for further reference.
