#12823 — Array key names

Just one simple question. Are spaces allowed in key names?
Such as $name=array("John Smith" +> "somethig").

I am testing it for you.

str@suse131:~> php -a
Interactive mode enabled

php > $a['is it really me?'] = 99.999;
php > print_r($a);
Array
(
    [is it really me?] => 99.999
)

/Str.

You Probably just typed it all in without any online testing.
The only true way of testing what is allowed and what isn't, is to do so on
the server you're going to be using.
e.g. your local machine you are using to test on at home has php 5.5.
while your host uses 5.3.
What worked for you suddenly fails.

richard I would be very careful telling others who have obviously more 
experience then you in PHP on how to and not to do coding/testing in 
PHP.  You may not really know enough about what you think you know.  I 
learned that some time ago.

For starters, Strobel is using what is called command prompt.  Great for 
testing a snippet of code without loading up the editor and such.

Secondly the OP is asking a simple question, which he could of actually 
tested on his own, and Strobel is wise enough to understand it was not 
affected by a minor version release.

Yes, I just typed it in :-) something I invite everybody to do.

And - the OP did not ask for a specific version.

And - this will not fail, it is too basic.

... (skip the rest about richard@noreplay as sysadmin)

Dipshit, we just had this fucking conversation. Piss off home and leave 
the technical help and advice to people who know what they're talking 
about, there's a good ignoramus.

For the OP, who hopefully has ignored every piece of claptrap richard has 
spoken:

A string style array index can comprise any valid sequence of string 
characters, including escape sequences for things such as tab, newline 
etc. It's a string, it can contain the same as any other string, the fact 
that it's being used as an array index does not change it's basic 
stringiness.

Indeed there's no reason not to do this, apart from it would be a really 
weird thing to do:

<?php

$_POST = array( "monkey" =>"\t\tsomething\t\t" );

$i = <<< EOT
This is my really long string array index.

It has several lines. In here I'm adding some post data:

The post data is the value of the monkey form field: '{$_POST['monkey']}'

That's a very bad example to give, because I'm using unvalidated and 
unverified user input. Jerry will call me out on this, and rightly so.

Meanwhile, here are some other things \n\n\n\n\n\t\t\t\t\t\nStuff

"and nonsense"

!!!!!!!!!!! <- madness

EOT;

$x = array( $i => "fred" );

var_dump( $x );

?>

Note - if you ever actually use an array key like that in production code 
then you deserve all the future pain and suffering that your code is 
surely going to cause you when it rises up as the toilet dragon of 
unhappiness and bites you very hard on the buttocks.

Actually, *any* string is allowed as key, however, not all strings will
be treated as string keys[1].
