heredocs and numbers in indexes

I have an array;

$array['1a'] = 'something';
$array['a1'] = 'something else';

I can do this: echo $array['1a'];

And I can do this:

$content =<<<content

$array[a1]

content;

But if the index starts with a digit, php fails looking for the trailing
"]".

$content =<<<content

$array[1a]

content;

Why is that? Is there a fix other than renaming the indexes?
{$array[1a]} or {$array['1a']} does not work.

Is this a bug or is it a feature I don't understand?

{$array['1a']} works fine for me with PHP 5.2.0.

I've also some weird problem where with $ signs.

$D['some_var']= '$19.99';

echo <<<content
$D[some_var]
content;

yields this: .99

Just looked at the php change log but it's a bit hard to parse!

It's a Blue Genesis server, not a great host, if you ask me!

is a number or a string based on the first character. In this case you
must still use single quotes around the '1a' - or PHP will try to
interpret it as a numeric index.

Just because you use heredoc doesn't mean you can get rid of *all*
quotes - just many of them. You still need to be aware of what's going on.

I find that a stand alone works as expected. In the code block itself
it fails. There's a bit of PDO before and not much else.

This is on the "special projects" server at Blue Genesis because they
don't run the MySQL PDO drivers on their normal server. I wouldn't be
surprised if there was a connection.

In fact, my "fix" for both bits is this:

foreach($D as $key=>$value){
$value = str_replace('$','',$value); // remove $
$D['x' . $key] = $value; // don't start index with a number
}

funky.

different in your code which is causing your problem (especially with
the fix you have).

But as it's part of a larger code base (which you don't show), it's hard
to tell just what is going on.
