[PHP] Name of an array???

[Dallas K.]

I need to echo the NAME of an array to the browser. when I try this all I get is 
Array. when I try to : echo $$array_name; I get nothing.

How can I get the NAME of an array to the browser?

Thanks.

Not quite sure what you're getting at here. As you discovered, if you have

$Thing = array(5,6,7,8);

and you 'echo $Thing;' you get 'Array.' However, in this case, you 
know the variable name already - $Thing!

Are you thinking more along these lines:

$ArrayName = 'Thing';
$$ArrayName = array(5,6,7,8);

now,

echo $ArrayName;== Thing
echo $$ArrayName;   == Array
echo ${$ArrayName}[0];  == 5

See

http://www.php.net/manual/en/language.variables.variable.php

for more info.
