How do you print the name of a variable?

[Marqis]

This is related to my other question 'including files from inside an eval'.

Anyhow, how do you print the name of a variable as opposed to the value of the variable?

Specifically, I want to write a function that prints out the $GLOBALS array and values.

Here's what I have so far (which doesn't work for crap):

function PrintArray($array)
{
global $endl;

foreach($array as $arr)
{

	if(is_array($arr))
	{
		print "<blockquote>".$endl;
			SimplePrintArray($arr);
		print "</blockquote>".$endl;
	}
	else
	{
	// want to print variable_name=$$arr
		print $arr.$endl;
	}
}
}

Another problem with this function is that when used on $GLOBALS it recurses forever, is there a way to stop that?

Thanks,
Marqis

Man, am I ever an idiot...

function PrintArray($array)
{
$endl="<br>\n";

foreach($array as $key=>$value)
{
	if(is_array($value) && $key != "GLOBALS")
	{
		print $key."<blockquote>".$endl;
			PrintArray($value);
		print "</blockquote>".$endl;
	}
	else
		print $key."=".$value.$endl;
}
}

Try the print_r() function, that's what it's for:

Opps, I didn't read the warning about $GLOBALS at the bottom of the page I posted. :eek:

Maybe print_r() (and var_dump()) should have an optional depth-limiting argument....
