How to reference the key value in an array???

Howdy... 🙂

I have this array $x which has five fields in it... (Please correct me if I am not using the right term...)

<?php

$x = array("a" => array("a1","a2","a3")
	  ,"b" => array("b1","b2")
	  ,"c" => array("c1","c2","c3")
	  ,"d" => array("d1","d2","d3")
	  ,"e" => array("e1")
	  );

foreach ($x as $key)
{
	echo '<li>' . $key;
	foreach ($key as $subkey)
	{
		echo '<li>' . $subkey;
	}
	echo "<BR>---";
} 

?>

The echo lines displays this output...

Array
a1
a2
a3
---
Array
b1
b2
---
Array
c1
c2
c3
---
Array
d1
d2
d3
---
Array
e1
---

Each line displays 'Array' but I want to display the actual value(a, b, c, d, e) there...
What's the right syntax to reference the field in the array???

Thank you...

Oh... This worked... 🙂

foreach ($x as $field=>$key)
//
echo '<li>' . $field;
