Is there a way to get a variable name as a string?

Is there a way to get the name of a variable as a string? For example... Function myname ($foo) { echo "the variable name passed in is ".realname($foo); } myname($bar); ^^^^ I want to see printed out: "the variable name passed in is bar" ^^^ Dig what I'm trying to do? And 'why?' you may ask am I trying to do this... Well, I am sick of always putting an "echo 'printing out bar:'; print_r($bar);" all the time. I want to make a wrapper function. I also have written one for XML that would be nice to make a NAME='bar' attribute... /** * Print out an array in XML form (useful for debugging) * @access public * @author Daevid Vincent [daevid@daevid.com] * @since 4.0b4 * @version 1.0 * @date 07/18/05 */ function print_r_xml($myArray) { print xmltag('ARRAY', array('NAME'=>'myArray'), 1); foreach($myArray as $k => $v) { if (is_array($v)) print_r_xml($v); else print xmltag($k,htmlspecialchars($v)); } print xmltag('ARRAY', null, 2); }
