$test = "Hello World!";
function showvar($var) {
foreach($GLOBALS as $key => $value) {
if($value == $var) {
$varname = $key;
}
}
echo "Variable Name: ".$varname."<br>\n";
echo "Variable Value: ".$var."<br>\n";
}
showvar($test);
This is the only thing that works for me.....I know it is messy

This is a bit kludgy, but should work:
function showvar($varname) {
if (!isset($GLOBALS[$varname])) { return; }
echo "Now showing: $varname\n";
echo "Value: ".$GLOBALS[$varname]."\n";
}
$s1 = "Hello World";
showvar('s1');
