[Mapserver-users] listing field names of my $oShape->values; (Because it's Friday???)

[Dylan Keon]

Denis,

$oShape->values is an associative array.  Asking for $flds[$fieldcount] 
will give you nothing since the keys are not a numeric index.

Try replacing your "for" loop with this:

	foreach($oShape->values as $key=>$value) {
		echo "$key = $value<br>\n";
	}

Just echo $key to get the field names only.
