[RESOLVED] foreach()

[snomuse]

funny this seems to work else where in my code but for some reason this is happening:

Warning: Invalid argument supplied for foreach() in /home/xxxx.org/htdocs/music/order_form/includes/html_table.class.php on line 19

Here is the code, line 19 is the foreach() line:

private function addAttribs( $attr_ar ) {
    $str = '';
    foreach( $attr_ar as $key => $val ) {
		$str .= " $key=\"$val\"";
    }
    return $str;
}

Am I missing something simple? I must be. Thanks for looking.

Sounds like the $attr_ar parameter being passed in isn't an array. [man]var_dump/man will give you plenty of debugging information about a variable - try starting with that.

I will have to go over some debugging techniques.
Thanks for the point in the right direction.
