I'm trying to pass a string variable to a custom function, echoing its
*value on one line, and its *name (that is, its key if this were an array
instead of a string) on another line. I searched the manual's sections on
variable functions and string functions, to no avail. I tried key(), but
it just produces a warning that $var is not an array. Example:
build_select_menu($display,array("Y","N"));
function build_select_menu($field,$options_array)
{
echo '<p><SELECT NAME="' . key($field) . '">' . "\n"; //need to echo
name of string passed as first argument
foreach($options_array as $option)
{
echo '<OPTION VALUE="Y"';
if($field=="$option") {echo ' SELECTED';}
echo ">$option</OPTION>\n";
}
echo "</SELECT></p>\n";
}
Thanks!
