PHP function to automatically output the select form

The following functions are implemented: Automatically generate select options.

The code is as follows:

$item){ $str_sel=""; if($key==$msg_val) $str_sel=" selected"; $str_return.="".$item.""; } }else{ foreach($arr_list as $item){ $str_sel=""; if($item==$msg_val) $str_sel=" selected"; $str_return.="".$item.""; } } return $str_return; } ?>

Code description: Returns a select option item, $msg_list is an array ($key=>$value), $msg_val is the value that needs to be selected by default. The function can be written as a static method in a PHP static class, which is more convenient to use.
