php实现通用的从数据库表读取数据到数组的函数实例

function listmytablerows($table, $name, $field, $where, $textid)
{
/ / connect to the database and query execution
connect ();
$sql = "select * from". $table. "". $where. "order by". $field;
$req = mysql_query($sql);
$res = mysql_num_rows($req);
?>
<select name = "<?php echo $name; ?>" id="<?php echo $textid; ?>">
<option value=""> ____</ option>
<? php
/ / we do a loop that will read the information for each record
while ($data = mysql_fetch_array($res))
{
  / / we display the information from the current record
?>
   <option value = "<?php echo $data['id']; ?>">
   <?php echo $data[$field]; ?>
</ option>
   <? php
  }
?>
</ select>
<? php
}
?>
