我正在尝试运行一个PHP页，该页应在我的MSSQL表“用户”中插入用户名和密码。当我运行页面时，唯一出现的错误是：

Warning: mssql_query() [function.mssql-query]: message: 'md5' is not a recognized built-in function name. (severity 15) in D:\Hostins0\html\insertadminaccount.php on line 10

Warning: mssql_query() [function.mssql-query]: Query failed in D:\Hostinstml\insertadminaccount.php on line 10
'md5' is not a recognized built-in function name.

这是我完整的PHP页面代码：

<?php
$conn=mssql_connect('sm','Gaer','Ra1!');
mssql_select_db('Gser',$conn);
if(! $conn )
{
  die('Could not connect: ' . mssql_get_last_message());
}
   $sqla = "INSERT INTO users (username, password)
VALUES ('rob_dewar01', " . md5 ('KingDozer') . ")";
mssql_query($sqla, $conn) or die(mssql_get_last_message());

if (!mssql_query) {
    // The query has failed, print a nice error message
    // using mssql_get_last_message()
    die('MSSQL error: ' . mssql_get_last_message());
}

mssql_close($conn);
?>

感谢您的任何帮助。感谢所有帮助。
