我有自己的PHP函数有这个错误[关闭]

I have this function: 

function OUTconf($conf_name){
    $sql = mysql_query("SELECT CONF_VALUE FROM ".prefix."CONFIG WHERE CONF_NAME='".$conf_name."'") or die(mysql_error());
    $rs  = mysql_fetch_assoc($sql);
    $val = $rs['CONF_VALUE'];
    return $val;
}

and I have this html form:

<html>
<head>
    <title> <? OUTconf("SITE_TITLE"); ?> </title>
</head>
<body>
<? echo 'hello !!'; ?>
</body>
</html>

but when i test the code i got this error:

Fatal error: Cannot redeclare outconf() (previously declared in C:\AppServ\www\pv\includes\functions.php:13) in C:\AppServ\www\pv\includes\functions.php on line 18


can anyone help me?

    Fatal error: Cannot redeclare outconf() (previously declared in C:\AppServ\www\pv\includes\functions.php:13) in C:\AppServ\www\pv\includes\functions.php on line 18

    This means that functions.php is trying to declare the function OUTconf() while it's already declared (by the same script).

    Most probably you are including functions.php twice. Try using include_once instead of include.
