session的问题！！！

fxb248 2005-04-22 10:48:48

我写了个简单的程序测试session，程序如下：
<html>
<title>无标题文档</title>
<body>
<?php
Session_start();
Session_register("mycount");
$mycount++;
echo "$mycount";
?>

</body>
</html>
错误如下：
Warning: session_start(): Cannot send session cookie - headers already sent by (output started at C:\Inetpub\wwwroot\2.php:4) in C:\Inetpub\wwwroot\2.php on line 5

Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at C:\Inetpub\wwwroot\2.php:4) in C:\Inetpub\wwwroot\2.php on line 5

Notice: Undefined variable: mycount in C:\Inetpub\wwwroot\2.php on line 7
sdff 1
Warning: Unknown(): Your script possibly relies on a session side-effect which existed until PHP 4.2.3. Please be advised that the session extension does not consider global variables as a source of data, unless register_globals is enabled. You can disable this functionality and this warning by setting session.bug_compat_42 or session.bug_compat_warn to off, respectively. in Unknown on line 0
请高手指点啊！！！

以下是我的代码是由DW插件做的.
<?php require_once('Connections/conn.php'); ?>
<?php
$colname_member = "1";
if (isset($HTTP_SESSION_VARS['MM_m_name'])) {
$colname_member = (get_magic_quotes_gpc()) ? $HTTP_SESSION_VARS['MM_m_name'] : addslashes($HTTP_SESSION_VARS['MM_m_name']);
}
mysql_select_db($database_conn, $conn);
$query_member = sprintf("SELECT * FROM memberdata WHERE m_name = '%s'", $colname_member);
$member = mysql_query($query_member, $conn) or die(mysql_error());
$row_member = mysql_fetch_assoc($member);
$totalRows_member = mysql_num_rows($member);

// *** Start the session
session_start();
// *** Validate request to log in to this site.
$FF_LoginAction = $HTTP_SERVER_VARS['PHP_SELF'];
if (isset($HTTP_SERVER_VARS['QUERY_STRING']) && $HTTP_SERVER_VARS['QUERY_STRING']!="") $FF_LoginAction .= "?".$HTTP_SERVER_VARS['QUERY_STRING'];
if (isset($HTTP_POST_VARS['m_name'])) {
$FF_valUsername=$HTTP_POST_VARS['m_name'];
$FF_valPassword=$HTTP_POST_VARS['m_passwd'];
$FF_fldUserAuthorization="m_level";
$FF_redirectLoginSuccess="12.php";
$FF_redirectLoginFailed="22.php";
$FF_rsUser_Source="SELECT m_name, m_passwd ";
if ($FF_fldUserAuthorization != "") $FF_rsUser_Source .= "," . $FF_fldUserAuthorization;
$FF_rsUser_Source .= " FROM memberdata WHERE m_name='" . $FF_valUsername . "' AND m_passwd='" . $FF_valPassword . "'";
mysql_select_db($database_conn, $conn);
$FF_rsUser=mysql_query($FF_rsUser_Source, $conn) or die(mysql_error());
$row_FF_rsUser = mysql_fetch_assoc($FF_rsUser);
if(mysql_num_rows($FF_rsUser) > 0) {
// username and password match - this is a valid user
$MM_Username=$FF_valUsername;
session_register("MM_Username");
if ($FF_fldUserAuthorization != "") {
$MM_UserAuthorization=$row_FF_rsUser[$FF_fldUserAuthorization];
} else {
$MM_UserAuthorization="";
}
session_register("MM_UserAuthorization");
if (isset($accessdenied) && false) {
$FF_redirectLoginSuccess = $accessdenied;
}
mysql_free_result($FF_rsUser);
session_register("FF_login_failed");
$FF_login_failed = false;
header ("Location: $FF_redirectLoginSuccess");
exit;
}
mysql_free_result($FF_rsUser);
session_register("FF_login_failed");
$FF_login_failed = true;
header ("Location: $FF_redirectLoginFailed");
exit;
}
