[請益] 是ob使用方式錯誤還是我的寫法不對?
請問一下各位大大
以下是我用dw做的,由於測試的時候會顯示
Warning: session_start() [function.session-start]: Cannot send session cookie
- headers already sent by (output started at C:\AppServ\www\login.php:1) in
C:\AppServ\www\login.php on line 92884792
Warning: session_start() [function.session-start]: Cannot send session cache
limiter - headers already sent (output started at C:\AppServ\www\login.php:1)
in C:\AppServ\www\login.php on line 1450498949
我就在session_start()這區塊使用緩衝ob_start()跟ob_end_flush()
但是最後還是出現一樣的錯誤
不知道是不是我的緩衝使用錯誤...
而爬文後也找到程式砍掉文件內的bom了
php.ini也修改過了=>info.php顯示output_buffering的值為1
伺服器也重開過了
另外google過一些資料發現也有些人有相同情況
有些回答的人指出
網頁頂端這行<?php virtual('/Connections/ezchange.php'); ?>
可能會有輸出的動作造成底下header的執行出錯
也試過將ob放在不同地方,但是有時候測試一出錯整個伺服器就掛掉需要重啟
以下是程式碼的部份...不知道到底是哪裡有問題呢?
<?php virtual('/Connections/ezchange.php'); ?>
<?php ob_start();?><?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "",
$theNotDefinedValue = "")
{
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
$theValue = function_exists("mysql_real_escape_string") ?
mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" :

break;

$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}

補完整一點...BOM我應該有用爬文的方法砍了說
再次執行他都會顯示找不到含有BOM的文件...
