我freetds.conf如何使用FreeTDS連接到Sybase？
# /usr/local/etc/freetds.conf
# $Id: freetds.conf,v 1.12 2007/12/25 06:02:36 jklowden Exp $
#
# This file is installed by FreeTDS if no file by the same
# name is found in the installation directory.
#
# For information about the layout of this file and its settings,
# see the freetds.conf manpage "man freetds.conf".
# Global settings are overridden by those in a database
# server specific section
[global]
# TDS protocol version
; tds version = 4.2
# Whether to write a TDSDUMP file for diagnostic purposes
# (setting this to /tmp is insecure on a multi-user system)
dump file = /tmp/freetds.log
; debug flags = 0xffff
# Command and connection timeouts
; timeout = 10
; connect timeout = 10
# If you get out-of-memory errors, it may mean that your client
# is trying to allocate a huge buffer for a TEXT field.
# Try setting 'text size' to a more reasonable limit
text size = 64512
# A typical Sybase server
[egServer50]
host = symachine.domain.com
port = 5000
tds version = 5.0
# A typical Microsoft server
[egServer70]
host = ntmachine.domain.com
port = 1433
tds version = 7.0
[myserver]
host = myserver.com
port = 5000
tds version = 5.0
我sybase.php：
<?php
$server = 'myserver';
$user = 'user';
$pwd = 'pwd';
$db = 'db';
@sybase_connect($server, $user, $pwd) or die('Cannot connect');
echo "OK\n";
，當我跑它通過CLI，php sybase.php它工作得很好。但是當我通過網絡服務器運行它時，它不會連接。 有沒有人知道我的代碼有什麼問題？
我也試圖把
putenv("FREETDSCONF=/usr/local/etc/freetds.conf");
，但什麼也沒有發生，我甚至試圖把錯誤的路徑freetds.confsybase_connect()之前，代碼仍然運行良好（使用php sybase.php但不是通過Web服務器）。
順便說一句，我得到了這些錯誤，每次我重新啓動我的Apache：

我沒有取消註釋;extension=php_sybase_ct.dll在我php.ini，因爲我在我的Linux工作。我檢查了我的phpinfo()，我可以在其中看到sybase_ct部分。我使用這些參數構建了我的PHP：
