php - FreeTDS mssql_connect 不工作

Question

我有一个 UBUNTU LAMP 设置。安装了所有必要的扩展
php5-odbcphp5-mssqlFREETDSunixODBC
在 CLI 中，我使用 isql 测试了与数据库的连接。和 tsql两者都连接并完美运行。

这是我的freetds.conf :

    ....
    # A typical Microsoft server
[TS]
        host = 10.32.6.52
        port = 1433
        tds version = 8.0
        client charset = UTF-8

这是我的 odbc.ini

[TS]
Description = "XXXXXXX"
Driver = /usr/local/lib/libtdsodbc.so
Server = xxx.xxx.xxx.xxx
Port = 1433
Database = XX_X_XX_XXXXX
Trace = No
TDS_Version = 8.0
[Default]
Driver=/usr/local/lib/libtdsodbc.so

这是我的 odbcinst.ini

[FreeTDS]
Description = FreeTDS
Driver = /usr/lib/x86_64-linux-gnu/odbc/libtdsodbc.so
Setup = /usr/lib/x86_64-linux-gnu/odbc/libtdsS.so
FileUsage = 1
CPTimeout =
CPResuse  =
client charset = utf-8
UsageCount = 1

这是我的php

<?php

putenv("TDSVER=80");
putenv("FREETDSCONF=/etc/freetds/freetds.conf");
putenv("ODBCSYSINI=/etc/odbcinst.ini");
putenv("ODBCINI=/etc/odbc.ini");


$myServer = "XXX.XXX.XXX.XXX";
$username = "XXXXX";
$password = "XXXXX";
$database = "XXXXX";

//connection to the database
$dbhandle = mssql_connect($myServer, $username, $password)
  or die("Couldn't connect to SQL Server on $myServer");

//select a database to work with
$selected = mssql_select_db($database, $dbhandle)
  or die("Couldn't open database $myDB");

//declare the SQL statement that will query the database
$query = "SELECT title from project where id = 8 ";

//execute the SQL query and return records
$result = mssql_query($query);

$numRows = mssql_num_rows($result);
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>";

//display the results
while($row = mssql_fetch_array($result))
{
  echo "<li>" . $row["title"] . "</li>";
}
//close the connection
mssql_close($dbhandle);
?>

就像我在 CLI 中所说的那样，我可以连接到 SQL 服务器，但从 php 中它不起作用。我已经尝试了所有我能找到的建议，但对我没有任何帮助。

我的 Apache 错误日志也可供引用:

发现问题并解决。我通过取消注释 /etc/freetds/freetds.conf 中的日志文件位置来启用 Freetds.log

这是日志文件提取

config.c:303:[XXXXXXXXX] not found.
config.c:367:... $FREETDS not set.  Trying $HOME.
config.c:293:Could not open '/var/www/.freetds.conf' ((.freetds.conf)).
config.c:297:Found conf file '/usr/local/etc/freetds.conf' (default).
config.c:483:Looking for section global.
config.c:542:   Found section global.
config.c:545:Got a match.
config.c:567:   text size = '64512'
config.c:542:   Found section egserver50.
config.c:542:   Found section egserver70.
config.c:556:   Reached EOF
config.c:483:Looking for section XXXXXXXXXXXX.
config.c:542:   Found section global.
config.c:542:   Found section egserver50.
config.c:542:   Found section egserver70.
config.c:556:   Reached EOF
config.c:303:[XXXXXXXXXXXX] not found.
config.c:208:Failed in reading conf file.  Trying interface files.
config.c:1042:Looking for server XXXXXXXXXXX....

所以基本上它是在 freetds.conf 文件中寻找我的服务器名。但我没有具体说明。连接信息在配置文件中列为 [TS]我更改了我的 php 信息以查找 [TS]突然之间它起作用了

$myServer = "TS";
$username = "XXXXX";
$password = "XXXXX";
$database = "XXXXX";
