如何使用PHP通过unixodbc和freetds连接MSQL

Question

如上一个问题所述，freetds和unixodbc都安装在Lion上并使用isql进行测试，我尝试使用PHP连接到MSSQL：

$connection = odbc_connect('SMS_GTWY', 'username', 'password');

但是，它返回：

PHP Warning:  odbc_connect(): SQL error: [iODBC][Driver Manager]Specified driver could not be loaded, SQL state IM003 in SQLConnect in testodbc.php line 3
[iODBC][Driver Manager]Specified driver could not be loaded

我该如何解决它？

附言 执行上述 PHP 后$ cat /tmp/odbc_trace输出：

** iODBC Trace file
** Trace started on Fri Dec 14 18:03:27 2012
** Driver Manager: 03.52.0607.1008

Answer 1

要解决此问题，请使用 FREETDSCONF 、 ODBCINI 和 ODBCINSTINI 设置 env：

<?php
  putenv("FREETDSCONF=/Users/ohho/.freetds.conf");
  putenv("ODBCINI=/Users/ohho/.odbc.ini");
  putenv("ODBCINSTINI=/Users/ohho/.odbcinst.ini");
  $connection = odbc_connect('SMS_GTWY', 'sms_gtwy', 'sms_gtwy');
?>
