初试PHP连接sql server

最开始想使用 pdo_sqlsrv 拓展，但是一直没成功，本文采用的是 pdo_dblib + freetds。

环境：CentOS 6.8、PHP 5.6.20

freetds

 wget ftp://ftp.freetds.org/pub/freetds/stable/freetds-1.00.109.tar.gz
 tar -xzf freetds-1.00.109.tar.gz
 cd freetds-1.00./
 ./configure --prefix=/datas/soft/freetds  --enable-msdblib  --with-tdsver=7.1
 make
 make install
 /datas/soft/freetds/bin/tsql -C

pdo_dblib

 cd ~/php-5.6./ext/pdo_dblib
 /datas/soft/php56/bin/phpize
 ./configure --with-php-config=/datas/soft/php56/bin/php-config --with-pdo-dblib=/datas/soft/freetds
 make
 make install
 vim /datas/soft/php56/etc/php.ini
     extension = "pdo_dblib.so"
 php --ri pdo_dblib

测试代码

 $db = new PDO ("dblib:host=IP:端口;dbname=数据库名","用户名","密码");
 $stmt = $db->prepare("SELECT top 5 * FROM my_table");
 $stmt->execute();
 while ($row = $stmt->fetch()) {
     var_dump($row);
 }

另外，我这边用的是 php-5.6.20 安装包里自带的拓展包去编译 pdo_dblib，偶然有一次是从 http://pecl.php.net/package/PDO_DBLIB 下载的，会出现以下错误

 checking for re2c... no
 configure: WARNING: You will need re2c 0.13. or later if you want to regenerate PHP parsers.
 checking for gawk... gawk
 checking for PDO_DBLIB support via FreeTDS... yes, shared
 configure: error: Directory /datas/soft/freetds is not a FreeTDS installation directory
