PHP天然就对MySQL有良好的支持,但是想要用PHP对SQL Server进行操作,则需要花点时间了。今天刚好团队里的一个项目需要用PHP对SQL Server进行操作,遂帮忙配置好环境。
首先说明下,服务器的系统版本为SUSE Linux Enterprise Server 10 SP3。
1. 安装FreeTDS
地址:FreeTDS
wget http://ibiblio.org/pub/Linux/ALPHA/freetds/stable/freetds-stable.tgz
tar zxvf freetds-stable.tgz
cd freetds-0.82
./configure --prefix=/usr/local/freetds --with-tdsver=8.0 --enable-msdblib --enable-dbmfix
make && make install
成功安装完,最好更新下动态连接库缓存:
echo "/usr/local/freetds/lib" >> /etc/ld.so.conf
ldconfig
2. 配置FreeTDS及连接测试
FreeTDS的配置文件放在安装目录的etc里,根据第一步的configure参数,我们FreeTDS安装在/usr/local/freetds:
vim /usr/local/freetds/etc/freetds.conf
由于不太清楚FreeTDS的具体有哪些可配置项,这里就不深入了,但是提供个比较重要的配置,用来解决中文乱码的问题。在配置文件添加如下语句:
client charset = utf8
然后,我们使用tsql命令测试下是否能正常连接上SQL Server数据库:
cd /usr/local/freetds/bin
./tsql -H 192.168.0.254 -p 1433 -U sa -P 123456
正常连接的话应该显示如下语句:
locale is "zh_CN.UTF-8"
locale charset is "UTF-8"

3. 安装php的mssql扩展
服务器上的php版本为5.3.13,php已安装在/usr/local/services/php下,扩展的目录为/usr/local/services/php/extensions。下面是安装mssql扩展的方法:
cd php-5.3.13/ext/mssql/
/usr/local/services/php/bin/phpize
./configure --with-php-config=/usr/local/services/php/bin/php-config --with-mssql=/usr/local/freetds
make #生成扩展文件,放在当前目录的module文件夹下
cp modules/mssql.so /usr/local/services/php/extensions/ #把扩展文件复制到PHP的扩展目录下
4. 配置php.ini并验证安装结果
打开php.ini,添加如下扩展语句:
extension=mssql.so
重启PHP服务后(服务器用的是php-fpm),打印phpinfo,出现如下配置则代表php能正常操作SQL Server了。

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
