SQL Server

提出问题前几天做了一个非常奇怪的项目，我公司开发了一套基于中国联通SGIP协议的SP端短消息服务软件，提供联通130短信服务。这套系统是Windows 2000下的，数据库采用的是微软SQLServer2000，并且已经正常运行了一段时间。而最近由于要在WEB上提供短消息用户的一些信息，就需要从WEB上读写SQLServer数据库，本来SQLServer数据库的最佳搭档应该是微软IIS ASP服务端脚本，但我公司一向认为IIS+ASP的稳定性和安全性都不尽如意，希望能够在Linux下用PHP脚本读写SQLServer。分析问题本来PHP脚本读写SQLServer是没有什么问题的，在Apache for windows和Windows IIS下可以工作的很好，一般可以通过ODBC或SQLServer Client连接，这都是Windows下面现成的。但是在Linux下面没有现成的ODBC和SQLServer Client，需要我们自己安装。解决问题一、相关软件 freetds 来源：ftp://ftp.ibiblio.org/pub/Linux/ALPHA/freetds/freetds-0.53.tgz 这个软件能够用Linux和Unix连接MS SQLServer和Sybase数据库。二、安装配置步骤第一步：编译安装freetds: 得到freetds-0.53.tgz后 cp freetds-0.53.tgz /tmp/. （拷贝freetds包到/tmp目录） cd /tmp （进入目录） tar zxvf freetds-0.53.tgz （解压） cd freetds-0.53 （进入解压后目录） ./configure –prefix=/usr/local/freetds --with-tdsver=7.0 gmake （生成Makefile，我试验过，make也可以） gmake install （安装）关于上面configure我想说一下，--prefix=/usr/local/freetds是指安装到/usr/local/freetds这个目录中，--with-tdsver=7.0是指安装tds 7.0版本（最开是我没有加这个编译参数，结果按照默认编译为5.0。5.0连接数据库的端口是4000，不是SQLServer的1433）第二步：重新编译PHP4 ./configure [--with-apxs --with-mysql...] --with-sybase=/usr/local/freetds（请注意是sybase） make make install 第三步:配置freetds vi /usr/local/freetds/etc/freetds.conf 具体配置见该文件中的说明例: （典型配置） [sqlserver] host = sql_server_name_or_host_ip （你的SQLServer机器名字或者IP地址） port = 1433 tds version = 7.0 在这个配置文件中可以配置Windows域登陆或者SQLServer账号登陆两种方式第四步:配置php.ini文件找到 ;extension=mssql70.so 将注释;去掉成 extension=mssql70.so 第五步:在php中建立数据库连接 $link=mssql_connect("sqlserver",$your_username,$your_password) or die (“can’t Connect to Database”); echo $link; 在浏览器中运行上面脚本，如果你得到一个link号那么恭喜，你已经配置好了，如果出现Call to undefined function: mssql_connect() 那说明仔细看上面的安装配置过程看你哪一步没有对。注意:sqlserver名称是在/usr/local/freetds/etc/freetds.conf中定义的host参数，如果你写的IP地址，就是IP地址。其他数据库操作参考相关mssql函数注意,在sql语句中不支持中文!!! 第六步：调试如果出现不能连接，请在freetds配置文件中找到;dump file = /tmp/freetds.log这一行，注释掉前面的分号，再执行一下测试脚本，察看/tmp/freetds.log文件，它可以告诉你很多出错的信息帮助你排除问题。

PHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AM

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP: Is It Dying or Simply Adapting?Apr 11, 2025 am 12:13 AM

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The Future of PHP: Adaptations and InnovationsApr 11, 2025 am 12:01 AM

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

When would you use a trait versus an abstract class or interface in PHP?Apr 10, 2025 am 09:39 AM

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

What is a Dependency Injection Container (DIC) and why use one in PHP?Apr 10, 2025 am 09:38 AM

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Apr 10, 2025 am 09:37 AM

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

How does PHP handle file uploads securely?Apr 10, 2025 am 09:37 AM

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?Apr 10, 2025 am 09:33 AM

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
