最近一个项目由"WinForm直接访问DB2"移植到"WinForm通过PHP Web Service来访问DB2”。
这个命题的难点不是访问DB2，而是.NET调用PHP Web Service。对于我这个长期作.NET，之前一直以为只有通过.NET调用PHP Web Service……的人来说，真是有点强“聪”所难了。
但是问题还是要解决的，期限就摆在眼前呢。经过一番调查，终于有了眉目，现在分享给大家。
首先要说明的，PHP服务器需要至少需要两个文件——一个WSDL文件和一个PHP文件。WSDL文件是一种机读的XML文件，用于描述WebService提供的服务和调用方法（对于.NET则可以自动生成调用代码，十分好用），php文件就是真正实现的WEB服务了。

WSDL的代码比较长，当方法很多时，手敲代码是不太可能的。有一个巧的办法，就是也用.NET实现一个不含真正方法体的Web Serivce,然后通过http://***/TestWebService.asmx?wsdl的方法生成wsdl代码文件。
关于WSDL文件，我要说明特别说明两点：
（1）soap:address结点是声明WebService的地址，在部署时要改成相应地址；
（2）一维数组的声明类型为ArrayOfType,字符串数组为ArrayOfString。如果Type不是简单类型，则Type需要另外声明。
2）.NET客户端代码
先要添加Web引用，地址为WSDL文件的Http地址。
.NET调用PHP Web Service调用代码（C#）
<ol class="dp-xml">
<li class="alt"><span><span>//初始化WebService </span></span></li>
<li>
<span> localhost.TestWebService </span><span class="attribute"><font color="#ff0000">srv</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">new</font></span><span> localhost.TestWebService(); </span>
</li>
<li class="alt"><span> //调第一个方法 </span></li>
<li>
<span> string </span><span class="attribute"><font color="#ff0000">str</font></span><span> = </span><span class="attribute-value"><font color="#0000ff">srv</font></span><span>.HelloWorld(); </span>
</li>
<li class="alt"><span> //调第二个方法 </span></li>
<li>
<span> string[] </span><span class="attribute"><font color="#ff0000">arry</font></span><span>= </span><span class="attribute-value"><font color="#0000ff">srv</font></span><span>.GetArray("string1","string2"); </span>
</li>
</ol>
.NET调用PHP Web Service总结：
（一）PHP是一种弱类型语言，检查错误比较困难。array类型也与一般理解的数组不同，它也有类似Hashtable的用法。
（二）PHP Web Service方法的传入参数、返回值都至多有一个，因为真正调用时的参数和返回值，都是包装到一个对象中传送的。
（三）PHP Web Service也支持自定义类型和自定义类型数组等复杂类型，但不支持多组数组。
（四）若返回值需要是多张二维表时，我浅薄的以为，可以传化一组字符串数组传送，格式为
[表1行数],[表1列数],[表1列名1]，[表1列名2],……[表1列名N]，[表1中按行列存放的值]
[表2行数],[表2列数],[表2列名1]，[表2列名2],……[表2列名N]，[表2中按行列存放的值]……
[表M行数],[表M列数],[表M列名1]，[表M列名2],……[表M列名N]，[表2中按行列存放的值]
按顺序将上面[]中的内容串成字符串数组,效率还不错,我测试10000行240列的数据,我有现成编解代码,有兴趣的可以向我索取.

超越炒作：评估当今PHP的角色Apr 12, 2025 am 12:17 AMPHP在现代编程中仍然是一个强大且广泛使用的工具，尤其在web开发领域。1)PHP易用且与数据库集成无缝，是许多开发者的首选。2)它支持动态内容生成和面向对象编程，适合快速创建和维护网站。3)PHP的性能可以通过缓存和优化数据库查询来提升，其广泛的社区和丰富生态系统使其在当今技术栈中仍具重要地位。
PHP中的弱参考是什么？什么时候有用？Apr 12, 2025 am 12:13 AM在PHP中，弱引用是通过WeakReference类实现的，不会阻止垃圾回收器回收对象。弱引用适用于缓存系统和事件监听器等场景，需注意其不能保证对象存活，且垃圾回收可能延迟。
解释PHP中的__ Invoke Magic方法。Apr 12, 2025 am 12:07 AM\_\_invoke方法允许对象像函数一样被调用。1.定义\_\_invoke方法使对象可被调用。2.使用$obj(...)语法时，PHP会执行\_\_invoke方法。3.适用于日志记录和计算器等场景，提高代码灵活性和可读性。
解释PHP 8.1中的纤维以进行并发。Apr 12, 2025 am 12:05 AMFibers在PHP8.1中引入，提升了并发处理能力。1)Fibers是一种轻量级的并发模型，类似于协程。2)它们允许开发者手动控制任务的执行流，适合处理I/O密集型任务。3)使用Fibers可以编写更高效、响应性更强的代码。
PHP社区：资源，支持和发展Apr 12, 2025 am 12:04 AMPHP社区提供了丰富的资源和支持，帮助开发者成长。1)资源包括官方文档、教程、博客和开源项目如Laravel和Symfony。2)支持可以通过StackOverflow、Reddit和Slack频道获得。3)开发动态可以通过关注RFC了解。4)融入社区可以通过积极参与、贡献代码和学习分享来实现。
PHP与Python：了解差异Apr 11, 2025 am 12:15 AMPHP和Python各有优势，选择应基于项目需求。1.PHP适合web开发，语法简单，执行效率高。2.Python适用于数据科学和机器学习，语法简洁，库丰富。
php：死亡还是简单地适应？Apr 11, 2025 am 12:13 AMPHP不是在消亡，而是在不断适应和进化。1)PHP从1994年起经历多次版本迭代，适应新技术趋势。2)目前广泛应用于电子商务、内容管理系统等领域。3)PHP8引入JIT编译器等功能，提升性能和现代化。4)使用OPcache和遵循PSR-12标准可优化性能和代码质量。
PHP的未来：改编和创新Apr 11, 2025 am 12:01 AMPHP的未来将通过适应新技术趋势和引入创新特性来实现：1)适应云计算、容器化和微服务架构，支持Docker和Kubernetes；2)引入JIT编译器和枚举类型，提升性能和数据处理效率；3)持续优化性能和推广最佳实践。
