PHP 的 Web Service Solution

昨天跟夢想家的 Emma 談到 Irose 前台改版成 PHP 的方案。

因為 Irose 採用 Mobocash 的 Web Service 來執行付款機制，但是 PHP 早期並沒有內建 SOAP ，必須透過一些 3rd Party 的程式來呼叫 Web Service。

另外好消息是 PHP5 已經有內建 SOAP extension，官方發佈消息如下:

Some of the key features of PHP 5 include:

• The Zend Engine II with a new object model and dozens of new features.
• XML support has been completely redone in PHP 5, all extensions are now focused around the excellent libxml2 library ( http://www.xmlsoft.org/ ).
• A new SimpleXML extension for easily accessing and manipulating XML as PHP objects. It can also interface with the DOM extension and vice-versa.
• A brand new built-in SOAP extension for interoperability with Web Services.
• A new MySQL extension named MySQLi for developers using MySQL 4.1 and later. This new extension includes an object-oriented interface in addition to a traditional interface; as well as support for many of MySQL’s new features, such as prepared statements.
• SQLite has been bundled with PHP. For more information on SQLite, please visit their website .
• Streams have been greatly improved, including the ability to access low-level socket operations on streams.

如果使用的是 PHP 4.3.0 以上，又不想用3rd Party的函式，可以參考這篇:

至於 PHP 早期的版本，比較有名的3rd Party 就屬 XML-RPC 跟 NuSOAP 了，XML-RPC 則是從 PHP 3 時代就能使用了，NuSOAP 目前到現在程式還是有在維護。
