Alan 的 web 开发历程. 有个朋友要在ssl加密的情况下(无需客户端证书)，PHP作为客户端用CURL库访问远程服务器，始终无法获得任何返回值，代码如下. Ch = curl init("https:/ ebs.95559.com.cn/") ;. Curl setopt($ch, CURLOPT RETURNTRANSFER, true) ;. Curl setopt($ch, CURLOPT FOLLOWLOCATION, true);. Curl close ($ch);. 换一个无ssl的网站，则一切正常，后来解决了，仅加一个选项即可：. Curl setopt($ch, CURLOPT SSL VERIFYPEER, false);. 如果没有仅仅是GET远程服务器上的内容，用fopen()既可，不过需要安装openssl扩展，否则提示. Unable to find the socket transport "https" - did you forget to enable it when you configured PHP? 160; {. 160; &#160...

Alan 的 web 开发历程. 最近在做一个遗留项目的维护，发现大量反模式被应用到该项目中，例如一个类数千行，构造函数的参数也是数十个，全局变量随处定义随处使用，没有规则和任何预期征兆的include。这真令人沮丧。某处用到的一个变量，不知道他是什么含义做何种控制之用；于是我想查找它是在哪里定义，在哪些地方有进行了重新赋值，以试图找到它的真实含义，可是我发现这是在有点难，因为通过文件内容搜索得出的结果往往有较多的冗余，而且没有安排好执行的先后顺序。在就在此时，我订阅的PHPe blog[ http:/ phpe.net/2010/10/php5-debugconsole/]刚好及时的介绍了这样一个优秀小工具[debugconsole http:/ www.debugconsole.de]，十分好用。根据官方网站提供的范例可以看出，结合PHP的declare语句使用，可以清楚打印出变量在哪些地方被改变（文件及行数），十分方便：. Require once './debugConsole.php';. Declare (ticks = 1);. Foo = '1';. Bar = $foo;.
