对于其他php扩展，要验证Xdebug是否安装并可用，可以创建一个简单的骨架php程序来调用phpinfo并查看结果。
XDebug is something akin to a software X-ray: it peers into your application, exposes its inner workings, and reveals how your code spends its cycles.
XDebug是类似于软件x光照片的内容：它将深入应用程序，揭露内部工作原理，并且揭示代码如何度过其周期。
However, because xdebug is intended for use during development and assuming that the path to xdebug.so is correct, disable other extensions and retry.
但是，由于xdebug适于在开发时使用并假定xdebug . so的路径正确，因此需要禁用其他扩展并重试。
Xdebug intervenes after 49 function calls and yields Figure 2. (By the way, the initial invocation of main to launch the program counts as the first frame.)
Xdebug将在49次函数调用后介入并得到图2(顺便说一句，main的初始调用用于启动程序计数作为第1次调用)。
The directives (in the far left column in the large table in Figure 1) are just some of the parameters you can set to alter the behavior of the Xdebug extension.
指令（图1 中大表的最左侧一列）是一些可以设定的参数，用于改变Xdebug 扩展的行为。
