在这种情况下，请查看PHP是否支持此功能并且使用函数或扩展替代它。

So either you can use this to invoke the XML service directly and wait for the response, or you can pass in a function which will be invoked with the response XML.
于是您可以使用该函数直接调用XML服务，并且等待响应，或者您也可以传送一个函数，使用XML响应消息调用该函数。
To keep administrators or developers from constantly having to modify a script to work a certain way with other values, use variables and supply arguments to the script or function.
这迫使管理员或开发人员不得不经常修改脚本以使用其他值；为了避免这个问题，应该使用变量并为脚本或函数提供参数。
You can still use this function in an expression to determine if a particular built-in or extension function is supported as the stylesheet element is being processed.
仍然可以在表达式中使用该函数，确定在处理样式表元素的过程中处理程序是否支持某种内置的或扩展的函数。
Users can use the function to see new ways search results are linked, such as through timelines or a "Wonder Wheel," which displays visual relationships between search terms.
用户可以使用这个功能看到搜索结果的新的关联方式，比如可以通过时间表或者“大转盘”，这样可以可视化的显示搜索项之间的关系。
Being bilingual or learning languages preserves brain function and lowers the risk of dementia, and the "use it or lose it" theory also has proven benefits.
使用双语或学习语言可以保持大脑功能，降低痴呆症的风险，同时“不用则废”理论也已经证明了其好处。
Unfortunately, requirements are often automatically identified with user requirements, such as the function related to a use case or the response time requested for a specific operation.
不幸的是，需求通常会自动识别为用户需求，例如与特定运营所请求的用户或响应时间相关的功能。
A function may use as little or as much memory in this save area as needed.

Once the package is created, use the import function to bring in your COBOL or C files.

To use trap, you specify the command or function to be executed when the signal is trapped, and the signal number or Numbers that you want to trap, as shown here in Listing 13.
要使用跟踪，可以指定跟踪到信号时执行的命令或函数、要跟踪的信号编号，如此处的清单13中所示。
So, if you want to know if something is a maximum or a minimum, you just have to use common sense or compare the values of a function at the various points you found. Yes?
如果想知道是极大值还是极小值，那就只需用常识，或者直接比较各点的函数值？
This provides ease of use and avoids the need for you to re-enter the values during each run of the procedure or function.
这提供了方便性并避免了在每次运行过程或函数时重新输入值的麻烦。
Each time you use such a function or test, the data set must be sorted by the counted column before the occurrences of the values can be counted.
每次使用函数或者测试时，必须依照所计数列对数据集进行排序。
OK, so last time we saw how to use Lagrange multipliers to find the minimum or maximum of a function of several variables when the variables are not independent.
上次我们看了，怎样利用拉格朗日算子，去求解一个受约束的，多变量函数的最大最小值。
To have them sorted as Numbers, use number or a casting function.
如果要作为数字排序，使用number或者类型转换函数。
In fact, I'd say it's a must that any page that creates page elements dynamically, whether through Ajax or user interaction, must use the live function instead of the alternative event methods.
事实上，我认为它对于任何动态地创建页面元素的页面都是必不可少的，不管是通过Ajax还是用户交互进行创建，都需要使用live函数而不是事件方法。
You can use Boost static assertions in a class, function, or namespace scope; you can also use them with templates.
您可以在类、函数或命名空间范围中使用Boost静态断言；还可以与模板一起使用它们。
No matter where you declare a variable or function, the extern keyword allows other files to use it without knowing where it was defined.
不管在哪里声明一个变量或函数，extern关键字都允许其他文件在不确定其定义位置的情况下使用该文件。
However, if the program does not use gethostbyname or any other function that returns information in the same object, or if it always blocks signals around each use, you're safe.
不过，如果程序不使用gethostbyname或者任何其他在同一对象中返回信息的函数，或者如果它每次使用时都会阻塞信号，那么就是安全的。
In this article, PHP will be the server-side language and MySQL will be the database, although you don't need to use any specific server-side language or database to create this function.
在本文中，服务器端语言是PHP，数据库是MySQL，您不需要使用任何特定的服务器端语言或者数据库来创建此函数。
If a script invokes the functions or class methods of other Jython modules, use the execfile function to load a Jython script from another Jython script file. Listing 3 shows an example.
如果某个脚本调用其他Jython模块的函数或类方法，则使用execfile函数加载来自其他jython脚本文件的jython脚本。
Now modules can use the hook_profile_alter function to add, remove, or modify form elements in the user profile page.
现在，模块可以使用hook _ profile_alter函数在用户配置页面上添加、删除或修改表单元素。
For probe managers that support function entry or exit probes, the location field (the last field) must use the "entry or" exit keyword.
对于支持函数进入或退出探测的探测管理器，位置字段(最后一个字段)必须使用“entry”或“exit”关键字。
For probe managers that support function entry or exit probes, the location field (the last field) must use the "entry or" exit keyword.
