您还需要统计数组中的元素个数，并将其保存在变量 $numstories中。
You also need to count the number of elements in the array and use a variable $numstories to contain the result.
count函数统计数组中的元素个数，所以在本例中 $elems应该等于3。
The count function counts the number of elements in an array, so you would expect $elems to equal 3 in the example.
清单10展示如何从一个数组中检索最后一个元素。
Listing 10 shows how you can retrieve the last element from an array.
此循环迭代这个数组并打印每一行，与它在命令行上所做的无异，只不过在每次打印后均强制使用一个xhtml断行元素。
The loop simply iterates through the array and prints each line as it would do on the command line, but enforcing an XHTML break-line element after each print.
这些 XHR对象保存在一个数组内，数组为每个表单分配一个数组元素。
The XHR objects are kept in an array that allocates one element for each form.
假设一次基准测试希望度量出访问某个数组元素所用的时间：这个任务应该不用创建数组。
Consider a benchmark that aims to determine the time it takes to access an array element: the task should not create the array.
如果每个数组的元素都需要被处理，而且数组间没有依赖关系，执行的计算任务之间也不需要通信，这样的话将是一个执行并行式计算的理想环境。
If the same processing is required for each array element, with no dependencies in the computations, and no communication required between tasks, we have an ideal parallel computing opportunity.
如果一个元素包含多个相同名称的子元素，这些子元素将转换为一个数组属性。
If an element contains more than one sub-element of the same name, those sub-elements will be turned into an array property.
如果这个数组的长度或者元素的索引对于客户端的逻辑来说是重要的，那么客户端将会失败。
If this array's length or element index is important to the client's logic, then the client will fail.
为绕过这个限制，我使用一个数据结构来为每个数组元素定义一个已命名指示符变量。
To get around this I use a data structure to define a named indicator variable for each array element.
第一部分，在水平方向放入单词非常简单—构建一个数组的数组，每个数组中有10个元素，用句点填充。
The first part, putting in the horizontal words, is pretty easy - build an array of arrays, 10 elements each, filled with periods.
因此，如果每个数组元素的长度都是8个字节，那么我们就可以使用8作为倍数。
Therefore, if each array element is 8 bytes long, you can use 8 as a multiplier.
因此这儿我们要做的第一件事，就是要显示元素，在这儿元素就是数组了对不对？，因为这个数组包含了两个数组。
So the first thing we'll do is, we'll print the element, in this case it will be a list right? Because it's a list with two lists in it.
一个数组中最多可以有64个不同的元素。
读取的结果以数组传入时，只需要用数组的元素个数去除以1000即可。
As the readings are passed in as an array, you simply need to divide 1000 by the number of elements in the array.
清单4中的代码首先定义一个数组，其中第一个元素是要执行的二进制文件的路径，其余元素充当命令行参数。
The code in Listing 4 first defines an array, with the first element being the path to the binary that is to be executed, and the remaining elements acting as the command-line parameters.
在c标准中，必须定义至少一个数组元素。
In standard C, at least one element of an array must be defined.
清单8显示创建一个数组然后向其中添加3个元素的示例。
Listing 8 shows an example of creating an array and then adding three elements to it.
如果这两个数组中的任何元素以该前缀开头，贡献器会创建一个相应的CCompletionProposal。
If any element of the two arrays begins with the prefix, the contributor creates a corresponding CCompletionProposal.
如图2所示，For each的第一个功能是嵌套映射，该映射包含处理每个数组元素中数据的命令。
As shown in Figure 2, the first is a nested map that contains the instructions to handle the data in each of the array elements.
hash索引常常使用一个数组来实现，数组中的每个元素是一个有固定大小的hashbucket，如图1所示。
A hash index is often implemented using an array where each element in the array is a hash bucket with a fixed size, as is depicted in Figure 1.
第二个数组中的每个元素都为第一个数组中的对应元素选择元素名称。
Each element in the second array chooses the element name for the corresponding element in the first array.
注意定义文件中type属性的值：元素映射到一个数组，嵌套的映射为简单字符串值。
Notice the values of the type attribute in this definition file: the element is mapped to an array, while the nested s are mapped to simple string values.
箭头表示了对第i个数组元素所进行的操作。
创建数组函数可以将两个数组连接或结合成一个，或向数组中增加元素，这取决于你自己的设定。
Depending on how you configure it, Build array concatenates, or combines, two arrays into one, or adds extra elements to an array.
例如，图7.23中的创建数组函数被设定用来结合两个数组和一个单个元素产生一个新的数组。
For example, the Build array function shown in figure 7.23 has been configured to concatenate two arrays and one element into a new array.
每个数组元素能存放一个数据的值。
一个数组他的元素标识出了指定的源可用的媒体的类型。
An array whose elements identify the available media types for the specified source type.
每个数组元素都包含了文件中的一行，并在末尾加上了换行符。
Each array element contains a line from the file, with newline still attached.
如果两个数组的长度和元素类型相同，那么它们相同。
Two array types are identical if they have identical element types and the same array length.
