voidappend
(string varname, mixed var, boolean merge)
This is used to append an element to an assigned array. If you append to a string value, it is converted to an array value and then appended to. You can explicitly pass name/value pairs, or associative arrays containing the name/value pairs. If you pass the optional third parameter of true, the value will be merged with the current array instead of appended.
添加指定的元素到数组中。如果是添加一个字符串,该字符串会被转换为数组格式后再进行添加。所添加的数据可以采用 名称, 数值 的格式,或者是使用 “=>”连接的联合数组格式。如果第三个可选参数被指定为 TRUE,所添加的数据会和数组中现有数据进行合并,而不是直接添加。
Technical Note:The merge parameter respects array keys, so if you merge two numerically indexed arrays, they may overwrite each other or result in non-sequential keys. This is unlike the array_merge() function of PHP which wipes out numerical keys and renumbers them.
注意:使用第三个参数“merge”时要考虑到数组的索 引,所以,如果添加和被添加的数组都是以数字为索引,他们会互相覆盖,或者产生不连续的索引。这并不象PHP中的array_merge()函数,后者会 删除原有的数字索引,重新对索引进行编号。
Example 13-1. append 例子 13-1. 添加
