讨论一个有趣的问题，PHP手册为什么把待搜索的数组叫做$haystack呢？？？
mixed array_search ( mixed $needle , array $haystack [, bool $strict ] )
查的字典，haystack中文意思是干草堆，为什么用这个词来命名呢？是因为待选数组就想一堆干草堆一样，是每个元素拼凑到一起的吗？
很有趣，大家一起讨论讨论！
------解决方案--------------------
可以这么理解啊。

从一堆干草(haystack)里找出一根针(needle)，不是很形象吗亲？

哈哈是啊是啊！

Simple and clear method to use PHP array_merge_recursive() function
Jun 27, 2023 pm 01:48 PM
When programming in PHP, we often need to merge arrays. PHP provides the array_merge() function to complete array merging, but when the same key exists in the array, this function will overwrite the original value. In order to solve this problem, PHP also provides an array_merge_recursive() function in the language, which can merge arrays and retain the values of the same keys, making the program design more flexible. array_merge

How to convert LinkedList to Array in Java?
Aug 29, 2023 pm 11:09 PM
The toArray() method of the LinkedList class converts the current LinkedList object into an array of object type and returns it. This array contains all the elements in this list in correct order (from first element to last element). It acts as a bridge between array-based and collection-based APIs. So, convert LinkedList to array - instantiate LinkedList class. Populate it using the add() method. Call the toArray() method on the linked list created above and retrieve the array of objects. Converts each element of an array of objects to a string. Example Real-time demonstration of importjava.util.Arrays;importjava.uti
How to use the Array module in Python
May 01, 2023 am 09:13 AM
The array module in Python is a predefined array, so it takes up much less space in memory than a standard list, and can also perform fast element-level operations such as adding, deleting, indexing, and slicing. In addition, all elements in the array are of the same type, so you can use the efficient numerical operation functions provided by the array, such as calculating the average, maximum, and minimum values. In addition, the array module also supports writing and reading array objects directly into binary files, which makes it more efficient when processing large amounts of numerical data. Therefore, if you need to process a large amount of homogeneous data, you may consider using Python's array module to optimize the execution efficiency of your code. To use the array module, you first need to
