Array is used as the parameter of the sort function, and after sorting, the array itself is changed, and the return value of the function is bool type. 2 function name appears single A association, meaning, in the process of ordering by value, maintain the key=>value of the corresponding relationship is unchanged 3 function name in a single K represents key, meaning, in the process of sorting by value according to the array key instead of the value of the array sort 4 The expression reverse o

List Lists are one of the most commonly used data types and can be easily stored, modified, and manipulated by the list. 1. Defining the list Fruits = [' apple ', ' banana ', ' orange '] 2. Use the subscript to access the elements in the list, and the subscripts count from 0 >>> fruits[0] ' Apple ' >>> fruits[2] ' orange ' >>> fruits[-1] ' orange ' >>> fruits[-2] ' Banana 3. Slicing >>> fruits = [' apple '

Selling combs to monks is just like selling ice to eskimoans and gas masks to deer in the forest. Selling all products that customers don't need seems impossible, for most salesmen, it is impossible to produce results. However, for sales promotion experts and sales elites, more acceptable is just a task that is similar to impossible to accomplish and a challenge to surpass themselves. What they want to accomplish is to turn fantasies into ideals, turn the ideal into reality and turn all impossib

To count array elements, you can use the count () function: $ NamesArray = array ("Joe", "Jane", "Bob", "Mary", "Paul", "Eddie", "John "); $ Count = count ($ namesArray);?> The $ count value is 7. You can add elements to any array, whether at the beginning or end of an existing array. You can also use a function to create a new array containing two or more array elements. During me

array is arranged in the order in which it is needed. If your array already has an internal sort, you need to reorder the new merged array. Let's start with adding elements to the end of an existing array, using the function Array_push (): Copy CodeThe code is as follows: /* Create original array */ $fruitArray = Array ("Apple", "orange", "banana", "kiwi", "pear"); /* Add to original array */ Array_push ($fruitArray, "Grape", "pineapple", "tomato")

array, or use array_merge () to create a new array containing two or more elements in the array, the order of elements is arranged in the specified order. If the original array is out of order, it needs to be re-ordered after merging. We can first use array_push () to add an element at the end of the array: $ Fruitarray = array ("apple", "orange", "banana", "Kiwi", "Pear "); /* Add elements to the array */ Array_push ($ fruitarray, "grape", "pineapp

The ordering of several array functions mentioned below has some commonality:The 1 array is used as the parameter of the sort function, and after sorting, the array itself is changed, and the return value of the function is bool type. 2 function name appears single A association, meaning, in the process of ordering by value, maintain the key=>value of the corresponding relationship is unchanged 3 function name in a single K represents key, meaning, in the process of sorting by value according to
