Create array using range function

The content of this article is about using the range function to create arrays. It has certain reference value. Now I share it with you. Friends in need can refer to it

Array traversal language


--Quickly create an array
--range(1,5)


What does this range function mean? Who is the key? Who is worth it? Range is a


function that quickly creates arrays. The functions provided by PHP to quickly create arrays include range(), explode(),
array_combine(), array_fill() and array_pad(). Don't understand the rest of the functions


. Focus on the range() function.


Syntax format, arrge range(mixed start,mixed end)
Function function: Quickly create a numeric array or character array ranging from start to end.
Note that if start>end, the sequence will be in descending order from start to end.
Come, let’s give an example,

1 [1]=>2 [2]=>3 [3]=>4 [4]=>5)
*前面是键，后面是值
/*
//如果是字符串怎么办？就不是数字了
$chars1 = range（'a','d'）;//chars是字符。开始序列是a，结束序
列是d
print_r($chars1);
/*输出数组里面的值。
*array( [0]=>a [1]=>b [2]=>c [3]=>d)
*/
?>

Summary, create an array, and then traverse the array. The limitation can only be a regular sequence. If there are no


rules, there is nothing you can do.
