Laravel，如何使用索引获取数组值？

Question

How do I get array values using their index, that is, using index 0 until 20 as shown in the picture below. I wanted to get the specific value, using index number 3 for example.

Answer 1

$my_array = [0,1,2,3,4,5,6,7,8,9,];

您需要数组编号5，因此请执行以下操作：

$data = array_keys($my_array, 5);

Answer 2

you can use :

foreach( $array as $index => $element )
{ 'show'. $index . '=>'. $element }

Answer 3

试试这个：假设您有$ data作为数组，并且要打印第3个元素，那么$ data [3]将给您第3个元素。
