            [cat_id] => 172

Answer 1

Use end() .

$lastMember = end($arr);

Note that this advances the array's internal pointer, which may matter dependent on what other code you have.

Answer 2

您可以像这样检索数组的最后一个元素： $array[count($array) - 1]

Answer 3

您可以这样获得最后一个cat_name值：

$arr[count($arr) - 1]['cat_name']
