Editor to share with you how to use the array_column () function in php, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The use of the function array_column ()

$array = [['id'= >' 99', 'name'= >' 99'], ['id'= >' 88', 'name'= >' 88'], ['id'= >' 77', 'name'= >' 77'],]; $arr1 = array_column ($array, 'name') / output: array (0 = >'99', 1 = >'88', 2 = >'77',) $arr2 = array_column ($array, 'name',' id'); / / output: array (99 = >'99', 88 = >'88', 77 = >'77',)

Array_column () is used in conjunction with array_combine ()

$ids = array_column ($array, 'id'); $arrayCombine = array_combine ($ids, $array) / * $arrayCombine output: array (99 = > array ('id' = >' 99', 'name' = >' 99',), 88 = > array ('id' = >' 88', 'name' = >' 88',), 77 = > array ('id' = >' 77', 'name' = >' 77',) * / above are all the contents of the article "how to use the array_column () function in php" Thank you for reading!
