基于值重复的PHP拆分数组[关闭]

Question

Here is an example array I want to split:

(1,2,3,4,5,0,6,7,0,8,9,10,11,12,0)

How do I split it in 3 arrays like this?

(1,2,3,4,5,0) (6,7,0) (8,9,10,11,12,0)

Answer 1

Here's the solution. (Author said he wants to split at '0' instead of duplicate values)

function split_array_by_duplicate_values($a, $duplicate = 0)
{
    $c = array_intersect($a, array($duplicate));
    $r = array();
    $i = 0;
    foreach($c as $k => $v) {
        $l   = ++$k - $i;
        $r[] = array_slice($a, $i, $l);
        $i   = $k;
    }

    return $r;
}

$a = array(1,2,3,4,5,0,6,7,0,8,9,10,11,12,0);

print_r(split_array_by_duplicate_values($a));

returns

Array
(
    [0] => Array
        (
            [0] => 1
            [1] => 2
            [2] => 3
            [3] => 4
            [4] => 5
            [5] => 0
        )

    [1] => Array
        (
            [0] => 6
            [1] => 7
            [2] => 0
        )

    [2] => Array
        (
            [0] => 8
            [1] => 9
            [2] => 10
            [3] => 11
            [4] => 12
            [5] => 0
        )
