具有自定义格式的内爆数组

Question

我有这种形式的数组

Array
    (
        [0] => 8
        [1] => 2
        [2] => 10
        [3] => 11
        [4] => 19
        [5] => 13
        [6] => 10
    )

我想将值内爆到这个表单[0,8],[1,2],[2,3],[3,11],[4,19],[5,13],[6,10]中。有没有内置的php函数可以做到这一点？

Answer 1

$out = array();
foreach($array as $k => $v) {array_push($out, array($k, $v)); }

Answer 2

$new_arr = array_map(null, array_keys($arr), $arr);

Answer 3

大致是这样的：

$array = array ( '0' => 8, '1' => 2, '2' => 10, '3' => 11, '4' => 19, '5' => 13, '6' => 10 );

$tempArray = array();
foreach( $array as $key => $value )
{
    $tempArray[] = '[' .$key .',' .$value .']';
}

$imploded = implode( ',' , $tempArray );

echo $imploded;

输出：

[0,8],[1,2],[2,10],[3,11],[4,19],[5,13],[6,10]
