Question

I m posting an array of ids and want to loop over those values. I m trying the following to populate an array with key/value pairs but it looks like the array is coming out empty.

$arr = array();
foreach($_POST[ ids ] as $id)
{
   $arr[$id] = GetStuff($id);
}

<><>UPDATE: 象阵列一样的眼光是有人用的罚款。 I m试图通过照读echo json_encode(arr)归还阵列内容,但答复是空白。

这里是var($_POST);

  array(1) {
  ["ids"]=>
  array(18) {
    [0]=>
    string(6) "156795"
    [1]=>
    string(6) "156800"
    [2]=>
    string(4) "4292"
    [3]=>
    string(6) "796053"
    [4]=>
    string(6) "660520"
    [5]=>
    string(4) "4293"
    [6]=>
    string(4) "4287"
    [7]=>
    string(6) "488339"
    [8]=>
    string(6) "837701"
    [9]=>
    string(7) "1152093"
    [10]=>
    string(7) "1186434"
    [11]=>
    string(7) "1324432"
    [12]=>
    string(6) "796051"
    [13]=>
    string(6) "144860"
    [14]=>
    string(5) "15065"
    [15]=>
    string(7) "1324434"
    [16]=>
    string(5) "13066"
    [17]=>
    string(4) "6969"
  }
}

Answer 1

foreach($_POST[ ids ] AS $i=>$id) {
    //do stuff
}

Don tabe about quotes.

Answer 2

$arr = array();
foreach($_POST[ ids ] as $id)
{
   $arr[$id] = GetStuff($id);
}

Answer 3

这一工作应当:

foreach($_POST[ ids ] as $id)
{
   $arr[$id] = $_POST[ ids ][$id];
}

如果你只是想要一个与所张贴的婴儿相同的阵列:

$arr = $_POST[ ids ];

除非我误解这个问题。
