php – 如何从多维数组中仅内插()一列?
作者:互联网
我有以下格式的数组:
Array
(
[sales] => Array
(
[0] => Array
(
[0] => 1
[1] => 6
)
[1] => Array
(
[0] => 2
[1] => 8
)
[2] => Array
(
[0] => 3
[1] => 25
)
[3] => Array
(
[0] => 4
[1] => 34
)
)
)
使用:
foreach ($data['sales'] as $k => $row) {
$list = implode(",",$row);
}
我得到以下输出:
1,62,83,254,34
但我只需要每个subArray的第二个值.预期结果必须是:
6,8,25,34
如何删除第一组值?
解决方法:
我喜欢array_column()但是如果你没有PHP> = 5.5.0:
$list = implode(',', array_map(function($v) { return $v[1]; }, $data['sales']));
或者与foreach:
foreach ($data['sales'] as $row) {
$list[] = $row[1];
}
$list = implode(',', $list);
