在某些数组值中查找点并用逗号替换

Question

我有这样的数组

Array
(
    [0] => Array
        (
            [0] => Price
            [1] => 308.5
            [2] => 2009

        )

    [1] => Array
        (
            [0] => Price
            [1] => 308.5
            [2] => 2009

        )

)

我需要将"."替换为"," in key [0][1], [1][1], [2][1]等

Answer 1

这样可行，注意您必须使用sub_array作为参考

foreach ($arr as &$sub_arr) {
  foreach ($sub_arr as &$val) {
    $val = str_replace('.', ',', $val);
  }
}

Answer 2

试

foreach($arr as $v) {
  foreach($v as $v1) {
    $newarr[] = str_replace('.', ',', $v1);
  }
}
print_r($newarr);
