与数组相关的问题

Question

我有两个阵列.我想连接到以下格式.格式如下所示.

    Getting form values using post method
    /************ Getting Form names like Weight,arms Age etc **********************/
      foreach ($_POST["form_field_names"] as $key => $values) {
    $form_field_name = $values;
}

/************ Getting Form Values like 45,90,2 **********************/
foreach ($_POST["form_field_values"] as $key => $values) {
    $form_field_values[] = $values;
}

Array
(
   [0] => Age
   [1] => Weight
   [2] => Arms
)
Array
(
  [0] => 45
  [1] => 90
  [2] => 2
)

想要连接到以下格式

$output = $Age.","."45".",".$Weight.","."90".",".$Arms.","."2".",";

可能吗？谢谢

我建议您首先将两个数组合并为一个关联数组:

$assoc = array_combine($keys_array1, $num_array2);

然后,只需循环生成输出字符串:

$str = "";
foreach ($assoc as $key=>$num) {
    $str .= "$key,$num,";
}

如果尾随,是一个问题(你没有说),那么我会采取一种$str = rtrim($str, ",")解决方法.
