如果你在这个循环迭代中发现任何其他错误，请告诉我。
我有一个标题为$form_data的数组，如下所示:
Array

[op] => preview
[id] =>
[form_submitted] => yes
[company_id] => 46
[1] => Array

[pack] => 10
[quantity] => 20

[rebate_expiry_date] => 2014-05-05
[applicable_states] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
[rebate_total_count] => 5000
[products] => Array

$form_data阵列和$error_msgs阵列。其他对象是在类的构造函数中创建的。所以，请忽略这些东西，并考虑我在foreach循环中得到的错误。
function ValidateRebateByProductFormData($form_data, $errors_msgs) {

在上面的代码中，我添加了一个注释来指示行号。我得到警告的地方。
$products似乎没有定义。你的意思是:
foreach( $value as $k => $v) {
再看一遍，它应该是:
foreach($element as $key => $value) {
/*check for each key of inner array [1], [2], [3],.. whether it's an array or not*/
if(is_array($value)) {
foreach($value as $key1=>$value1){
if($key1 == 'products') {
foreach($value['products'] as $k => $v) {
在循环到达的地方:
[1] => Array
(
[pack] => 10
您正在检查is_array()，但您需要进入嵌套的级别，以获得键 products。
你把事情弄得更复杂了。
foreach($form_data as $key => $value) {
if(is_array($value)) {
foreach($value['products'] as $productkey => $productValue) {
echo $productKey; // This is the key.
echo $productValue; // This is the actual product ID.
}
}
}
