This is the array which i get from post

(
[data] => Array

[itemNo] => Array

[0] => rtgrg
[1] => 4t4t
[2] => ththt
[3] => thth

[itemName] => Array

[1] => 4t5t5
[2] => hthtyh
[3] => gnghnn
)
[itemDiscription] => Array

[0] => 5tr5t
[1] => t45t4
[2] => tyhthtyh
[3] => gnghnh
)
[price] => Array
(
[0] => 2
[1] => 10
[2] => 9
[3] => 12
)
[itemQuantity] => Array
(
[0] => 2
[1] => 12
[2] => 9
[3] => 9
)
[itemDiscount] => Array
(
[0] => 11
[1] => 0.14
[2] => 0.13
[3] => 0.1
)
[itemTotal] => Array
(
[0] => 333333
[1] => 34535
[2] => 55555555555555
[3] => 666666666
)
[itemStartDate] => Array
(
[0] =>
[1] =>
[2] =>
[3] => 2016-06-17
)
[itemEndDate] => Array
(
[0] =>
[1] =>
[2] =>
[3] =>
)
[itemCustomcol] => Array
(
[0] => 4t4t4
[1] => t5trgr
[2] => htht
[3] => gngh
)
[itemCustomcol2] => Array
(
[0] => t4t4t
[1] => rtgtr
[2] => thth
[3] => gng
)
[itemttax2] => Array
(
[0] => tax1
)
[itemttax3] => Array
(
[0] => tax1
)
[itemttax4] => Array
(
[0] => tax1
)
[itemtCsTax] => Array
(
[0] => gngn
)
[itemtCsTaxPer] => Array
(
[0] => 0.1
)
[itemtDiscount] => Array
(
[0] => 0.18
)
[itemtInvReceived] => Array
(
[0] => gngn
)
[itemtInvToReturn] => Array
(
[0] => gngng
)
[itemInvDue] => Array
(
[0] => nghnghng
)
[itemInvComment] => Array
(
[0] => hngnhg
)
)
)
There is a separate table for dynamic input like itemName, itemDiscription to itemCustomcol2 and another table for itemttax2 to itemInvComment .
I tried foreach loop for multiple element array but this doent work for me as it returns a string. one of them is shown below
$capture_field_vals ="";
foreach($_POST["data"]["Invoice"]["itemNo"] as $key => $text_field){
$capture_field_vals .= $text_field .", ";
}
echo $capture_field_vals;
What i want is collect all element[0] and then insert it in a row mysql and then another element another row and so on.

Is there any reason you can't use the following format?
Array
(
[data] => Array
(
[Invoice] => Array
(
[0] => Array
(
[itemNo] => number
[itemName] => name
[itemDescription] => desc
[price] => 0.00
),
[1] => Array
(
[itemNo] => number
[itemName] => name
[itemDescription] => desc
[price] => 0.00
),...
with this method you can loop through retrieving all details of each item in the invoice?
If I have misunderstood your problem, I apologise
