PHP Codeigniter-Uninitialized string offset: - php

Question

I'm trying to upload excel file get the value and save it to database, the weird thing is when my excel file has 13 rows and up then the error Uninitialized Offset is occurred.
if (isset($dataRow)) {
foreach($dataRow as $key => $dataVal) :
foreach($dataVal as $key => $dataSume)
$fArray = $dataSume;
$y = count ($dataSume);
for($x=0; $x < 1; $x++ ){
if ( isset($fArray) ){
$this->varOrder->addCount($fArray[0],$fArray[1],$fArray[2],$fArray[3],$fArray[4],$fArray[5],$fArray[6],$fArray[7],$fArray[8],$flag2);
}
}
endforeach;
this is the value of $dataRow array.
array(12) { [0]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(123) [2]=> string(5) "apple" [3]=> float(45) [4]=> string(2) "pc" [5]=> string(5) "A1011" [6]=> float(1101) [7]=> float(42110) [8]=> string(3) "asd" } } [1]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(6) "grapes" [3]=> float(2) [4]=> string(3) "box" [5]=> string(5) "A1012" [6]=> float(1101) [7]=> float(42111) [8]=> string(3) "asd" } } [2]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(6) "grapes" [3]=> float(20) [4]=> string(3) "box" [5]=> string(5) "A1016" [6]=> float(1101) [7]=> float(42111) [8]=> string(3) "asd" } } [3]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(5) "chico" [3]=> float(7) [4]=> string(3) "box" [5]=> string(5) "A1012" [6]=> float(1101) [7]=> float(42111) [8]=> string(3) "ads" } } [4]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(125) [2]=> string(9) "pineapple" [3]=> float(8) [4]=> string(3) "box" [5]=> string(5) "A1013" [6]=> float(1102) [7]=> float(42112) [8]=> string(3) "ads" } } [5]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(123) [2]=> string(5) "apple" [3]=> float(45) [4]=> string(2) "pc" [5]=> string(5) "A1011" [6]=> float(1101) [7]=> float(42110) [8]=> string(3) "asd" } } [6]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(6) "grapes" [3]=> float(2) [4]=> string(3) "box" [5]=> string(5) "A1012" [6]=> float(1101) [7]=> float(42111) [8]=> string(3) "asd" } } [7]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(6) "grapes" [3]=> float(20) [4]=> string(3) "box" [5]=> string(5) "A1016" [6]=> float(1101) [7]=> float(42111) [8]=> string(3) "asd" } } [8]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(5) "chico" [3]=> float(7) [4]=> string(3) "box" [5]=> string(5) "A1012" [6]=> float(1101) [7]=> float(42111) [8]=> string(3) "ads" } } [9]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(125) [2]=> string(9) "pineapple" [3]=> float(8) [4]=> string(3) "box" [5]=> string(5) "A1013" [6]=> float(1102) [7]=> float(42112) [8]=> string(3) "ads" } } [10]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(123) [2]=> string(5) "apple" [3]=> float(45) [4]=> string(2) "pc" [5]=> string(5) "A1011" [6]=> float(1101) [7]=> float(42110) [8]=> string(3) "asd" } } [11]=> array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(6) "grapes" [3]=> float(2) [4]=> string(3) "box" [5]=> string(5) "A1012" [6]=> float(1101) [7]=> float(42111) [8]=> string(3) "asd" } } }
this is the only value that system get when the number of rows is 13.
array(1) { [0]=> array(9) { [0]=> string(8) "CC-00057" [1]=> float(124) [2]=> string(6) "grapes" [3]=> float(2) [4]=> string(3) "box" [5]=> string(5) "A1012" [6]=> float(1101) [7]=> float(42111) [8]=> string(4) "a1a1" } }
I tried to add if ( isset($fArray) ) before the for loop to catch the offset, but still didn't work.
is this problem is on my foreach or for loop?
thanks in advance!
