PHP - Array inside the loop returns empty - php

Question

I am trying to add data to 2 different MySql tables through a CSV upload. I have been able to retrieve the information and upload part of the information on one table, but I am having issues sending data to the second table. I have come up with the following code:
$i = 0;
//Loop through the csv file
do {
if ($data[0]) {
//Store request information
//Info for Request Table
$requester_email = $data[0];
$requester_name = $data[1];
$client_name = $data[2];
$client_country = $data[3];
$opportunity_number = $data[4];
$machine_quantity = $data[5];
$severity = $data[6];
//Store machine values
//Info for Serial Numbers Table
$serialType = array();
$serialModel = array();
$serialType[$i] = $data[7];
$serialModel[$i] = $data[8];
}
$i++;
} while ($data = fgetcsv($handle,1000,",","'"));
I am having an issue with the array. I have only been able to store the serialType and serialModel from the last line in the csv file. For example, if the csv file has 3 lines of data:
(
[0] => Empty
[1] => Empty
[2] => Last Value ok
)
How come I am unable to store the other two values?

Just move
$serialType = array();
$serialModel = array();
before do in your script. While it is still inside the do loop it is just a initialize variable in do - while scope each iteration and clean it up.
$i = 0;
$serialType = array();
$serialModel = array();
while ($data = fgetcsv($handle,1000,",","'")) {
...
$serialType[$i] = $data[7];
$serialModel[$i] = $data[8];
$i++;
};
