Undefined offset using fopen csv - php

Question

Hey guys im having a problem with a script im working on.
Im getting two errors and i dont understand why.
I do know that the csv file is csv comma delimited type.
Errors
Notice: Undefined variable: data in /home1/public_html/tickets/inv.php on line 17
Notice: Undefined offset: 7 in /home1/public_html/tickets/inv.php on line 20
Here is a link to my csv file: http://goo.gl/tcNNm1
//connect to the database
$connect = mysql_connect("*****","*********","*******");
mysql_select_db("don=_scanner",$connect); //select the table
//
$file = "rfl2.csv";
$handle = fopen($file,"r");
//loop through the csv file and insert into database
do {
if ($data[0]) {
mysql_query("INSERT INTO inv (stk, vin) VALUES
(
'".addslashes($data[7])."',
'".addslashes($data[8])."'
)
");
}
} while ($data = fgetcsv($handle,1000,",","'"));
I had this script working with a file i upload through a forum but im trying to make it load that one file when i request the page.

Answer 1

You're using the wrong kind of loop. $data will not be defined until after the FIRST iteration of the loop, because the $data = fgetcsv() will not be executed until the do/while's innards have been run once already.
You want
while($data = fgetcsv(...)) {
... database insert ...
}
instead
Plus, you are vulnerable to sql injection attacks. addslashes is utterly useless for protection against this. At least use the proper mysql_real_escape_string().
while(...) {...} - execute loop contents only if the condition is true
do {...} while(...) - execute loop contents at least once, terminate if condition is false

Answer 2

As the property of Do-While , it runs at least once. So at first iteration, $data variable is undefined. hence error!. Possible solution is do something like:
if(isset($data)) instead of if($data). or better go for while loop or for loop.

Answer 3

do this:
while(!feof($handle)){
$values = fgetcsv( $handle);
if(isset($values[0])){
add sql here..
}
}
