Import Excel file(date) into mysql database in php

I try to import excel file which contains data date(yyyy-mm-dd) into mysql database in php. But it not insert the data in mysql.

Code

$fp = fopen("data.csv",'w');
fwrite($fp,ob_get_contents());
fclose($fp);
//echo"----";   
ob_end_clean();
//connect to the database 
$connect = mysql_connect("localhost","root",""); 
mysql_select_db("DBA",$connect); //select the table 
//$file = $_FILES['data.csv']['tmp_name']; 
$handle = fopen('data.csv',"r"); 
//loop through the csv file and insert into database 
GLOBAL $data;
do { 

 if($data[0]!="")
 {
mysql_query("INSERT INTO productsegmentmaster VALUES ( '$data[0]', '$data[1]','$data[2]')"); 

  }
} while ($data = fgetcsv($handle,1000,"*","'")); 
}
fclose($handle);
echo"<script>alert('File $path Imported Successfully')</script>";
unlink('data.csv');
unlink($path);
