how to upload a csv file to mysql database using php

Question

I have created a website which requires me to upload a csv file into the mysql database (Wamp server). Since I have never done this before a detailed answer with steps will be really helpful. I need the user to upload file using html input file option and then a php code to upload this file to mysql database. Iam using this code

<?php
$con=mysql_connect("localhost","","");
mysql_select_db("sg",$con);
define('CSV_PATH','C:/Users/mkutbudd/Desktop/');
$csv_file = CSV_PATH . "dum.csv";
if (($getfile = fopen($csv_file, "r")) !== FALSE) { 
        $data = fgetcsv($getfile, 1000, ",");
        while (($data = fgetcsv($getfile, 1000, ",")) !== FALSE) {
         $num = count($data); 
         for ($c=0; $c < $num; $c++) {
             $result = $data; 
             $str = implode(",", $result); 
             $slice = explode(",", $str);
             $col1 = $slice[0]; 
             $col2 = $slice[1];
             $col3 = $slice[2]; 
$query = "INSERT INTO dummy(dum1,dum2,dum3)
VALUES('".$col1."','".$col2."','".$col3."')";
$s=mysql_query($query, $con ); 
     }
   } 
  }
echo "File data successfully imported to database!!"; 
mysql_close($con); 
?>

• Your first step is to allow user to upload a file, and then you need to handle the errors if there are, validate the file, and if everything is correct, then move the uploaded file to its place: http://php.net/manual/en/features.file-upload.php

• Then you need to parse your file, with a php function for it: http://hu1.php.net/manual/en/function.fgetcsv.php

• After this, you need to create a connection to the database: http://hu1.php.net/manual/en/book.mysqli.php

• And then you need to insert your data into your table with a loop, like foreach on your array, what you created from fgetcsv: http://hu1.php.net/manual/en/control-structures.foreach.php

There are an alternative way, if you have right to run system or execute functions and you have right to run mysql command, then you can use the mysql load data command: http://dev.mysql.com/doc/refman/5.1/en/load-data.html

Done.
