1) Split the csv file line-by-line using explode()
2) Then insert into your mysql DB normally.

Before you can 'split' the cvs data, you need the following:[php]
// after uploading using a html form
$tmpName = $_FILES['userfile']['tmp_name'];
$fp = fopen($tmpName, 'r');
$fr=fread($fp, filesize($tmpName));
$line = explode("\n", $fr);
// etc etc ...
[/php]

<?

$contents = file ('./email_entries.csv');
for($i=0; $i<sizeof($contents); $i++)
{
$line = trim($contents[$i],'",');
$arr = explode(',', $line);
// $sql = "insert into employees values ('".implode("','", $arr)."')";
$sql = mysql_query("insert into employees(first_name,last_name,email_id) values ('".$arr[0]."','".$arr[1]."','".$arr[2]."')");
}
}

Hi,

Just run this code to enter your csv file into mysql. Also enter the database details in a file named config.inc.php.
-----------------


  1. <? include "../include/config.inc.php";
  2.  
  3.  
  4. function normalise($string) {
