In this tutorial i will show you how to export your data from Mysql into a CSV file.

Fist off we start by creating the connection to the Mysql database:

  • $host: this is the location for the Mysql server it can be a hostname or an ip adress. it is usualy localhost.
  • $db: this is the Mysql user account used to access the database.
  • $user: this is the password for the Mysql user account
  • $pass: this is the name of the Mysql database used.

Now we include the export function.

We will need to include the function ‘exportMysqlToCsv‘ in the file ‘exportcsv.inc.php‘

Now we declare what table should be exported from Mysql into the CSV file:

  • $table: The name of the table that should be exported from Mysql to csv.

Now we start the export to csv from mysql by calling the function ‘exportMysqlToCsv‘:

This function will export all data in the Mysql table. It will place the fieldnames on the first row of the CSV file.
The function will export all Mysql data to a file called ‘export.csv’ by default.
You can change this by adding an extra parameter to the exportMysqlToCsv: exportMysqlToCsv($tablename,$filename).
When the export finishes all your data will be inserted into the csv file and the file will be presented as a download.

mysql_select_db($db);
 
require 'exportcsv.inc.php';
 
$table=""; // this is the tablename that you want to export to csv from mysql.
 
exportMysqlToCsv($table);
 
?>

The actual Mysql Export to csv function:

Feel free to alter this file to your needs:

To change the default filename of the exported data change the $filename variable to your likings.

In this tutorial i will show you how to export your posts from cutenews into a mysql table.

Fist off we start by creating the connection to the database:

  • $host: this is the location for the Mysql server it can be a hostname or an ip adress. it is usualy localhost.
  • $db: this is the Mysql user account used to access the database.
  • $user: this is the password for the Mysql user account
  • $pass: this is the name of the Mysql database used.

Now we include the export function.

We will need to include the function ‘cuteExport’ in the file ‘cutenewsexport.php’

Now we declare what data files should be exported from cutenews:

  • $newsfile: Cutenews uses ‘news.txt’ for it’s data. Specify the FULL path to this file.
  • $categoryfile: Cutenews uses ‘category.db.php’ for it’s categories. Specify the FULL path to this file.

Now we start the export to mysql by calling the function ‘cuteExport’:

This function will export all data in the ‘news.txt’ file and ‘category.db.php’ and import it in a Mysql table.
The function will export all data to a table called ‘cutenews_export_year_month_day_hour_min_sec’ by default.
You can change this in the cutenewsexport file where it says ‘$table = “cutenews_export_” . date(“Y_m_d_h_i_s”);’.
When the function finishes all your data will be inserted into a mysql table.

To change the default table name change the $table variable to your likings.

You can also export categories to a mysql table and use the ID as a reference in the export table.

$host = 'localhost'; // MYSQL database host adress
$db = ''; // MYSQL database name
$user = ''; // Mysql Datbase user
$pass = ''; // Mysql Datbase password
 
$link = mysql_connect($host, $user, $pass);
mysql_select_db($db);
 
$table = 'cutenews_export_2007_12_13_10_13_15';
$categoryid = (int) htmlentities($_GET['cat']); // You should make this more secure...
 
$sql = "select * from $table where categoryid = '$categoryid' order by date ";
 
$result = mysql_query($sql);
 
// displaying the actual page results:
 
while ($row = mysql_fetch_array($result))
{
 
    echo "
<div id ='news_$row[id]'>
<h1>$row[title] @ ".date("l jS M Y @ g:ia", $row['date'])."</h1>
<div>$row[short]</div>
<div>$row[full]</div>
</div>
";
}
?>

Now you can easily display news per category using a URL like: news.php?category=some_category_id
