Export Database Table

DOWNLOAD               LIVE DEMO

This operation need some PHP code and header code make the operation successful from the browser, that's why we have to use the header code in this. and this code need some files those files are,
  1. db.php
  2. export.php
  3. index.php
as in the db.php file, make this.

database name --> 2my4edge
table name--> export_table
column names --> id,name,place

and as you, here i just declare what i have given in.

DB.PHP

<?php
$conn = mysql_connect('localhost', 'root', '') or die(mysql_error());
$db=mysql_select_db('2my4edge', $conn) or die(mysql_error());
?>

EXPORT.PHP

<?php
include('db.php');

//header to give the order to the browser
header('Content-Type: text/csv');
header('Content-Disposition: attachment;filename=exported-data.csv');

//select table to export the data
$select_table=mysql_query('select * from export_table');
$rows = mysql_fetch_assoc($select_table);

if ($rows)
{
getcsv(array_keys($rows));
}
while($rows)
{
getcsv($rows);
$rows = mysql_fetch_assoc($select_table);
}

// get total number of fields present in the database
function getcsv($no_of_field_names)
{
$separate = '';


// do the action for all field names as field name
foreach ($no_of_field_names as $field_name)
{
if (preg_match('/\\r|\\n|,|"/', $field_name))
{
$field_name = '' . str_replace('', $field_name) . '';
}
echo $separate . $field_name;

//sepearte with the comma
$separate = ',';
}

//make new row and line
echo "\r\n";
}
?>

INDEX.PHP

this file is just for do the download, just give the link anchor tag, usually you know to make just click export the data, for that just give the link on anchor link, that will export the data table.
<a href="export.php"> export the database table </a>

as given in the above line. just do it as i mentioned the above.

  12. Great tutorial! Would it be possible to mark the records as exported when the xml is generated and only export records that have not been exported on each run.

    Additionally, could the column names be defined in the xml differently than what is defined in the mysql table.
