<?php

ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

$database = 'db';
$user = 'user';
$pass = 'pass';
$host = 'localhost';

Hi,

Excellent script. Thanks a lot ..
By the way, if you i want to just dump the tables structures of the DB. How to do that? thanks in advance.

https://dev.mysql.com/doc/refman/8.0/en/show-create-table.html
For structure only.

Error occur while running above script please help me to solve this.

array (size=2)
0 => string ''mysqldump' is not recognized as an internal or external command,' (length=65)
1 => string 'operable program or batch file.' (length=31)

You have to add MySQL_Installation_Path/bin to PATH. For example if you are using MariaDB and your installation path is:

• C:/MariaDB

Well you have to add C:/MariaDB/bin to system path.

thanks a lot

Just use mysqldump-php within your php code. Check out the examples or the wiki, but it is as easy as:

error_reporting(E_ALL);

require_once __DIR__ . '/vendor/autoload.php';
include_once(dirname(__FILE__) . '/vendor/mysqldump-php/src/Ifsnop/main.inc.php');

use Ifsnop\Mysqldump as IMysqldump;

try {
    $dump = new IMysqldump\Mysqldump('mysql:host=localhost;dbname=testdb', 'username', 'password');
    $dump->start('storage/work/dump.sql');
} catch (\Exception $e) {
    echo 'mysqldump-php error: ' . $e->getMessage();
}

OK MERCI

}

Work fine!

If you're in windows like me and don't want create a ENVIRONMENT VARIABLE, you can use the mysql dir before the dump command

<?php

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

define('DS', DIRECTORY_SEPARATOR);

$database = 'etsy';
$user = 'root';
$pass = '';
$host = 'localhost';
$dir = dirname(__FILE__) . DS . 'dump.sql';

$mysqlDir = 'D:'.DS.'wamp64'.DS.'bin'.DS.'mysql'.DS.'mysql8.0.18'.DS.'bin';    // Paste your mysql directory here and be happy
$mysqldump = $mysqlDir.DS.'mysqldump';

echo "<h3>Backing up database to `<code>{$dir}</code>`</h3>";
exec("{$mysqldump} --user={$user} --password={$pass} --host={$host} {$database} --result-file={$dir} 2>&1", $output);

var_dump($output);

The script works well locally, now how can I use it externally?

Thanks a lot for this script.

I improved it with a bit of bash and a desktop launcher, it's written in French but this may interest someone:

Hi guys,

first of all let me thank you for the amazing simple script.. it works great, but i needed to add some features to fit my project, such as save file from input form in php, where we select de name of the backup and post it to the execut backup script, and then download file in webrowser directly. attached below is a working example of the code.

And yeahhh keep up the good work lads.

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

include_once("conect-db.php");

$name_backup = $_REQUEST['name_backup'];

$command='mysqldump --opt -h' .$databaseHost .' -u' .$databaseUsername .' -p' .$databasePassword .' ' .$databaseName .' > ' .$name_backup;
exec($command,$output,$worked);

$file_name = basename($name_backup);
//save the file by using base name
$fn = file_put_contents($file_name,file_get_contents($name_backup));
header("Expires: 0");
header("Last-Modified: ".gmdate("D, d M Y H:i:s")." GMT");
header("Cache-Control: no-store, no-cache, must-revalidate");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
header("Content-type: application/file");
header('Content-length: '.filesize($file_name));
header('Content-disposition: attachment; filename="'.basename($file_name).'"');
readfile($file_name);

switch($worked){
case 0:
echo 'The database ' .$databaseName .' was successfully stored in the following path '.getcwd().'./' .$name_backup .'';
break;
case 1:
echo 'An error occurred when exporting ' .$databaseName .' zu '.getcwd().'/' .$mysqlExportPath .'';
break;
case 2:
echo 'An export error has occurred, please check the following information:

MySQL Database Name:	' .$databaseName .'
MySQL User Name:	' .$databaseUsername .'
MySQL Password:	NOTSHOWN
MySQL Host Name:	' .$databaseHost .'

';
break;
}
?>
