Simple PHP script to dump a MySql database

mysqldump.php

<?php

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

$database = 'db';
$user = 'user';
$pass = 'pass';
$host = 'localhost';
$dir = dirname(__FILE__) . '/dump.sql';

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);

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;
}
?>
