how to take mysql backup using php

Many time we are have to take mysql server database back up since we need it and it can be done by using cpanel for our server but what if when we don't have a cpanel or we don't want to give our client but our client wants to take regular backup of database then we can make a simple script file to take backup

like below 

< ?php
$datestamp = date("Y-m-d");      // Current date to append to filename of backup file in format of YYYY-MM-DD

/* CONFIGURE THE FOLLOWING SEVEN VARIABLES TO MATCH YOUR SETUP */
$dbuser = "";            // Database username
$dbpwd = "";            // Database password
$dbname = "";            // Database name. Use --all-databases if you have more than one
$filename= "backup-$datestamp.sql.gz";   // The name (and optionally path) of the dump file
$to = "you@remotesite.com";      // Email address to send dump file to
$from = "you@yourhost.com";      // Email address message will show as coming from.
$subject = "MySQL backup file";      // Subject of email

$command = "mysqldump -u $dbuser --password=$dbpwd $dbname | gzip > $filename";
$result = passthru($command);

$attachmentname = array_pop(explode("/", $filename));   // If a path was included, strip it out for the attachment name

$message = "Compressed database backup file $attachmentname attached.";
$mime_boundary = "< <<:" . md5(time());
$data = chunk_split(base64_encode(implode("", file($filename))));

$headers = "From: $from\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-type: multipart/mixed;\r\n";
$headers .= " boundary=\"".$mime_boundary."\"\r\n";

$content = "This is a multi-part message in MIME format.\r\n\r\n";
$content.= "--".$mime_boundary."\r\n";
$content.= "Content-Type: text/plain; charset=\"iso-8859-1\"\r\n";
$content.= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$content.= $message."\r\n";
$content.= "--".$mime_boundary."\r\n";
$content.= "Content-Disposition: attachment;\r\n";
$content.= "Content-Type: Application/Octet-Stream; name=\"$attachmentname\"\r\n";
$content.= "Content-Transfer-Encoding: base64\r\n\r\n";
$content.= $data."\r\n";
$content.= "--" . $mime_boundary . "\r\n";

mail($to, $subject, $content, $headers);

unlink($filename);   //delete the backup file from the server
?>

Enjoy PHP !!
