I know its a bit late but hope someone else will find this.

//php file - html code:
    require_once 'connect.php'; //holds database variables with connect details
    require_once 'Admin_DatabaseFiles_Backup.php'; //Include the admin logout script

<form action="" method="post" class="form form">
    <!--<input type="hidden" name="backup" value="1" />-->
    <div class="float_left w200">
        <p>
            <label class="title">Backup database</label>
            <span class="left">
              <input type="checkbox" name="db" value="1" checked="checked"/>
            </span>
        </p>
        <p>
            <label class="title">Backup files</label>
            <span class="left">
                <input type="checkbox" name="files" value="1" checked="checked" />
            </span>
        </p>
    </div>
    <p class="float_left">
        <input type="submit" name="submit" value="Backup" class="button" />
    </p>
</form>

//php file Admin_DatabaseFiles_Backup.php:
<?php


if ($_POST['submit']=="Backup"){

    if ($_POST['db'] == "1"){

        $directory = "DatabaseFileBackups/";
        $dateAndTime = "".date('d-m-Y-H-i-s');
        $fileName = "".$dbname.$dateAndTime.".sql";
        $backupFile = "mysqldump --user=$dbuser --password='$dbpass' --host=$dbhost $dbname > ".$directory.$fileName;

        exec($backupFile,$output);

        if($output == ''){ 
            echo = '<br />Failed To Backup Database!';
        }else{
            echo = '<br />Database Backup Was Successful!';
        }
    }

    if ($_POST['files'] == "1"){

            echo 'Seleceted files';

    }
}


?>

A very simple solution would be something like (first example): http://www.php-mysql-tutorial.com/wikis/mysql-tutorials/using-php-to-backup-mysql-databases.aspx

Naturally this will only make a Data dump of the table.

What you could do is use this code:

http://snipplr.com/view/173/mysql-dump/

What this code does is actually gets a description of the table (i.e its structure), creates all the tables and pushes data. pretty much like any other tool does.

Then its just a matter of saving it from string to a file (file_put_contents() for instance or something similar, depending on your preference and need)

Use phpmyadmin

Edit:

You can use shell_exec to execute this command

mysqldump -u username -p password database > file

This will generate a dump file,and then redirect user to this generated file.

If you have phpMyAdmin you can do it at the Export menu.

If you look for a command-line tool take a look at mysqldump.

mysqldump -u username -p password database > file

Alternatively, phpMyAdmin can do this too with the Export tool.

Do you have phpmyadmin? If so you can export it from there by clicking "Export" at the top (on the selected table/db).
