Denne kode klarer det.
Du skal blot indsætte adgangsoplysningerne til din database i linjerne 4-7.
Husk også at angive de tabeller, du ønsker dumpet: Dette gør du i linjerne 184-186 og hvor du blot kan indsætte flere tabeller.
Så virker det.
Men du bør også være opmærksom på adgangen til php-filen, så uautoriserede ikke kan aktivere den.
Koden kommer her:
<?php
function ini(){//Opsætning af databaseparametre.
$config['db_serv'] = "localhost"; //Databaseserver (fx localhost)
$config['db_user'] = "root"; //Databasebruger (fx root)
$config['db_pass'] = ""; //Databasepassword (fx 123456)
$config['db_base'] = "flerkal"; //Databasenavn (fx menu)
return $config; //Returner valgte konfiguration
}
$config = ini();
mysql_connect($config[db_serv],$config[db_user],$config[db_pass]) or die (mysql_error());
mysql_select_db($config[db_base]) or die (mysql_error());
//ret herunder
$dbhost = $config[db_serv]; // Angiv din host til MySQL?
$dbuname = $config[db_user]; // Dit Brugernavn?
$dbpass = $config[db_pass]; // Dit Password?
$dbname = $config[db_base]; // Angiv Database navn
/*
Dette script generer en txt fil til download med et fuldstændigt dump af din database. Det er en modifikation af backup scriptet der følger med PHPnuke.
Hvordan bruger jeg det:
Ret oplysningerne nedenfor. Lav en fil og kald den hvad du vil. Når du aktiverer filen, vil scriptet tage backup af din database - nemt ik ;o).
