Dumping a MySQL datavase with php

I'm looking for a way to move a MySQL database from one web derver to another.

Through a Google search I found MySQL Dump Class. It looks like it might work, but the example (as follows) is TOTALLY confusing. I want to save the dumped database to a file that I can ftp to my local machine & upload to a new host.

This "example" script seems like it "prints" the dump? Why on earth do that? Also, there is no reference to "mydb". What is that?

<?php

mysql_connect("localhost", "root", "");

require("class_mysqldump.php");
$dump = new MySQLDump();

print $dump->dumpDatabase("mydb");

?>

Can someone help me understand this example script or point me to another way? I want to dump the MySQL database to a file. I ONLY have ftp access & the current web host is uncooperative. I DO NO have general command line access at the server so I don't think I can use MySQL Dump.

Thanks

well, simply write to a file instead of printing to the screen:
http://php.net/fwrite

here a complete script:

mysql_connect("localhost", "root", "");
mysql_select_db("database_name");

require("class_mysqldump.php");
$dump = new MySQLDump();

$data = $dump->dumpDatabase("mydb");

$filename = 'test.txt';

// Let's make sure the file exists and is writable first.
if (is_writable($filename)) {

   // In our example we're opening $filename in append mode.
   // The file pointer is at the bottom of the file hence
   // that's where $somecontent will go when we fwrite() it.
   if (!$handle = fopen($filename, 'a')) {
         echo "Cannot open file ($filename)";
         exit;
   }

   // Write $somecontent to our opened file.
   if (fwrite($handle, $data) === FALSE) {
       echo "Cannot write to file ($filename)";
       exit;
   }
 
   echo "Success, wrote database dump to file ($filename)";
 
   fclose($handle);

} else {
   echo "The file $filename is not writable";
}
