prblem with geting back up from db

[hno]

HI

I have written this script to geting back up from data base and save it in a file :

 

ob_start();

$db=mysqli_connect("localhost","root","","php");

$tableName  = 'user';

$backupFile = 'b/user.sql';

$query= "SELECT * INTO OUTFILE '$backupFile' FROM $tableName";

$result = mysql_query($query);

echo mysqli_connect_error() ;

if ($result) echo "success";

 

it is not working

 

what is the problem ?

 

thanks

Well the main problem I can see is you've not provided us with enough details to help. In what way does it not work, what appears on screen? Does it say success but the file isn't there? Is the file there but empty? Does the screen not say success but has an error message? If so what? Is the screen blank and there's no file?

 

Help us, help you.

db backups are a lot easier from the command line ( using mysqldump )

 

mysqldump -h host -u user -p passwd db > backup.sql
