Hi,

 

I have this script for backing up a database that when it is run the option comes up to save the file. Can anyone show me how I would change this script so that the script automatically saves the file in a specified folder?

 

<?php 
set_time_limit(0); 
$mysqldump_version="1.02"; 
  
  
$output_messages=array(); 
  
    $mysql_host= 'localhost'; 
    $mysql_database= '**';

    $mysql_password= '**';  
  
            _mysql_test($mysql_host,$mysql_database, $mysql_username, $mysql_password); 
  
  
  
            //ob_start("ob_gzhandler"); 
            header('Content-type: text/plain'); 
            header('Content-Disposition: attachment; filename="'.$mysql_host."_".$mysql_database."_".date('YmdHis').'.sql"'); 
            echo "/*mysqldump.php version $mysqldump_version */\n"; 
            _mysqldump($mysql_database); 
  
  
function _mysqldump($mysql_database) 
{ 
    $sql="show tables;"; 
    $result= mysql_query($sql); 
    if( $result) 
    { 
        while( $row= mysql_fetch_row($result)) 
        { 
            _mysqldump_table_structure($row[0]); 
  
            _mysqldump_table_data($row[0]); 
  
        } 
    } 
    else 
    { 
        echo "/* no tables in $mysql_database */\n"; 
    } 
    mysql_free_result($result);

I don't really understand that.

 

I know I have to change this part of my code

header('Content-type: text/plain'); 
            header('Content-Disposition: attachment; filename="'.$mysql_host."_".$mysql_database."_".date('YmdHis').'.sql"'); 
            echo "/*mysqldump.php version $mysqldump_version */\n"; 
            _mysqldump($mysql_database); 
  

 

Can anyone show me how?
