How to do compression in rcon?

Question

PHP

<?php
backup_database_tables('Хост','База','Пароль','Имя базы', '*');
 
// Функция резервного копирования базы данных
function backup_database_tables($host,$user,$pass,$name,$tables)
{
 
    $link = mysql_connect($host,$user,$pass);
    mysql_select_db($name,$link);
 
    //Получаем все таблицы
    if($tables == '*')
    {
        $tables = array();
        $result = mysql_query('SHOW TABLES');
        while($row = mysql_fetch_row($result))
        {
            $tables[] = $row[0];
        }
    }
    else
    {
        $tables = is_array($tables) ? $tables : explode(',',$tables);
    }
 
    //Цикл по всем таблицам и формирование данных
    foreach($tables as $table)
    {
        $result = mysql_query('SELECT * FROM '.$table);
        $num_fields = mysql_num_fields($result);
 
        $return.= 'DROP TABLE '.$table.';';
        $row2 = mysql_fetch_row(mysql_query('SHOW CREATE TABLE '.$table));
        $return.= "\n\n".$row2[1].";\n\n";
 
        for ($i = 0; $i < $num_fields; $i++)
        {
            while($row = mysql_fetch_row($result))
            {
                $return.= 'INSERT INTO '.$table.' VALUES(';
                for($j=0; $j<$num_fields; $j++)
                {
                    $row[$j] = addslashes($row[$j]);
                    $row[$j] = ereg_replace("\n","\\n",$row[$j]);
                    if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
                    if ($j<($num_fields-1)) { $return.= ','; }
                }
                $return.= ");\n";
            }
        }
        $return.="\n\n\n";
    }
 

  $date = date('m-d-Y-H-i-s', time()); 
  $filename = $folder."db-backup-".$date; 

  $handle = fopen($filename.'.sql','w+');
    fwrite($handle,$return);
    fclose($handle);
}
?>

How can I do compression in .zip, otherwise the sql file takes 14mb without compression, and 1.4mb with compression. And the files are backed up every hour and 14 mb is a lot.

Answer 1

mysqldump -hserver -uuser -ppassword database | gzip > `date +'%Y-%m-%d-%H'`.sql.gz

And the horror that is written in the text of the question should be printed on a printer and burned.

Answer 2

I strongly advise you to read about mysqldump (there are all the functions that you typed in php) and why it is no longer fashionable to use mysql_
