无需访问服务器或phpmyadmin即可轻松导出SQL表

您可以为此使用SQL:

$file = 'backups/mytable.sql';
$result = mysql_query("SELECT * INTO OUTFILE '$file' FROM `##table##`");

然后将浏览器或FTP客户机指向目录/文件(backups/mytable.sql)。这也是一种进行增量备份的好方法,例如,给文件名一个时间戳。

要从该文件将其恢复到数据库中,可以使用:

$file = 'backups/mytable.sql';
$result = mysql_query("LOAD DATA INFILE '$file' INTO TABLE `##table##`");

另一个选项是使用php在服务器上调用系统命令并运行'mysqldump':

$file = 'backups/mytable.sql';
system("mysqldump --opt -h ##databaseserver## -u ##username## -p ##password## ##database | gzip > ".$file);

我通过导出到csv,然后用任何可用的实用程序导入。我非常喜欢使用php://output流。

$result = $db_con->query('SELECT * FROM `some_table`');
$fp = fopen('php://output', 'w');
if ($fp && $result) {
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename="export.csv"');
    while ($row = $result->fetch_array(MYSQLI_NUM)) {
        fputcsv($fp, array_values($row));
    }
    die;
}

你也应该考虑 phpMinAdmin 这只是一个文件,所以很容易上传和设置。

工作方案 (最新版本: Export.php + Import.php )

EXPORT_TABLES("localhost","user","pass","db_name");

代码:

//https://github.com/tazotodua/useful-php-scripts
function EXPORT_TABLES($host,$user,$pass,$name,  $tables=false, $backup_name=false ){
    $mysqli = new mysqli($host,$user,$pass,$name); $mysqli->select_db($name); $mysqli->query("SET NAMES 'utf8'");
    $queryTables = $mysqli->query('SHOW TABLES'); while($row = $queryTables->fetch_row()) { $target_tables[] = $row[0]; }   if($tables !== false) { $target_tables = array_intersect( $target_tables, $tables); }
    foreach($target_tables as $table){
        $result = $mysqli->query('SELECT * FROM '.$table);  $fields_amount=$result->field_count;  $rows_num=$mysqli->affected_rows;     $res = $mysqli->query('SHOW CREATE TABLE '.$table); $TableMLine=$res->fetch_row();
        $content = (!isset($content) ?  '' : $content) . "\n\n".$TableMLine[1].";\n\n";
        for ($i = 0, $st_counter = 0; $i < $fields_amount;   $i++, $st_counter=0) {
            while($row = $result->fetch_row())  { //when started (and every after 100 command cycle):
                if ($st_counter%100 == 0 || $st_counter == 0 )  {$content .= "\nINSERT INTO ".$table." VALUES";}
                    $content .= "\n(";
                    for($j=0; $j<$fields_amount; $j++)  { $row[$j] = str_replace("\n","\\n", addslashes($row[$j]) ); if (isset($row[$j])){$content .= '"'.$row[$j].'"' ; }else {$content .= '""';}     if ($j<($fields_amount-1)){$content.= ',';}      }
                    $content .=")";
                //every after 100 command cycle [or at last line] ....p.s. but should be inserted 1 cycle eariler
                if ( (($st_counter+1)%100==0 && $st_counter!=0) || $st_counter+1==$rows_num) {$content .= ";";} else {$content .= ",";} $st_counter=$st_counter+1;
            }
        } $content .="\n\n\n";
    }
    $backup_name = $backup_name ? $backup_name : $name."___(".date('H-i-s')."_".date('d-m-Y').")__rand".rand(1,11111111).".sql";
    header('Content-Type: application/octet-stream');   header("Content-Transfer-Encoding: Binary"); header("Content-disposition: attachment; filename=\"".$backup_name."\"");  echo $content; exit;
}

如果你有ftp/sftp访问权,你可以自己上传phpmyadmin。

我使用这个小软件包从我只有ftp访问权的服务器上进行自动mysql备份:
http://www.taw24.de/download/pafiledb.php?PHPSESSID=b48001ea004aacd86f5643a72feb2829&action=viewfile&fid=43&id=1
该网站是德语的,但下载也有一些英语文档。

一个快速的谷歌也会出现这种情况,但我自己没有使用它:
http://snipplr.com/view/173/mysql-dump/

你可以考虑看看: http://www.webyog.com 这是一个很好的GUI管理工具,他们有一个非常好的HTTP隧道功能(我不确定这是否只在企业中,它需要花费一些钱)。

基本上,您可以将它们提供的脚本上传到您的Webspace(PHP脚本)中,并将sqlyog manager指向它,然后您就可以访问数据库了。它使用此脚本在主客户机和服务器之间进行请求/查询的隧道/代理。

我知道至少有一个人用这种方法取得了很好的效果。

这里是一个 PHP 我编写的脚本将备份数据库中的所有表。是基于这个 http://davidwalsh.name/backup-mysql-database-php 还有一些改进。首先,它将正确设置 foreign key restrictions .

在我的设置中,脚本将在一周中的某一天运行,比如说星期一。如果它没有在星期一运行,它仍然会在星期二运行(例如),创建 .sql 把上个星期一的日期归档,当时它应该运行。它将抹去 SQL 文件来自4周前,因此它始终保留最后4个备份。代码如下:

<?php

backup_tables();

// backup all tables in db
function backup_tables()
{
    $day_of_backup = 'Monday'; //possible values: `Monday` `Tuesday` `Wednesday` `Thursday` `Friday` `Saturday` `Sunday`
    $backup_path = 'databases/'; //make sure it ends with "/"
    $db_host = 'localhost';
    $db_user = 'root';
    $db_pass = '';
    $db_name = 'movies_database_1';

    //set the correct date for filename
    if (date('l') == $day_of_backup) {
        $date = date("Y-m-d");
    } else {
        //set $date to the date when last backup had to occur
        $datetime1 = date_create($day_of_backup);
        $date = date("Y-m-d", strtotime($day_of_backup.' -7 days'));
    }

    if (!file_exists($backup_path.$date.'-backup'.'.sql')) {

        $link = mysqli_connect($db_host,$db_user,$db_pass);
        mysqli_set_charset($link,'utf8');
        mysqli_select_db($link,$db_name);

        //get all of the tables
        $tables = array();

            $num_fields = mysqli_num_fields($result);
            $num_rows = mysqli_num_rows($result);
            $i_row = 0;

            //$return.= 'DROP TABLE '.$table.';'; 
            $row2 = mysqli_fetch_row(mysqli_query($link,'SHOW CREATE TABLE '.$table));
            $return.= "\n\n".$row2[1].";\n\n"; 

            if ($num_rows !== 0) {
                $row3 = mysqli_fetch_fields($result);
                $return.= 'INSERT INTO '.$table.'( ';
                foreach ($row3 as $th) 
                { 
                    $return.= '`'.$th->name.'`, '; 
                }
                $return = substr($return, 0, -2);
                $return.= ' ) VALUES';

                for ($i = 0; $i < $num_fields; $i++) 
                {
                    while($row = mysqli_fetch_row($result))
                    {
                        $return.="\n(";
                        for($j=0; $j<$num_fields; $j++) 
                        {
                            $row[$j] = addslashes($row[$j]);
                            $row[$j] = preg_replace("#\n#","\\n",$row[$j]);
                            if (isset($row[$j])) { $return.= '"'.$row[$j].'"' ; } else { $return.= '""'; }
                            if ($j<($num_fields-1)) { $return.= ','; }
                        }
                        if (++$i_row == $num_rows) {
                            $return.= ");"; // last row
                        } else {
                            $return.= "),"; // not last row
                        }   
                    }
                }
            }
            $return.="\n\n\n";
        }

        // enable foreign keys
        $return .= 'SET FOREIGN_KEY_CHECKS=1;' . "\r\n";
        $return.= 'COMMIT;';

        //set file path
        if (!is_dir($backup_path)) {
            mkdir($backup_path, 0755, true);
        }

        //delete old file
        $old_date = date("Y-m-d", strtotime('-4 weeks', strtotime($date)));
        $old_file = $backup_path.$old_date.'-backup'.'.sql';
        if (file_exists($old_file)) unlink($old_file);

        //save file
        $handle = fopen($backup_path.$date.'-backup'.'.sql','w+');
        fwrite($handle,$return);
        fclose($handle);
    }
}

?>

我通过命令行使用mysqldump:

exec("mysqldump sourceDatabase -uUsername -p'password'  > outputFilename.sql");

然后您只需下载结果文件并完成。
