I am looking for a way to sync MySql database across different environments (local and production) synced by using PhpMyAdmin. Thus looking for the ability to find diffs and then apply the one's we would like to.

Since the inbuilt Synchronize feature has been discontinued. What is the best way to do this in PhpMyAdmin?

Even if via sql queries would work.

Thanks.

你可以很容易地在 php 中做到这一点......这是我使用的脚本

同步

$account_tables = $Db_stage->run("SELECT table_name, table_rows FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '".$Init->container["Config"]->dbName."' ORDER BY table_name");
$production_tables = $Db_production->run("SELECT table_name, table_rows FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '".$dbName."' ORDER BY table_name");

foreach ($account_tables as $account_table){        
    $dbDrop = "/usr/bin/mysql -u ".$Init->container["Config"]->dbUser." -p".$Init->container["Config"]->dbPassword." ".$Init->container["Config"]->dbName." -e 'drop table `".$account_table["table_name"]."`'";
    echo "DROP ".$account_table["table_name"]."<br/>";
    //echo $dbDrop."<br/>";
    exec($dbDrop);
    flush();
}

foreach ($production_tables as $production_table){
    echo "SETUP ".$production_table["table_name"].'<br/>';
    $dbDump = '/usr/bin/mysqldump --lock-tables=false --single-transaction --skip-add-locks -h '.$dbHost.' -u '.$dbUser.' -p'.$dbPassword.' '.$dbName.' '.$production_table["table_name"].' > '.$Init->container["Config"]->dirPublic.'system/sync/db/'.$production_table["table_name"].'.sql';
    //echo $dbDump."<br/>";
    exec($dbDump);
    exec('/usr/bin/mysql --user='.$Init->container["Config"]->dbUser.' --password='.$Init->container["Config"]->dbPassword.' '.$Init->container["Config"]->dbName.' < '.$Init->container["Config"]->dirPublic.'system/sync/db/'.$production_table["table_name"].'.sql');    
    flush();
}

和差异

$account_tables = $Init->container["Db"]->run("SELECT table_name, table_rows FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_SCHEMA = '".$Init->container["Config"]->dbName."' ORDER BY table_name");
