Answer 2

Phpmyadmin has inbuilt functionality to copy tables from one database to another. Otherwise you can go with Pekka or export table then import table.

Answer 3

exec('mysqldump --user=username --password="password" --host=hostname --database=database table1 table2 > databasedump.sql');

exec('mysql --user=username --password="password" --host=hostname --database=database < databasedump.sql');

Answer 4

As it seems that nobody answered the initial question actually, here is my PHP script to backup a table from a remote MySQL server to a local MySQL server:

function backup_remote_table (
    $remote_db_host, $remote_login, $remote_password, $remote_db_name, $remote_table_name,
    $local_db_host, $local_login, $local_password, $local_db_name, $local_table_name
) {
    // Generating names with time stamps for local database and/or local table, if not available
    if ($local_table_name) {
        $applied_local_table_name = $local_table_name;
    } else {
        $applied_local_table_name = $remote_table_name;
    }
    if ($local_db_name) {
        $applied_local_db_name = $local_db_name;
        if (!$local_table_name) {
          $applied_local_table_name .= date_format(date_create(), '_Y_m_d_H_i_s');
        }
    } else {
        $applied_local_db_name = $remote_db_name . date_format(date_create(), '_Y_m_d_H_i_s');
    }

    // Local server connection
    $local_db_server = mysql_connect($local_db_host, $local_login, $local_password);
    $local_db_server = mysql_query("CREATE DATABASE IF NOT EXISTS " . $applied_local_db_name, $local_db_server);
    mysql_select_db($applied_local_db_name, $local_db_server);

    // Remote server connection
    $remote_db_server = mysql_connect($remote_db_host, $remote_login, $remote_password);
    mysql_select_db($remote_db_name, $remote_db_server);

    // Getting remote table data
    $result_remote_table_info = mysql_query("SHOW CREATE TABLE " . $remote_table_name, $remote_db_server);
    $remote_table_info = mysql_fetch_array($result_remote_table_info);
    $remote_table_description = substr($remote_table_info[1], 13);

    // Creating local table
    $sql_new_table = "CREATE TABLE IF NOT EXISTS " . $applied_local_db_name . "." . $remote_table_description;
    mysql_query($sql_new_table, $local_db_server);

    // Getting all records of remote table
    $result_remote_table_data = mysql_query("SELECT * FROM " . $table_name, $remote_db_server);
    while ($remote_table_row = mysql_fetch_array($result_remote_table_data, MYSQL_ASSOC)){
        // Browsing records of remote table
        $sql_new_row = "INSERT INTO $applied_local_db_name.$applied_local_table_name (".implode(", ",array_keys($remote_table_row)).") VALUES (";
        $extra_sql = "";
        foreach (array_values($remote_table_row) as $value) {
            if ($extra_sql != "") {
                $extra_sql .= ",";
            }
            $extra_sql .= "'";
            $extra_sql .= mysql_real_escape_string($value);
            $extra_sql .= "'";
        }
        $sql_new_row .= $extra_sql . ")";
        // Adding record to local table
        $result_new_table_row = mysql_query($sql_new_row, $local_db_server);
    }
    mysql_free_result($result_remote_table_data);

    return;
}

The solution above is not mine, I got it here, with minor changes.

Answer 5

I'll put this answer up for anyone else looking for help.

If you don't have access to SSH then you can use PhpMyAdmin.

Simply:

1. browse to the table you want to move
2. Click the Operations tab
3. Use the MOVE or COPY to database function

If you come across privilege problems, you can temp grant a user Global permissions or add the same user to both databases.

Answer 6

If you need to copy the table on the same server you can use this code:

USE db2;

CREATE TABLE table2 LIKE db1.table1;

INSERT INTO table2  
    SELECT * FROM db1.table1;

It's copy+pasted from here: codingforums.com

It's not my solution, but I find it useful.
