In most cases inserting multiple records with one Insert statement is much faster in MySQL than inserting records with for foreach loop in PHP   Let s assume  column1 and  column2 are arrays with same size posted by html form   You can create your query like this    lt  php      query    INSERT INTO TABLE   column1    column2   VALUES         query parts   array        for  x 0   x lt count  column1    x              query parts             column1  x              column2  x                    echo  query    implode       query parts     gt    If data is posted for two records the query will become      INSERT INTO TABLE  column1  column2  VALUES   data    data      data    data

If you would like to insert multiple values lets say from multiple inputs that have different post values but the same table to insert into then simply use   mysql query  INSERT INTO  table   a b c d e f g  VALUES     a    b    c    d    e    f    g       a    b    c    d    e    f    g       a    b    c    d    e    f    g     or die  mysql error        Inserts 3 times in 3 different rows

While inserting multiple rows with a single INSERT statement is generally faster  it leads to a more complicated and often unsafe code  Below I present the best practices when it comes to inserting multiple records in one go using PHP  To insert multiple new rows into the database at the same time  one needs to follow the following 3 steps   Start transaction  disable autocommit mode  Prepare INSERT statement Execute it multiple times  Using database transactions ensures that the data is saved in one piece and significantly improves performance  How to properly insert multiple rows using PDO PDO is the most common choice of database extension in PHP and inserting multiple records with PDO is quite simple   pdo   new  PDO  quot mysql host localhost dbname test charset utf8mb4 quot    user    password          PDO  ATTR ERRMODE   gt   PDO  ERRMODE EXCEPTION       PDO  ATTR EMULATE PREPARES   gt  false         Start transaction  pdo- gt beginTransaction        Prepare statement  stmt    pdo- gt prepare  INSERT      INTO  pxlot   realname email address phone status regtime ip       VALUES                        Perform execute   inside a loop    Sample data coming from a fictitious data set  but the data can come from anywhere foreach   dataSet as  data           All seven parameters are passed into the execute   in a form of an array      stmt- gt execute   data  name     data  email     data  address    getPhoneNo  data  name      0    data  regtime     data  ip            Commit the data into the database  pdo- gt commit     How to properly insert multiple rows using mysqli The mysqli extension is a little bit more cumbersome to use but operates on very similar principles  The function names are different and take slightly different parameters  mysqli report MYSQLI REPORT ERROR   MYSQLI REPORT STRICT    mysqli   new  mysqli  localhost    user    password    database     mysqli- gt set charset  utf8mb4        Start transaction  mysqli- gt begin transaction        Prepare statement  stmt    mysqli- gt prepare  INSERT      INTO  pxlot   realname email address phone status regtime ip       VALUES                        Perform execute   inside a loop    Sample data coming from a fictitious data set  but the data can come from anywhere foreach   dataSet as  data           mysqli doesn t accept bind in execute yet  so we have to bind the data first        The first argument is a list of letters denoting types of parameters  It s best to use  s  for all unless you need a specific type        bind param doesn t accept an array so we need to unpack it first using            stmt- gt bind param  sssssss        data  name     data  email     data  address    getPhoneNo  data  name      0    data  regtime     data  ip           stmt- gt execute          Commit the data into the database  mysqli- gt commit     Performance Both extensions offer the ability to use transactions  Executing prepared statement with transactions greatly improves performance  but it s still not as good as a single SQL query  However  the difference is so negligible that for the sake of conciseness and clean code it is perfectly acceptable to execute prepared statements multiple times  If you need a faster option to insert many records into the database at once  then chances are that PHP is not the right tool
