Indeed, something I like to do when the variables are set up, really kee=
ps =
it managable.
Also an option with MDB2 prepared statment.
$db =3D new MDB2();
$db->connect('mysqli://user:pass@host/database');
$db->loadModule('Exended', null, false);
$inserts =3D array();
$stmt =3D $db->prepare(
'INSERT INTO `table` (`field`,`foo`,`bar`) VALUES (:field,:foo,:bar)',
array('text','text','integer'),
MDB2_PREPARE_MANIP);
foreach($something as $item){
//some code
$inserts[] =3D compact($bar,$foo,$field);
}
$db->extended->executeMultiple($stmt,$inserts);
