Programming PHP

Storing the row
The fetchInto( ) method also gets the next row, but stores it into the array variable
passed as a parameter:
$success = $result->fetchInto(array, [mode]);
Like fetchRow( ), fetchInto( ) returns NULL if there is no more data, or DB_ERROR if an
error occurs.
The idiom to process all results looks like this with fetchInto( ):
while ($success = $result->fetchInto($row)) {
if (DB::isError($success)) {
die($success->getMessage( ));
}
// do something with the row
}
Inside a row array
Just what are these rows that are being returned? By default, they’re indexed arrays,
where the positions in the array correspond to the order of the columns in the
returned result. For example:
$row = $result->fetchRow( );
if (DB::isError($row)) {
die($row->getMessage( ));
}
var_dump($row);
array(3) {
[0]=>
string(5) "Dr No"
[1]=>
string(4) "1962"
[2]=>
string(12) "Sean Connery"
}
You can pass a mode parameter to fetchRow( ) or fetchInto( ) to control the format of
the row array. The default behavior, shown previously, is specified with DB_
FETCHMODE_ORDERED.
The fetch mode DB_FETCHMODE_ASSOC creates an array whose keys are the column
names and whose values are the values from those columns:
$row = $result->fetchRow(DB_FETCHMODE_ASSOC);
if (DB::isError($row)) {
die($row->getMessage( ));
}
var_dump($row);
array(3) {
["title"]=>
string(5) "Dr No"
["year"]=>
