Пример 1. Binding result set output to PHP variables
Binding columns in the result set to PHP variables is an effective
way to make the data contained in each row immediately available to
your application. The following example demonstrates how PDO allows
you to bind and retrieve columns with a variety of options and with
intelligent defaults.
<?php
function readData($dbh) {
$sql = 'SELECT name, colour, calories FROM fruit';
try {
$stmt = $dbh->prepare($sql);
$stmt->execute();
/* Bind by column number */
$stmt->bindColumn(1, $name);
$stmt->bindColumn(2, $colour);
/* Bind by column name */
$stmt->bindColumn('calories', $cals);
while ($row = $stmt->fetch(PDO_FETCH_BOUND)) {
$data = $name . "\t" . $colour . "\t" . $cals . "\n";
print $data;
}
}
catch (PDOException $e) {
print $e->getMessage();
}
}
readData($dbh);
?>
