Example 1770. 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);
?>

The above example will output:
