mysql - How to use PDO to fetch results array in PHP?

Question

I'm just editing my search script after reading up on SQL injection attacks. I'm trying to get the same functionality out of my script using PDO instead of a regular mysql connection. So I've been reading other posts about PDO but am unsure. Will these two scripts give the same functionality?

With PDO:

$pdo = new PDO('mysql:host=$host; dbname=$database;', $user, $pass);
$stmt = $pdo->prepare('SELECT * FROM auction WHERE name = :name');
$stmt->bindParam(':name', $_GET['searchdivebay']);
$stmt->execute(array(':name' => $name);

With regular mysql:

$dbhost = @mysql_connect($host, $user, $pass) or die('Unable to connect to server');

@mysql_select_db('divebay') or die('Unable to select database');
$search = $_GET['searchdivebay'];
$query = trim($search);

$sql = "SELECT * FROM auction WHERE name LIKE '%" . $query . "%'";



if(!isset($query)){
echo 'Your search was invalid';
exit;
} //line 18

$result = mysql_query($trim);
$numrows = mysql_num_rows($result);
mysql_close($dbhost);

I go on with the regular example to use

while($i < $numrows){
$row = mysql_fetch_array($result);

to create an array of matching results from the database. How do I do this with PDO?

Take a look at the PDOStatement.fetchAll method. You could also use fetch in an iterator pattern.

Code sample for fetchAll, from the PHP documentation:

<?php
$sth = $dbh->prepare("SELECT name, colour FROM fruit");
$sth->execute();

/* Fetch all of the remaining rows in the result set */
print("Fetch all of the remaining rows in the result set:
");
$result = $sth->fetchAll(PDO::FETCH_ASSOC);
print_r($result);

Results:

Array
(
    [0] => Array
        (
            [NAME] => pear
            [COLOUR] => green
        )

    [1] => Array
        (
            [NAME] => watermelon
            [COLOUR] => pink
        )
)
