Question

I created this code:

$statement = $db->prepare("SELECT * FROM phptech_contact");
$statement->execute();
$result = $statement->result_metadata();
$object = $result->fetch_object();

print_r( $object );

When I run it, it doesn’t work. Can anybody tell me why it doesn’t work?

I have 20 rows in this table so data should be returned.

From http://ch.php.net/manual/en/mysqli-stmt.result-metadata.php

Note: The result set returned by mysqli_stmt_result_metadata() contains only metadata. It does not contain any row results. The rows are obtained by using the statement handle with mysqli_stmt_fetch().

As long as you don’t need this meta data you don’t need to call this method.

$statement = $db->prepare("SELECT fld1, fld2 FROM phptech_contact");
$statement->execute();
$stmt->bind_result($fld1, $fld2);

while ($stmt->fetch()) {
    echo "$fld1 and $fld2<br />";
}

But I really dislike the mysqli extension. PDO is much cooler … 😉

$db = new PDO('...');
$stmt = $db->prepare("SELECT fld1, fld2 FROM phptech_contact");
$stmt->execute();

while ($obj = $stmt->fetchObject()) {
    // ...
}

or

$objs = stmt->fetchAll(PDO::FETCH_OBJ);
