Lots of data
Lists of data rows
<?php
$query = "SELECT * FROM `contact` WHERE `age` > ? AND `gender` = ?"; $stmt = $pdo->prepare($query); $stmt->bindParam(1, $cleanAge); $stmt->bindParam(2, $cleanGender); $stmt->execute();
// A resultset of 63,992 entries stored in an array!!! $resultList = $stmt->fetchAll();
<?php
public function getSelectedContacts($age, $gender) { $resultSet = $this->tableGateway->select(array( 'age' => $age, 'gender' => $gender, )); return $resultSet; }
