I'm getting the following errors when I run `cat /var/log/apache/error.log` -> PHP Notice: Undefined variable: db_connection in /var/www/html/popreport/includes/inmate.php on line 18 -> PHP Fatal error: Call to a member function query() on a non-object in /var/www/html/popreport/includes/inmate.php on line 18 When I try this in my browser I start with test.php test.php <?php require_once("./database.php"); require_once("./inmate.php"); // foreach($query as $row) // { // print_r($row) . "<br />"; // } $inmate = array(); $inmate = new Inmate($inmate); foreach($inmate as $row) { print $row->firstl_name . "<br />"; } ?> database.php <?php include("./constants.php"); try { $db_connection = new PDO("mysql:host=$host;dbname=$db_name", $db_user, $password); $db_connection->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); } catch (PDOException $e) { print "Error!: " . $e->getMessage() . "<br />"; die(); } ?> inmate.php <?php require_once("./database.php"); class Inmate { private $first_name = ''; private $last_name = ''; private $full_name = ''; private $race = ''; private $number = 0; private $facility = ''; private $type_of_transit = ''; public function __construct($inmate) { $sql = "SELECT * FROM inmate_board"; $query = $db_connection->query($sql); $result = $query->fetch(PDO::FETCH_ASSOC); foreach($result as $row) { $this->$first_name = $result['first_name']; } } public function get_property($property) { return $this->$property; } } ?> In inmate.php I also tried to change the line `$query = $db_connection->query($sql);` to `$query = global $db_connection->query($sql);` but I didn't have any luck here either. Any ideas?
