    <p>I'm trying to create a user management system class and one of my functions is to check if a value is in a column in the database. It returns nothing at all.</p> <p>Here is the relevant information:</p> <pre><code>require("opperators/connect.php"); class UserManagemen { protected $db; public function __construct(PDO $db) { $this-&gt;db = $db; } public function isInDatabase($checkIfThis, $isHere) { $stmt = $db-&gt;prepare("SELECT 1 from users WHERE $isHere = :$isHere"); $stmt-&gt;execute(array(':$isHere' =&gt; $checkIfThis)); if ($stmt-&gt;rowCount() &gt; 0) { echo "It's in the database"; } else { echo "Not in the database and you are good to go!"; } } } $usermanagement = new UserManagemen($db, null, null, null); $usermanagement-&gt;isInDatabase(Batman, username); </code></pre> <p>in connect.php: this worked in my procedural coding test.</p> <pre><code>$configurator['database'] = array( 'username' =&gt; 'root', 'password' =&gt; 'root', 'host' =&gt; 'localhost', 'db' =&gt; 'girlscouts', ); $options = array( PDO::MYSQL_ATTR_INIT_COMMAND =&gt; 'SET NAMES utf8' ); try { $db = new PDO("mysql:host={$configurator['database']['host']};dbname={$configurator['database']['db']};charset=utf8", $configurator['database']['username'], $configurator['database']['password'], $options); } catch (PDOException $ex) { die("Failed to connect to the database: " . $ex-&gt;getMessage()); } </code></pre> <p>I apologise in advance if this has been asked repeatedly, I've tried a google but returned nothing of value, possibly because I don't know what to google. I'm not big on asking for help but I'll give it a shot. </p>

    2. COAdding to what anrewsi said, it looks like php error reporting is turned off, otherwise it would have told you there was an error in your query. You could then have used php to find out what the problem was and came to the same conclusion as andrewsi.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
