Executes a query and returns a single result.

Parameters

query: The SQL query to execute.
entireRow: By default, querySingle() returns the value of the first column returned by the query. If entireRow is true, then it returns an array of the entire first row.

Return Values

Returns the value of the first column of results or an array of the entire first row (if entireRow is true).

<?php
$db = new SQLite3('mysqlitedb.db');

print_r($db->querySingle('SELECT username, email FROM user WHERE userid=1', true));
?>
