In addition to using LIMIT SQL statements you can also use the SQLite3 function querySingle
to retrieve a single row, or the first column.
<?php
$database = new SQLite3('mysqlitedb.db');
//Without the optional second parameter set to true, this query would return just
//the first column of the first row of results and be of the same type as columnName
$database->querySingle('SELECT column1Name FROM table WHERE column2Name=1');
//With the optional entire_row parameter, this query would return an array of the
//entire first row of query results.
$database->querySingle('SELECT column1Name, column2Name FROM user WHERE column3Name=1', true);
?>
