SQLite3::querySingleExecutes a query and returns a single result


public SQLite3::querySingle(string $query, bool $entireRow = false): mixed

Executes a query and returns a single result.



The SQL query to execute.


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.


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

If the query is valid but no results are returned, then null will be returned if entireRow is false, otherwise an empty array is returned.

Invalid or failing queries will return false.


Beispiel #1 SQLite3::querySingle() example

= new SQLite3('mysqlitedb.db');

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

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

string(5) "Scott"
    [username] => Scott
    [email] => scott@example.com
