PDOStatement->execute
(PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)
PDOStatement->execute — Executes a prepared statement
Beschreibung
Execute the prepared statement. If the prepared statement included parameter markers, you must either:
call PDOStatement::bindParam() to bind PHP variables to the parameter markers: bound variables pass their value as input and receive the output value, if any, of their associated parameter markers
or pass an array of input-only parameter values
Parameter-Liste
- input_parameters
-
An array of values with as many elements as there are bound parameters in the SQL statement being executed. All values are treated as PDO::PARAM_STR.
You cannot bind multiple values to a single parameter; for example, you cannot bind two values to a single named parameter in an IN() clause.
Rückgabewerte
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
