PDOStatement::execute

(PHP 5 >= 5.1.0, PECL pdo >= 0.1.0)

PDOStatement::execute — Executes a prepared statement

Описание

bool PDOStatement::execute ([ array $input_parameters ] )

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

Список параметров

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.

You cannot bind more values than specified; if more keys exist in input_parameters than in the SQL specified in the PDO::prepare(), then the statement will fail and an error is emitted.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

5.2.0 The keys from input_parameters must match the ones declared in the SQL. Before PHP 5.2.0 this was silently ignored.
