- __construct() : mixed
- bindParam() : bool
- Binds a PHP variable to a corresponding named (not supported by mysqli driver, see comment below) or question mark placeholder in the SQL statement that was use to prepare the statement. Unlike {@see bindValue()}, the variable is bound as a reference and will only be evaluated at the time that PDOStatement->execute() is called.
- bindValue() : bool
- Binds a value to a corresponding named (not supported by mysqli driver, see comment below) or positional placeholder in the SQL statement that was used to prepare the statement.
- execute() : Result
- Executes a prepared statement

__construct(Statement $wrappedStatement) : mixed
Parameters
- $wrappedStatement : Statement
bindParam()
Binds a PHP variable to a corresponding named (not supported by mysqli driver, see comment below) or question mark placeholder in the SQL statement that was use to prepare the statement. Unlike {@see bindValue()}, the variable is bound as a reference and will only be evaluated at the time that PDOStatement->execute() is called.
public
bindParam(mixed $param, mixed &$variable[, mixed $type = ParameterType::STRING ][, mixed $length = null ]) : bool
Parameters
- $param : mixed
-
Parameter identifier. For a prepared statement using named placeholders, this will be a parameter name of the form :name. For a prepared statement using question mark placeholders, this will be the 1-indexed position of the parameter.
- $variable : mixed
-
Name of the PHP variable to bind to the SQL statement parameter.
- $type : mixed = ParameterType::STRING
-
Explicit data type for the parameter using the ParameterType constants.
- $length : mixed = null
-
You must specify maxlength when using an OUT bind so that PHP allocates enough memory to hold the returned value.
