bool bind_param ( string types, mixed &var1 [, mixed &...] )

}

mysqli_stmt_bind_param() is used to bind variables for the parameter markers in the SQL statement that was passed to mysqli_prepare(). The string types contains one or more characters which specify the types for the corresponding bind variables

bcorresponding variable is a blob and will be send in packets

Замечание: If data size of a variable exceeds max. allowed packet size (max_allowed_packet), you have to specify b in types and use mysqli_stmt_send_long_data() to send the data in packets.

The number of variables and length of string types must match the parameters in the statement.

/* close statement and connection */
mysqli_stmt_close($stmt);

/* Clean up table CountryLanguage */
mysqli_query($link, "DELETE FROM CountryLanguage WHERE Language='Bavarian'");
