maxdb_stmt_bind_param is used to bind variables for the
parameter markers in the SQL statement that was passed to
maxdb_prepare.
The string types contains one or more characters which specify
the types for the corresponding bind variables.
Variables for SELECT INTO SQL statements can also be bound using maxdb_stmt_bind_param.
Parameters for database procedures can be bound using maxdb_stmt_bind_param. See the
examples how to use maxdb_stmt_bind_param in this cases.
If a variable bound as INTO variable to a SQL statement was used before, the content of this variable
is overwritten by the data of the SELECT INTO statement. A reference to this variable will be invalid after a call to
maxdb_stmt_bind_param.
For INOUT parameters of database procedures the content of the bound INOUT variable is overwritten by the output
value of the database procedure. A reference to this variable will be invalid after a call to
maxdb_stmt_bind_param.

Example

query ("CREATE TABLE temp.mycity LIKE hotel.city");
$maxdb->query ("INSERT INTO temp.mycity SELECT * FROM hotel.city");
$stmt = $maxdb->prepare("INSERT INTO temp.mycity VALUES (?, ?, ?)");
$stmt->bind_param('sss', $zip, $name, $state);
$zip = '11111';
$name = 'Georgetown';
$state = 'NY';
/* execute prepared statement */
$stmt->execute();
printf("%d Row inserted.\n", $stmt->affected_rows);
/* close statement and connection */
$stmt->close();
/* Clean up table CountryLanguage */
$maxdb->query("DELETE FROM temp.mycity WHERE name='Georgetown'");
printf("%d Row deleted.\n", $maxdb->affected_rows);
/* close connection */
$maxdb->close();
