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.
The extended syntax of maxdb_stmt_bind_param() allows to give the parameters
as an array instead of a variable list of PHP variables to the function. If the array variable has not been
used before calling maxdb_stmt_bind_param(), it has to be initialized as an emtpy
array. See the examples how to use maxdb_stmt_bind_param() with extended syntax.
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().

Return values
Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.
/* 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 statement and connection */ $stmt->close();
$result = $maxdb->query("SELECT * from temp.mycity WHERE zip = '11111' OR zip = '22222'"); if ($result) { while ($row = $result->fetch_row()) { printf ("%s %s %s\n", $row[0], $row[1], $row[2]); } }
/* Clean up table CountryLanguage */ $maxdb->query("DELETE FROM temp.mycity WHERE name='Georgetown'"); $maxdb->query("DELETE FROM temp.mycity WHERE name='New Orleans'"); printf("%d Rows deleted.\n", $maxdb->affected_rows);
/* close connection */ $maxdb->close(); ?>
The above examples would produce the following output:
1 Row inserted.
1 Row inserted.
11111 Georgetown NY
22222 New Orleans LA
2 Rows deleted.
