范例

Example #1 cubrid_fetch_object() example

 <?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$res = cubrid_execute($conn, "SELECT * FROM code");

var_dump(cubrid_fetch_object($res));

// if you want to operate LOB object, you can use cubrid_fetch_object($res, CUBRID_LOB)

class demodb_code {
    public $s_name = null;
    public $f_name = null;

    public function toString() {
        var_dump($this);
    }
}

var_dump(cubrid_fetch_object($res, "demodb_code"));

// if you want to operate LOB object, you can use cubrid_fetch_object($res, "demodb_code", CUBRID_LOB)

class demodb_code_construct extends demodb_code {
    public function __construct($s, $f) {
        $this->s_name = $s; 
        $this->f_name = $f; 
    }   
}

var_dump(cubrid_fetch_object($res, 'demodb_code_construct', array('s_name', 'f_name')));

// if you want to operate LOB object, you can use cubrid_fetch_object($res, 'demodb_code_construct', array('s_name', 'f_name'), CUBRID_LOB)


var_dump(cubrid_fetch_object($res));

cubrid_close_request($res);
cubrid_disconnect($conn);
?>

以上例程会输出：

object(stdClass)#1 (2) {
  ["s_name"]=>
  string(1) "X"
  ["f_name"]=>
  string(5) "Mixed"
}
object(demodb_code)#1 (2) {
  ["s_name"]=>
  string(1) "W"
  ["f_name"]=>
  string(5) "Woman"
}
object(demodb_code_construct)#1 (2) {
  ["s_name"]=>
  string(6) "s_name"
  ["f_name"]=>
  string(6) "f_name"
}
object(stdClass)#1 (2) {
  ["s_name"]=>
  string(1) "B"
  ["f_name"]=>
  string(6) "Bronze"
}
