范例

Example #1 cubrid_data_seek() example

  <?php
$conn  =  cubrid_connect ( "127.0.0.1" ,  33000 ,  "demodb" );

 $req  =  cubrid_execute ( $conn ,  "SELECT * FROM code" );
 cubrid_data_seek ( $req ,  0 );

 $result  =  cubrid_fetch_row ( $req );
 var_dump ( $result );

 cubrid_data_seek ( $req ,  2 );
 $result  =  cubrid_fetch_row ( $req );
 var_dump ( $result );

 cubrid_data_seek ( $req ,  4 );
 $result  =  cubrid_fetch_row ( $req );
 var_dump ( $result );

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

以上例程会输出：

array(2) {
  [0]=>
  string(1) "X"
  [1]=>
  string(5) "Mixed"
}
array(2) {
  [0]=>
  string(1) "M"
  [1]=>
  string(3) "Man"
}
array(2) {
  [0]=>
  string(1) "S"
  [1]=>
  string(6) "Silver"
}
