Example #1 MysqlndUhConnection::listFields() example

  <?php
 class  proxy  extends  MysqlndUhConnection  {
 public function  listFields ( $res ,  $table ,  $pattern ) {
   printf ( "%s(%s)\n" ,  __METHOD__ ,  var_export ( func_get_args (),  true ));
   $ret  =  parent :: listFields ( $res ,  $table ,  $pattern );
   printf ( "%s returns %s\n" ,  __METHOD__ ,  var_export ( $ret ,  true ));
  return  $ret ;
 }
}
 mysqlnd_uh_set_connection_proxy (new  proxy ());

 $mysql  =  mysql_connect ( "localhost" ,  "root" ,  "" );
 mysql_select_db ( "test" ,  $mysql );
 mysql_query ( "DROP TABLE IF EXISTS test_a" ,  $mysql );
 mysql_query ( "CREATE TABLE test_a(id INT, col1 VARCHAR(255))" ,  $mysql );
 $res  =  mysql_list_fields ( "test" ,  "test_a" ,  $mysql );
 printf ( "num_rows = %d\n" ,  mysql_num_rows ( $res ));
while ( $row  =  mysql_fetch_assoc ( $res ))
  var_dump ( $row );
 ?>

以上例程会输出：

proxy::listFields(array (
  0 => NULL,
  1 => 'test_a',
  2 => '',
))
proxy::listFields returns NULL
num_rows = 0
