范例

Example #1 MysqlndUhConnection::setServerOption() example

  <?php
 function  server_option_to_string ( $option ) {
  $ret  =  'unknown' ;
 switch ( $option ) {
  case  MYSQLND_UH_SERVER_OPTION_MULTI_STATEMENTS_ON :
    $ret  =  'MYSQLND_UH_SERVER_OPTION_MULTI_STATEMENTS_ON' ;
   break;
  case  MYSQLND_UH_SERVER_OPTION_MULTI_STATEMENTS_OFF :
    $ret  =  'MYSQLND_UH_SERVER_OPTION_MULTI_STATEMENTS_ON' ;
   break;
 }
 return  $ret ;
}

class  proxy  extends  MysqlndUhConnection  {
 public function  setServerOption ( $res ,  $option ) {
   printf ( "%s(%s)\n" ,  __METHOD__ ,  var_export ( func_get_args (),  true ));
   printf ( "Option '%s' set\n" ,  server_option_to_string ( $option ));
   $ret  =  parent :: setServerOption ( $res ,  $option );
   printf ( "%s returns %s\n" ,  __METHOD__ ,  var_export ( $ret ,  true ));
  return  $ret ;
 }
}
 mysqlnd_uh_set_connection_proxy (new  proxy ());
 $mysqli  = new  mysqli ( "localhost" ,  "root" ,  "" ,  "test" );
 $mysqli -> multi_query ( "SELECT 1; SELECT 2" );
 ?>

以上例程会输出：

proxy::setServerOption(array (
  0 => NULL,
  1 => 0,
))
Option 'MYSQLND_UH_SERVER_OPTION_MULTI_STATEMENTS_ON' set
proxy::setServerOption returns true
