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
