范例

示例 #1 mysqli::get_charset() example

面向?qū)ο箫L(fēng)格

<?php
  $db = mysqli_init();
  $db->real_connect("localhost","root","","test");
  var_dump($db->get_charset());
?>

過(guò)程化風(fēng)格

<?php

  mysqli_real_connect($db, "localhost","root","","test");
  var_dump(mysqli_get_charset($db));
?>

以上例程會(huì)輸出：

  ["charset"]=>
  string(6) "latin1"
  ["collation"]=>
  string(17) "latin1_swedish_ci"
  ["dir"]=>
  string(0) ""
  ["min_length"]=>
  int(1)
  ["max_length"]=>
  int(1)
  ["number"]=>
  int(8)
  ["state"]=>
