php示例代码之使用MySQLi接口

      <?php 

  //连接参数

  $host="localhost";

  $user="root";

  $pwd="111111";

  $db="test";

  

  $linkID =mysqli_connect($host,$user,$pwd,$db); //创建一个mysql连接

  

  if(!$linkID){

  	echo "<font color='red'>unable to connect!</font>";

  }

  

  $SQL_SELECT_SYMBOLS="select * from symbols"; 

  

  $result=mysqli_query($linkID,$SQL_SELECT_SYMBOLS)or die("error in query :$query. ".mysql_errno()); //执行SQL语句

  

  if(mysqli_num_rows($result)>0){

  	echo '<table cellpadding="10" border="1">';

  	echo '<tr><th>id</th><th>country</th><th>animal</th><th>cname</th></tr>';

  	 while($row=mysqli_fetch_row($result)){

  	 	echo "<tr>";

  	 	echo "<td>".$row[0]."</td>";

  	 	echo "<td>".$row[1]."</td>";

  	    echo "<td>".$row[2]."</td>";

  	    echo "<td>".$row[3]."</td>";

  	 	echo "</tr>";

  	 }

  	 echo "</table>";

  }

  else{

  	echo "记录未找到!";

  }

  

  mysqli_free_result($result); //释放记录集所占用的内存

  

  mysqli_close($linkID); //关闭数据库连接

?>
