php示例代码之使用list函数和mysql_fetch_row函数

<?php 
  //连接参数
  $host="localhost";
  $user="root";
  $pwd="111111";
  $db="test";
  
  $linkID =mysql_connect($host,$user,$pwd); //创建一个mysql连接
  
  if(!$linkID){
  	echo "<font color='red'>unable to connect!</font>";
  }
  
  mysql_select_db($db)or die("unable to select database"); //选择一个数据库
  
  $SQL_SELECT_SYMBOLS="select * from symbols"; 
  
  $result=mysql_query($SQL_SELECT_SYMBOLS)or die("error in query :$query. ".mysql_errno()); //执行SQL语句
  
  if(mysql_num_rows($result)>0){
  	echo '<table cellpadding="10" border="1">';
  	echo '<tr><th>id</th><th>country</th><th>animal</th><th>cname</th></tr>';
  	 while(list($id,$country,$animal,$cname)=mysql_fetch_row($result)){
  	 	echo "<tr>";
  	 	echo "<td>".$id."</td>";
  	 	echo "<td>".$country."</td>";
  	    echo "<td>".$animal."</td>";
  	    echo "<td>".$cname."</td>";
  	 	echo "</tr>";
  	 }
  	 echo "</table>";
  }
  else{
  	echo "记录未找到!";
  }
  
  mysql_free_result($result); //释放记录集所占用的内存
  
  mysql_close($linkID); //关闭数据库连接
?>
