echo $_SERVER['SCRIPT_FILENAME']."?".$_SERVER['QUERY_STRING'];

11.mysql_fetch_row() 和mysql_fetch_array之间有什么区别？<br>mysql_fetch_row() 从和指定的结果标识关联的结果集中取得一行数据并作为数组返回。每个结果的列储存在一个数组的单元中，偏移量从 0 开始。mysql_fetch_array() 是 mysql_fetch_row() 的扩展版本。除了将数据以数字索引方式储存在数组中之外，还可以将数据作为关联索引储存，用字段名作为键名。

12.判断以下输出

 $str1 = null;
 $str2 = false;
 echo $str1==$str2 ? '<span 相等</span>' : '<span 不相等</span>';  //相等
 $str3 = '<span </span>';
 $str4 = 0;
 echo $str3==$str4 ? '<span 相等</span>' : '<span 不相等</span>';  //相等
 $str5 = 0;
 $str6 = '<span 0</span>';
 echo $str5===$str6 ? '<span 相等</span>' : '<span 不相等</span>';  //不相等

13.写出以下结果

<span <?</span>php
 $test = '<span aaaaaa</span>';
 $abc = & $test;
 unset($test);
 echo $abc;  <span //aaaaaa</span>
 <span ?></span>
