mysql mysql_real_escape_string() 转义问题

Answer 1

mysql_real_escape_string是将所有带有特殊字符进行转义
下列字符受影响：
x00
n
r

'
"
x1a
假如你要转义，请将查询参数转义了再带入sql ，如
$aid = mysql_real_escape_string("14218902787457024");
$date = mysql_real_escape_string("20170302");
select orderid from order where date = $date AND aid ='$aid'
