PHP字符串中特殊符号的过滤方法

分类:php

 合适入库前数据处理:

function dowith_sql($str)
{
   $str = str_replace("and","",$str);
   $str = str_replace("execute","",$str);
   $str = str_replace("update","",$str);
   $str = str_replace("count","",$str);
   $str = str_replace("chr","",$str);
   $str = str_replace("mid","",$str);
   $str = str_replace("master","",$str);
   $str = str_replace("truncate","",$str);
   $str = str_replace("char","",$str);
   $str = str_replace("declare","",$str);
   $str = str_replace("select","",$str);
   $str = str_replace("create","",$str);
   $str = str_replace("delete","",$str);
   $str = str_replace("insert","",$str);
   $str = str_replace("'","",$str);
   $str = str_replace(""","",$str);
   $str = str_replace(" ","",$str);
   $str = str_replace("or","",$str);
   $str = str_replace("=","",$str);
   $str = str_replace(" ","",$str);
   //echo $str;
   return $str;
}
