本文实例讲述了PHP数据的提交与过滤基本操作。分享给大家供大家参考，具体如下：

1、php提交数据过滤的基本原则

1）提交变量进数据库时，我们必须使用addslashes()进行过滤，像我们的注入问题，一个addslashes()也就搞定了。其实在涉及到变量取值时，intval()函数对字符串的过滤也是个不错的选择。

2）在php.ini中开启magic_quotes_gpc和magic_quotes_runtime。magic_quotes_gpc可以把get,post,cookie里的引号变为斜杠。

magic_quotes_runtime对于进出数据库的数据可以起到格式话的作用。其实，早在以前注入很疯狂时，这个参数就很流行了。

3）在使用系统函数时，必须使用escapeshellarg(),escapeshellcmd()参数去过滤，这样你也就可以放心的使用系统函数。

4）对于跨站，strip_tags(),htmlspecialchars()两个参数都不错，对于用户提交的的带有html和php的标记都将进行转换。比如尖括号"<"就将转化为 "<"这样无害的字符。

$new = htmlspecialchars("<a href='test'>Test</a>", ENT_QUOTES); strip_tags($text,);

5）对于相关函数的过滤，就像先前的include(),unlink,fopen()等等，只要你把你所要执行操作的变量指定好或者对相关字符过滤严密，我想

这样也就无懈可击了。

2、PHP简单的数据过滤

1）入库: trim($str),addslashes($str)

2）出库: stripslashes($str)

3）显示: htmlspecialchars(nl2br($str))
