php通用防注入程序 推荐_PHP教程

复制代码 代码如下:

function jk1986_checksql()
{
$bad_str = "and|select|update|'|delete|insert|*";
$bad_Array = explode("|",$bad_str);
/** 过滤Get参数 **/
foreach ($bad_Array as $bad_a)
{
foreach ($_GET as $g)
{
if (substr_count(strtolower($g),$bad_a) > 0)
{
echo "<script>alert('诡异字符,请不要尝试注入本站! 作者:Jk1986 QQ:414028660');location.href='index.php';</script>";
exit();
}
}
}

/** 过滤Post参数 **/

foreach ($bad_Array as $bad_a)
{
foreach ($_POST as $p)
{
if (substr_count(strtolower($p),$bad_a) > 0)
{
echo "<script>alert('诡异字符,请不要尝试注入本站! 作者:Jk1986 QQ:414028660');location.href='index.php';</script>";
exit();
}
}
}

/** 过滤Cookies参数 **/

foreach ($bad_Array as $bad_a)
{
foreach ($_COOKIE as $co)
{
if (substr_count(strtolower($co),$bad_a) > 0)
{
echo "<script>alert('诡异字符,请不要尝试注入本站! 作者:Jk1986 QQ:414028660');location.href='index.php';</script>";
exit();
}
}
}
}

呵呵 类似asp和asp.net 思路一样,目的就是让懒来提高效率 .88
