php通用防注入程序 推荐

复制代码 代码如下:
function jk1986_checksql()
{
$bad_str = "and|select|update|'|delete|insert|*";
$bad_Array = explode("|",$bad_str);

foreach ($bad_Array as $bad_a)
{
foreach ($_GET as $g)
{
if (substr_count(strtolower($g),$bad_a) > 0)
{
echo "";
exit();
}
}
}



foreach ($bad_Array as $bad_a)
{
foreach ($_POST as $p)
{
if (substr_count(strtolower($p),$bad_a) > 0)
{
echo "";
exit();
}
}
}



foreach ($bad_Array as $bad_a)
{
foreach ($_cookie as $co)
{
if (substr_count(strtolower($co),$bad_a) > 0)
{
echo "";
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
