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 "";
exit();
}
}
}

/** 过滤Post参数 **/

foreach ($bad_Array as $bad_a)
{
foreach ($_POST as $p)

exit();
}
}

foreach ($_COOKIE as $co)
