下面一款防止php页面给sql注入的一个程序代码,有需要的朋友可参考,以下代码实现过滤php的$_GET 和$_POST参数.
php防注入过滤客户提交$_GET 和$_POST参数实例代码如下:
-
-
-
- function Add_S($array)
- {
- foreach($array as $key=>$value)
- {
- if(!is_array($value))
- {
- $value = get_magic_quotes_gpc()?$value:addslashes($value);
- $array[$key]=filterHtml($value);
- }
- Else
- {
- Add_S($array[$key]);
- }
- }
- return $array;
- }
- function glstr($var) {
-
- if (is_array($var)) {
- return Add_S($var);
- }
- elseif(strlen($var)){
- $var = get_magic_quotes_gpc()?$var:addslashes($var);
-
- $var = filterHtml($var);
- }
- return $var;
- }
- function filterHtml($html)
- {
- $farr = array(
- "/<!DOCTYPE([^>]*?)>/eis",
- "/<(/?)(html|body|head|link|meta|base|input)([^>]*?)>/eis",
- "/<(script|i?frame|style|title|form)(.*?)</\1>/eis",
- "/(<[^>]*?s+)on[a-z]+s*?=("|')([^\2]*)\2([^>]*?>)/isU",
- "/s+/",
- );
- $tarr = array(
- "",
- "",
- "",
- "\1\4",
- " ",
- );
- $html = preg_replace( $farr,$tarr,$html);
- return $html;
- }
- if (sizeof($_GET)) {
- foreach($_GET as $key => $value) {
- $_GET[$key] = glstr($value);
- }
-
- }
- if (sizeof($_POST)) {
- foreach($_POST as $key => $value) {
- $_POST[$key] = glstr($value);
- }
- }
