register_globals.php

非常好的问答类网站代码。由PHP+MySQL编写。内容详尽。

<?php
$register_globals = @ini_get('register_globals');
$magic_quotes_gpc = @get_magic_quotes_gpc();
if(!$magic_quotes_gpc)
{
	exit('Please set magic_quotes_gpc = On in system php.ini.');
}
function daddslashes($string, $force=0)
{
	if(!$GLOBALS['magic_quotes_gpc'] || $force)
	{
		if(is_array($string))
		{
			foreach($string as $key => $val)
			{
				$string[$key] = daddslashes($val, $force);
			}
		}
		else
		{
			$string = addslashes($string);
		}
	}
	return $string;
}
function str_in($string)
{
	$string=daddslashes($string,'1');
	return $string;
}
  
if(!$register_globals || !$magic_quotes_gpc)
{
	@extract(daddslashes($HTTP_POST_VARS), EXTR_SKIP);
	@extract(daddslashes($HTTP_GET_VARS), EXTR_SKIP);
	if(!$register_globals)
	{

			${$key.'_name'} = $val['name'];
			${$key.'_size'} = $val['size'];
			${$key.'_type'} = $val['type'];
