php实现简单的防止注入。
<?php
function site_addslashes($string, $force = 0)
{
!defined('MAGIC_QUOTES_GPC') && define('MAGIC_QUOTES_GPC', get_magic_quotes_gpc());
if (!MAGIC_QUOTES_GPC || $force) {
if (is_array($string)) {
foreach ($string as $key => $val) {
$string[$key] = addslashes($val, $force);
}
} else {
$string = addslashes($string);
}
}
return $string;
}
?>
