php $_GET $_POST filter sql injection program code_PHP tutorial

This article will introduce to you a php $_GET $_POST filter sql injection program code function. I hope that these functions will be helpful to your friends. This function can only filter some sensitive sql commands, such as id=1. You still need to simply filter it yourself.

The code is as follows

代码如下	复制代码
if (!get_magic_quotes_gpc()) { if (!empty($_GET)) { $_GET  = addslashes_deep($_GET); } if (!empty($_POST)) { $_POST = addslashes_deep($_POST); } $_COOKIE   = addslashes_deep($_COOKIE); $_REQUEST  = addslashes_deep($_REQUEST); } function addslashes_deep($value) { if (empty($value)) { return $value; } else { return is_array($value) ? array_map('addslashes_deep', $value) : addslashes($value); } }

Copy code

if (!get_magic_quotes_gpc())
{
if (!empty($_GET))
{
$_GET = addslashes_deep($_GET);
}
if (!empty($_POST))
{
$_POST = addslashes_deep($_POST);
}

$_COOKIE = addslashes_deep($_COOKIE);
$_REQUEST = addslashes_deep($_REQUEST);
}

function addslashes_deep($value)
{
if (empty($value))
{
return $value;
}
else
{
return is_array($value) ? array_map('addslashes_deep', $value) : addslashes($value);
}
