php addslashes 利用递归实现使用反斜线引用字符串

<?php
function addslashes_deep($value)
{
//史上最经典的递归，一行搞定
return is_array($value) ? array_map('addslashes_deep', $value) : addslashes($value);
}

//测试数据
$_POST['STR'] = "'fanglor ' is \\ a boy >'";
$_GET['STR1'] = 'fanglor " is \\ a boy >';

echo '当前get_magic_quotes_gpc为 '.get_magic_quotes_gpc();
echo "<br/>";

//判断当前是否开启get_magic_quotes_gpc
if (!get_magic_quotes_gpc()){
$_POST = addslashes_deep($_POST);
$_GET = addslashes_deep($_GET);
$_COOKIE = addslashes_deep($_COOKIE);
}

//打印结果
var_dump ($_POST);
echo "<br/>";
var_dump ($_GET);

?>

打印结果：
当前get_magic_quotes_gpc为 0
array(1) { ["STR"]=> string(30) "\\'fanglor \\' is \\\\ a boy >\\'" }
array(1) { ["STR1"]=> string(26) "fanglor \\" is \\\\ a boy >" }
