    ▪PHP过滤post,get敏感数据的实例代码      php过滤post、get传输的敏感数据的方法。 代码： 代码示例: <?php //php 批量过滤post,get敏感数据  //by www. if (get_magic_quotes_gpc()) {  $_GET = stripslashes_array($_GET);  $_POST = stripslashes_array($_POST);.........

    ▪php上传多文件与多图片的实例代码      使用php进行多文件的上传，要求实现 ： 1，在同级目录下建立upload文件夹 2，将下面代码复制到upload.php中 代码：   代码示例: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />  &l.........

    ▪php批量处理POST值的方法      学习php批量处理POST数据的方法，如下图： 需要同时删除多项，或同时修改多项记录 要点： 1，前端表单中name要加[],如:<input type="hidden" name="id[]" value="{$vo.id}"> 2，后端接受如：$id = $_POST .........

代码示例:

<?php
//php 批量过滤post,get敏感数据 
//by www.
if (get_magic_quotes_gpc()) { 
$_GET = stripslashes_array($_GET); 
$_POST = stripslashes_array($_POST); 
} 
 
function stripslashes_array(&$array) { 
while(list($key,$var) = each($array)) { 
if ($key != 'argc' && $key != 'argv' && (strtoupper($key) != $key || ''.intval($key) == "$key")) { 
if (is_string($var)) { 
$array[$key] = stripslashes($var); 
} 
if (is_array($var))  { 
$array[$key] = stripslashes_array($var); 
} 
} 
} 
return $array; 
}
