php中$_POST与php://input的区别实例分析,_post实例分析
本文实例分析了php中$_POST与php://input的区别。分享给大家供大家参考。具体分析如下:
$_POST 与 php教程://input可以取到值,$HTTP_RAW_POST_DATA 为空
$_POST 以关联数组方式组织提交的数据,并对此进行编码处理,如urldecode,甚至编码转换
php://input 也可以实现此这个功能可以获得POST的原始数据。
代码
复制代码 代码如下:
echo file_get_contents( "php://input ");
实例
复制代码 代码如下:
post.php
复制代码 代码如下:
php://input 允许读取 POST 的原始数据。和 $HTTP_RAW_POST_DATA 比起来,它给内存带来的压力较小,并且不需要任何特殊的 php.ini 设置。php://input 不能用于 enctype="multipart/form-data"。
php的$_POST:
$_POST 变量是一个数组,内容是由 HTTP POST 方法发送的变量名称和值.
$_POST 变量用于收集来自 method="post" 的表单中的值,从带有 POST 方法的表单发送的信息,对任何人都是不可见的(不会显示在浏览器的地址栏),并且对发送信息的量也没有限制.
html
复制代码 代码如下:
welcome.php
复制代码 代码如下:
Welcome .
You are years old!
通过 HTTP POST 发送的变量不会显示在 URL 中,变量没有长度限制.
希望本文所述对大家的php程序设计有所帮助。

H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.
