file_get_contents（）的另一种使用方法，filegetcontents

今天在网上看到一篇挺不错的文章，拿过来保存学习一下。本文源地址为：http://www.kuitao8.com/20140727/2867.shtml
$data = file_get_contents("php://input");
<span class="php-hl-code">    <span class="php-hl-identifier">php<span class="php-hl-code">:<span class="php-hl-comment">//<span class="php-hl-comment">input 是个可以访问请求的原始数据的只读流。 POST 请求的情况下，最好使用 php://input 来代替 $HTTP_RAW_POST_DATA，因为它不依赖于特定的 php.ini 指令。 而且，这样的情况下 $HTTP_RAW_POST_DATA 默认没有<span id="12_nwp">填充， 比激活 always_populate_raw_post_<span id="13_nwp">data 潜在需要更少的内存。 enctype="multipart/form-data" 的时候 php://input 是无效的。 
    
 
<span class="php-hl-number">1<span class="php-hl-code">, <span class="php-hl-identifier">php<span class="php-hl-code">:<span class="php-hl-comment">//<span class="php-hl-comment">input 可以读取http entity body中指定长度的值,由Content-Length指定长度,不管是POST方式或者GET方法提交过来的数据。但是，一般GET方法提交数据 时，http request entity body部分都为空。 
<span class="php-hl-number">2<span class="php-hl-code">,<span class="php-hl-identifier">php<span class="php-hl-code">:<span class="php-hl-comment">//<span class="php-hl-comment">input 与$HTTP_RAW_POST_DATA读取的数据是一样的，都只读取Content-Type不为multipart/form-data的数据。<span class="php-hl-code">
