Another way to use file_get_contents ()

$data = file_get_contents("php://input");

 Php://Input is a read-only stream that can access the raw data of the request. POST request, it is best to use php://input instead of the $HTTP _raw_post_data because it does not depend on a specific php.ini directive. And, in such a case $HTTP _raw_post_data default Nopadding, than activating always_populate_raw_post_Data potentially requires less memory. Enctype= "Multipart/form-data" when the Php://input is invalid.1,Php://Input can read the value of the specified length in the HTTP entity body, specifying the length by content-length, either post or the data submitted by the Get method. However, when the general get method submits data, the HTTP request entity body part is empty.2,Php://Input reads the same data as $http_raw_post_data, and reads only data that Content-type is not multipart/form-data.LearnNotes1，Coentent-TypeOnly if the value isApplication/X-Www-Data-urlencodedAndMultipart/Form-DataIn both cases,PhpWill not behttpThe corresponding data in the request packet is filled in with the global variable$_post2，PhpNoRecognition ofContent-TypeType, thehttpThe corresponding data in the request package is filled in with the variable$HTTP _raw_post_data3OnlyCoentent-TypeForMultipart/Form-DataThe time,PhpWill not behttpThe corresponding data in the request packet is filled inPhp://Input, otherwise the situation will be.

The above describes another way to use file_get_contents (), including aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
