Several ways to get post parameters in php

Several ways for PHP to get post parameters

1. $_POST['paramName'] can only receive data submitted by Content-Type: application/x-www-form-urlencoded

2. file_get_contents( "php://input") Applicable to most types of Content-type

php://input allows reading the raw data of POST. It puts less pressure on memory than $HTTP_RAW_POST_DATA and does not require any special php.ini settings. php://input cannot be used with enctype="multipart/form-data".

3. $GLOBALS['HTTP_RAW_POST_DATA']; always generates $HTTP_RAW_POST_DATA variable containing the original POST data. This variable is only generated when data of an unrecognized MIME type is encountered. $HTTP_RAW_POST_DATA is not available for enctype="multipart/form-data" form data.

If the posted data is not recognized by PHP, you can use $GLOBALS['HTTP_RAW_POST_DATA'] to receive it, such as text/xml or soap, etc.
