file_get_contents('php://input') get file code example

Example: file_get_contents('php //input')

Actually php://input allows you to read raw POST data.

It is a less memory intensive alternative to $HTTP_RAW_POST_DATA and does not need any special php.ini directives.

php://input is not available with enctype="multipart/form-data".
