How to receive binary streams and generate files in PHP

Code for PHP to receive binary streams and generate files

<?php  
    /** Binary stream generation file 
    * $_post cannot interpret binary streams, requires $GLOBALS [' http_raw_post_data '] or php://input 
    * $GLOBALS [' Http_raw_post_data '] and php://input are not available for Enctype=multipart/form-data 
    * @param    String  $file   The file path to be generated 
    * @return   boolean
    /function Binary_to_file ($file) {  
        $content = $GLOBALS [' Http_raw_post_ DATA '];  Requires php.ini to set  
        if (empty ($content)) {  
            $content = file_get_contents (' php://input ');    Do not need php.ini settings, memory pressure small  
        }  
        $ret = File_put_contents ($file, $content, true);  
        return $ret;  
    }
