When using Transcription with an HTTP POST as the delivery method, Tropo sends a JSON-enoded string to your web server's URL. The following is an example of how to process that JSON file and write the contents to a file.
This code creates one text file per transcription, using the ID of the transcription as the filename, and putting the transcription result as the content of the file.
<?php $data = file_get_contents('php://input'); $json = json_decode($data); $file = fopen($json->result->identifier . ".txt", "w"); fwrite($file, $json->result->transcription); fclose($file); ?>
