Ich verwende derzeit die Yelp API v3 und teste einige ihrer Beispielcode. Ich habe noch nie PHP benutzt, also ist es ziemlich verwirrend, aber ich frage mich nur, wo ich den Begriff und den Ort gleich der Benutzereingabe in diesem Skript einstellen würde? Angenommen, ich habe eine Eingabe für Term und Ort in html, wo in diesem Skript $ term = inputTerm und $ location = inputLocation sind?Wie benutze ich Yelp v3 Search API Beispiel in PHP
`#!/usr/bin/php

* Yelp Fusion API code sample.

* This program demonstrates the capability of the Yelp Fusion API

*
* Please refer to http://www.yelp.com/developers/v3/documentation

* Sample usage of the program:
* `php sample.php --term="dinner" --location="San Francisco, CA"`
