Question

I’m doing a query to the Alexa API which, for some unknown reason, will occasionally fail. When it does fail, I want to automatically retry the query, up to 10 times.

When it fails, the response returned by the API contains the substring AuthFailure.

What kind of loop can I do that will retry the query until either the response returned does not contain the substring AuthFailure or 10 retries have been attempted?

Answer 1

You could do this with a for loop.

for($i=0; $i < 10; $i++) {     $return = (Alexa call here)      if(!strstr($return,'AuthFailure'))         break; } 

Adjust 10 to whatever number you wish. Better yet, use a constant define()‘ed elsewhere. This will run until the number of tries is exhausted or until the return value does not contain ‘AuthFailure’.
