PHP fatal error: Uncaught exception 'Exception' with message

Question

I have a PHP script that connects to an api and posts information to their systems, but when its trying to connect it throws a fatal error:

Fatal error: Unca         


        

Answer 1

or You can change the headers:

$optional_headers = 'Content-Type: application/json')

Answer 2

apitestserver.co.uk doesn't respond to ping and the url is inaccessable. The API-server doesn't seem to be up.

Answer 3

First error message suggests problems with apitestserver - it returns error code 500, which states for "Internal server error".

Second one informs that PHP can't resolve host name into IP address - I'd look into DNS configuration and/or hosts file.

Apparently 'fopen' function does not return proper stream. There can be many possibilities when that happens, but according to PHP manual, fopen function on fail should present E_WARNING message with proper commentary. It is possible that you have errors of that class silenced - call error_reporting(E_ALL) at the beginning of your script and look for some relevant error messages.

Answer 4

I just tested the URL in my browser and got a connection error.

Maybe the problem is with their server (or you have the wrong URL)?

Edit:

Looks like ther server is throwing a 500 error - maybe because the data you're posting is invalid.

You could use a packet sniffer and check the exact data you're sending to the server (or use cURL as suggested by @acrosman)

Answer 5

I would suggest using curl instead of fopen(). curl is both more flexible, and more secure. Many servers disable allow_url_fopen, curl also fails more gracefully when there are problems on the remote server.
