for my final project I am trying to query a barcode database through via their API.

When I hardcode the barcode and api key, everything works as expected but when I am using variables, file_get_contents() keeps returning false.

works

$response = @file_get_contents("https://api.outpan.com/v2/products/039800027047?apikey=[APIKEY]");

Doesn't work

$apikey = // APIKEY; 
$barcode = 039800027047;
$response = @file_get_contents("https://api.outpan.com/v2/products/".$barcode."?apikey=".$apikey);

Anyone wanting to take a gander at what I'm doing wrong?

ps: the API documentation can be found at https://www.outpan.com/developers.php


Edit:

maybe I am missing something?

$contents = file_get_contents("https://api.outpan.com/v2/products/{$barcode}?apikey={$apikey}");

still doesn't work but this does:

$contents = file_get_contents("https://api.outpan.com/v2/products/{$barcode}?apikey=/* hardcoded APIKEY */");

The error changed though, now it displays file_get_contents(https://api.outpan.com/v2/products/039800027047?apikey=00000000000): failed to open stream: php_network_getaddresses: getaddrinfo failed: No address associated with hostname in /home/jharvard/vhosts/panapp/includes/functions.php on line 60

(apikey zeroed out)

ps: I double checked whether I'm passing in a wrong apikey but everything should be exactly the same (it's been copy pasted)

You're missing closing quotation marks in your url.

  • I changed the code but am still getting a (different) error. I added this in the original post – Vincent Feb 16 '16 at 9:06

After looking for a long while, I finally got it... it's a badly configured api (ie on outpans side) - I think they were doing something on their side (I could view their whole api directory at some time yesterday).

Anyway, got everything working and notified the outpan team!
