file_get_contents php and json_decode error

Question

I am facing a weird problem with file_get_contents and decoding to json the result. I have to tell you that this code was fully functional in other server.

Answer 1

The json is simply invalid.

In front of the first opening curly braces there is the following content (hex encoded) ef bb bf ef bb bf

It is the utf8 bom.

There is a question related to deal with exactly that, so I will not cover it here. Read up here:

How to remove %EF%BB%BF in a PHP string

and another one dealing specifically with json here:

Convert UTF-8 with BOM to UTF-8 with no BOM in Python

Answer 2

Try to give JSON URL in the http://jsonlint.com/ and than copy the response and paste it in a file with BOM disabled you will notice that there is a strange small line in the beginning before the opening { bracket which is causing the issues
