Cannot read credentials from /.aws/credentials - PHP script call AWS-SDK

Just remove 'profile' => 'default', and you should work fine

$client = Route53Client::factory(array(
  'region' => 'us-east-1',
  'version' => 'latest',
  'credentials' => [
        'key' => $key,
        'secret' => $secret,
  ]
));

Running on AWS Centos 7, I tried everything (chmod/chown /root /home/user, env, bashrc, etc) to get the /.aws/credentials to work outside the apache /var/www directory. The SDK reported that it could not read the credentials file.

I looked at PHP to see if I could set/override the HOME variable and it still did not read the credentials file until I placed the .aws folder in the '/var/www' folder and set the HOME variable in my php file like so:

 <%php
 putenv('HOME=/var/www');

 //ZIP File SDK Install requires aws-autoloader
 require 'aws-autoloader.php'; //Your php code below
