Please help.

Answer 1

it work on command prompt something like:

php yourphpfilename.php

also you have an alternate way to pass the key file:

$credentialsFile = '[PATH_TO_JSON_KEY_FILE]';

# Instantiates a client
$bigquery = new BigQueryClient([
    'projectId' => $projectId,
        'keyFilePath' => $credentialsFile
]);

Hope it will help you.
