How to access Postgres .pgpass file from php?

I have my php files in the web root, and the Postgres 10 logon

After research, I found the .pgpass file.  That looks like the ideal
solution, but after even more research, I haven't found how to use that
file from a php logon script.

Here is the section from my php script:

$dsn = vsprintf('pgsql:host=%s;port=%s;dbname=%s;user=%s;password=%s', [
    'host' => '000.00.00.00',
    'port' => '5432',
    'dbname' => '[dbname]',
    'user' => '[username]',
    'password' => '[password]',
]);

Currently I store the real dbname, user and password in the php.  My
questions are:

1. How can I access it from the .pgpass file instead?

I think what you are looking for is the connection service file:

https://www.postgresql.org/docs/11/libpq-pgservice.html

2. Where is .phpass loccated in Apache2 Ubuntu 18.04?

Information on where .pgpass can be:

Thanks for any help with this.

We use pg_service.conf to hold the access credentials.
It's just pg_connect("service=sandbox") for example, where 'sandbox' is
the tag for the database you wish to access.
Using Debian it is kept in the /etc/php/7.3/apache2 path, where 7.3
represents the php version. It needs to be owned by the Apache user
which defaults to 'www-data'. Permissions are 0600.
