''So if you put your settings into the global my.cnf (probably in /etc or
/usr/local/mysql*) is there a difference?''
No. I get the same errors.
To be honest, NOT implementing MYSQLI_READ_DEFAULT_FILE is a huge bug for us. Our processor cluster
uses arbitrary connection values on a per-request basis, connecting to our database cluster of over
100 database instances. We don't like having to needlessly read sensitive connection data into
user memory, and consider this lack of support to be one of our greatest security concerns. I am
under the impression that PHP/Zend considers itself to be suitable for enterprise environments.
Also, note the assertion of implementation found at http://php.net/manual/en/mysqli.options.php
It's a bug.

Might as well reopen this since we're talking about it.

I was looking at the source code for mysqli and mysqlnd earlier and it seemed like the
MYSQLI_READ_DEFAULT_FILE/GROUP settings were explicitly not implemented. That's why I said to
repro without using those.
So if you put your settings into the global my.cnf (probably in /etc or /usr/local/mysql*) is there
a difference?

All our databases are remote. Using DNS is obviously correct, but it makes no difference if we use
either an IPv4 or DNS for the host. Localhost is a red herring here.
"mysql --defaults-extra-file=my.cnf" works fine from commandline, and fails within php.
Now tested in both 5.6 and 7.
Compare the two following code fragments.
<?php
//This code works. It's a nasty workaround.
mb_internal_encoding('UTF-8');
$mycnf="/Users/ben/my.cnf";
$sqls = parse_ini_file($mycnf);
$sql = mysqli_init();
mysqli_real_connect($sql,$sqls['host'],$sqls['user'],$sqls['password'],$sqls['database']);
if ($rs = $sql->query("select TABLE_NAME from information_schema.columns group by
TABLE_NAME")) {
print $rs->num_rows . "\n";
$rs->close();
};
//
<?php
//This code fails.
mb_internal_encoding('UTF-8');
$mycnf="/Users/ben/my.cnf";
$sql = mysqli_init();
mysqli_options($sql,MYSQLI_READ_DEFAULT_FILE,$mycnf);
mysqli_real_connect($sql);
if ($rs = $sql->query("select TABLE_NAME from information_schema.columns group by
TABLE_NAME")) {
print $rs->num_rows . "\n";
$rs->close();
};
In my opinion, PHP shouldn't even need read access to the file - as it should pass over the
information to the mysqlclient library, which should need read access to the file.

Do you have host=localhost? If so then the error message is probably referring to a missing socket
file (which it always tries to use with host=localhost). Try with host=127.0.0.1 to force a TCP
connection.
