But when I try to access with the code:

<? Php

print_r (PDO::getAvailableDrivers ());

echo '<hr>';

$PDO = new PDO ('firebird:dbname=111.111.11.111/3050:test;charset=WIN1252', $user, $pass);

print_r($ PDO->getAttribute(PDO::ATTR_CONNECTION_STATUS));

?>

Returns:

Array ([0] => firebird [1] => mysql)

SQLSTATE [HY000] [335544472] Your user name and password are not defined. Ask your database administrator to set up a Firebird login.

I noticed that when I ran the command: apt-get install php7.0-pdo-firebird

He installed /usr/lib/firebird/2.5

What am I doing wrong?

Doing this remotely with ibexpert I can connect without error.
