I have a SQL server 2008 R2 (running on Windows server 2008 64bit), which I'm trying to connect from PHP
My PHP server configuration:
CentOS 6.6
PHP 5.5.24 (compiled --with-mssql=/usr/local/freetds --with-pdo-dblib=/usr/local/freetds)
Apache 2.4.12
SELinux is disabled (according to this solution: PDO DBLIB accessing SQL Server 2008 and 2012 )
I wrote the following PHP code to connect to the SQL server:
try {
require "classes/mypdo.class.php";
$pdo = new MyPDO('dblib:dbname=myDB;host=myServer', 'myUser', 'myPassword');
$pdo->debug = true;
} catch (PDOException $e) {
die("Connection failed: {$e->getMessage()}");
}
The connection failed with an error:
Connection failed: SQLSTATE[HY000] Unknown host machine name (severity 2)
I tried other DSN syntaxes like:
$pdo = new MyPDO('dblib:host=192.168.0.10', 'myUser', 'myPassword');
$pdo = new MyPDO('dblib:host=192.168.0.10:1433', 'myUser', 'myPassword');
$pdo = new MyPDO('dblib:host=myServer', 'myUser', 'myPassword');
and many other variations... When I use an IP address instead of DSN the error is:
Connection failed: SQLSTATE[HY000] Unable to connect: Adaptive Server is unavailable or does not exist (severity 9)
/etc/freetds.conf
[global]
tds version = 7.1
dump file = /tmp/freetds.log
timeout = 10
connect timeout = 10
text size = 64512
client charset = UTF-8
[myServer]
host = 192.168.0.10
port = 1433
tds version = 7.1
I suspect that PHP ignoring freetds.conf (can't confirm it).
When I use tsql the connection is working.
tsql -S myServer -U MyUser -P MyPassword
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"

What is the reason that PHP refusing to connect to the SQL server?
There are sometimes problems with an setting inside php.ini
Please try to change:
mssql.secure_connection = Off
to
mssql.secure_connection = On
