php dblib, Error: SQLSTATE[HY000] Unknown host machine name (severity 2) - php

Question

I am using mac computer OSX 10.9. Freetds and unixODBC are already installed on my computer and added as extension to php , trying to connect to a remote MSSQL server. Below is my connection testing:
<?php
$dbh = new PDO('dblib:host=Hostname ;dbname=Dbname', 'user', 'pw');
if (!$dbh) {
die('Something went wrong while connecting to MSSQL');
}
?>
The error logs file show :
[error] [client 127.0.0.1] PHP Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] Unknown host machine name (severity 2)
What could be the problem ? It seems that my freetds and unixODBC are working fine if I use terminal to connect to the same database as below:
$ isql Hostname user pw
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+
SQL>
and
$ tsql -S Hostname -U user
Password:
locale is "en_US.UTF-8"
locale charset is "UTF-8"
using default charset "UTF-8"
1>
here is my freetds.conf
[global]
# TDS protocol version
tds version = 8.0
[Hostname]
host = IP
port = 1433
tds version = 8.0
client charset = UTF-8 ##needed on MAC OS X
dump file = /tmp/freetds.log
and my odbc.ini
[Hostname]
#Driver=/usr/local/lib/libtdsodbc.so
Driver = /usr/local/Cellar/freetds/0.91_2/lib/libtdsodbc.so
Trace=No
Server=IP
Port=1433
TDS_Version=8.0
client charset = UTF-8
my phpinfo() shows that the extension has been added, there is dblib in PDO section and pdo_dblib section have driver Flavour enabled freetds.
So what is the problem? Any idea of what I should do ?
Any assistance will be highly appreciated.
here is my odbcinst.ini:
[freetdS]
Description = v0.63 with protocol v8.0
Driver = /usr/local/Cellar/freetds/0.91_2/lib/libtdsodbc.so

Answer 1

I actually solved this question by deleting both mssql.so, pdo_dblib.so in php extension folder, re-download php5.4 , phpize and build both the .so files again and put it back. Then it works.
It seems that the olde pdo_dblib.so file I made pointed to a different freetds.conf somewhere else.

Since it is not possible to debug this by proxy without real files information and you've opted to protect ip addresses and hostnames with dummy text. I am going with the PHP code. The hostname should be a FQDN or an ip address. Not the place holder text from the ini files.
<?php
$dbh = new PDO('dblib:host=[ ip address || example.com || localhost] ;dbname=Dbname', 'user', 'pw');
if (!$dbh)
{
die('Something went wrong while connecting to MSSQL');
}
?>
