How to connect to mssql using pdo through PHP and Linux?

Question

I'm trying to for a new PDO connection using the following code.

new PDO("mssql:driver=????;Server={$serverName};Database={$databaseName}", $username, $password, array(PDO::ATTR_PERSISTENT => false, PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));

I'm not sure what drivers to use? Or how to install them. I can connect perfectly fine using the mssql_connect function in PHP but I want to use the PDO library instead.

My php.ini settings for mssql are:

ssql

MSSQL Support   enabled
Active Persistent Links     0
Active Links    1
Library version     FreeTDS

Directive   Local Value Master Value
mssql.allow_persistent  On  On
mssql.batchsize 0   0
mssql.charset   no value    no value
mssql.compatability_mode    Off Off
mssql.connect_timeout   5   5
mssql.datetimeconvert   On  On
mssql.max_links Unlimited   Unlimited
mssql.max_persistent    Unlimited   Unlimited
mssql.max_procs Unlimited   Unlimited
mssql.min_error_severity    10  10
mssql.min_message_severity  10  10
mssql.secure_connection Off Off
mssql.textlimit Server default  Server default
mssql.textsize  Server default  Server default
mssql.timeout   60  60

Solution 1

The PDO mssql driver is no more, use sqlsrv (under php windows) or dblib (under php linux)

Solution 2

I am running Ubuntu 14.04. Trying to connect to MSSQL I got "Uncaught exception 'PDOException' with message 'could not find driver'". It seems that I was missing the dblib/sybase PHP extension.

I had to run:

sudo apt-get install php5-sybase freetds-common libsybdb5 \ 
&& sudo apache2ctl restart

Works fine now.

Solution 3

Try

$dbh = new PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw");

$hostname may need to be configured as either...
$hostname.':'.$port;

OR

$hostname.','.$port;

The error message that I get is Uncaught exception 'PDOException' with message 'could not find driver'

[Amir Fattahpoor]

using dblib still produces the missing drivers error. "Uncaught exception 'PDOException' with message 'could not find driver'". I find it strange that mssql_connect works fine yet I have to do something in order to get the PDO side working. I'm not very familiar with linux which means that I'm unsure of getting the drivers that I need sorted out?

You need to enable pdo_dblib.so in your php.ini and set up FreeTDS under Linux.

[shorif2000]

how do you enable pdo_dblib in configure? also I am using centos 5 32bit, how would I set it up?

[Dominick]

pdo_dblib no longer works with PHP 5.4+... I can't find a suitable solution to this problem.

@James Is the PHP Microsoft PDO_SQLSRV deprecated or is there no problems using it?

[James]

@Abdul Not that I'm aware of, why do you ask?

[Honinbo Shusaku]

@James I misunderstood your answer and thought that you can't use PDOs with mssql, but I'm guessing that's the PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw"); one that you can't use, and I need to import the MS drivers

[James]

Correct, "mssql" stopped being provided with PHP in 5.3 and "sqlsrv" and "dblib" are the current drivers (to my knowledge, it's been a while)

The php-sybase package solved the problem for me. I didn't need to install the others.
