I have been trying to connect remotely to oracle using pdo
I have enable pdo driver
extension=php_pdo_odbc.dll
But getting this error
"SQLSTATE[HY000]: OCIEnvNlsCreate: Check the character set is valid and that PHP has access to Oracle libraries and NLS data (ext\pdo_oci\oci_driver.c:614)"
Here is my code for connection
try {
$dbh = new PDO("oci:dbname='My server ip'/orcl;charset=UTF-8", "my user name", "my password");
}
catch (PDOException $e)
{ echo $e->getMessage(); }
I had the same errormessage after I installed multiple copies of ODAC/ODT because I didn't know what version I needed to have my Visual Studio projects (Windows Forms app and a ASP.NET website) connect to a Oracle database. While fixing this connection problem in the end, I broke my PHP/PDO website which also needed to connect to the same Oracle database. It gave me the same errormessage as in your question.
I removed all ODAC/ODT client installations and also the Oracle Server to be sure and then I reinstalled only the Oracle Server (in my case Oracle 11.2 Express 64bit) and it worked again. I could connect again from SQL Developer and also through PHP/PDO. After that I installed the correct ODAC/ODT (32bit(!) version because of my 32bit Visual Studio) and now also my Visual Studio Forms project AND ASP.NET website could connect to the Oracle server.

I'm using Microsoft Azure SQL for my database and I'm trying to connect it to my project on my localhost using XAMPP. When I try to connect to the database using the connect string they provided:
try {
$conn = new PDO("sqlsrv:server = tcp:app.database.windows.net,1433; Database = mydatabase", "{myusername}", "{your_password_here}");
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
}
catch (PDOException $e) {
print("Error connecting to SQL Server.");
die(print_r($e));
}
I keep getting this error:
Error connecting to SQL Server.PDOException Object ( [message:protected] => could not find driver
The error is longer but I think it's related to the driver mentioned at the end. I'm using a mac so any driver I need to install would need to be compatible with it. Thank you for the help in advance.
Azure SQL Database is built on the Microsoft SQL Server engine. So you might consider using pdo-dblib to connect to SQL Server using the PDO on a Mac. You can check out a Stack Overflow question about it here or refer to this setup documentation.
After the driver having been installed, Azure SQL won’t actually accept connection from your local yet. And you might get the following error:
Client with IP address '167.xxx.xxx.xxx' is not allowed to access the
server.
That’s because there is a firewall in the way by default. To enable access, go to the Azure portal, click on All Resources, select your SQL service, click on Firewall in the SETTING menu.
Your client address is conveniently included in the list, so you can just click on Add client IP followed by Save.
Well, when you run your code now, it should connect.
I have a Linux server running Wordpress 4.2 and I have 2 Azure DB, one is SQL Server and the other is CleanDB.
The Windows Server(s)
Windows 7 Pro/Windows Server 2012 R2 sp1
Visual Studio 2013
SQL Server 2012 sp1
PHP 5.4 WP 4.2
Linux Server
CentOS 6.0
WP 4.2
PHP 5.4.31
It runs on SQL server, visual studio, and my php script on my Windows server to the CleanDB and SQL Server run fine and when I run the connection string on the Linux server to the CleanDB.
It won't connect when I run the Linux server to the SQL server.
I only allowed the DB to allow 4 calls and it isn't pulling.
The IP ranges were added on the firewall.
I used the exact same string in all instances.
I found a few other related questions that some help:

Do you mean you couldn’t connect to SQL Azure from a Linux server while using sqlsrv drive? Please note, SqlSrv is a Windows driver, on Linux we can use PDO_DBLIB drive and PDO_ODBC (not recommend), more detailed info could be found at: http://php.net/manual/en/ref.pdo-dblib.php.
Code snippet via using PDO_DBLIB for your reference:
<?php
$dbHost = 'YourName.database.windows.net';
$dbUser = 'DBUserName';
$dbPass = 'DB Password';
$dbName = 'DB Name';
try {
$pdo = new PDO("dblib:host=$dbHost:1433;dbname=$dbName", $dbUser, $dbPass);
} catch (PDOException $e) {
echo "Failed to get DB handle: " . $e->getMessage() . "\n";
exit;
}
Code snippet via using PDO_ODBC for your reference:
$connection = odbc_connect("Driver={SQL Server};Server=$dbHost; Database=$dbName;", $dbUser, $dbPass);
$qry = "SELECT * FROM Clienti";
$result = odbc_exec($connection,$qry);
// Get Data From Result
while ($data[] = odbc_fetch_array($result));
// Free Result
odbc_free_result($result);
// Close Connection
odbc_close($conn);
// Show data
print_r($data);
AS to DB settings, please do not forget to manage allowed IP addresses on Azure portal, i.e. add your client IP address in Allowed IP Addresses section on Azure portal. https://msdn.microsoft.com/en-us/library/azure/ee621782.aspx#Troubleshooting

When I run apache (via xampp) as a standalone server not as a service (on Windows Server 2008)
with the following connection code everything works fine (username and password removed )
$server = "WMS";
$link = odbc_connect($server,'','');
if (!$link) {
die('Something went horribly wrong while connecting to MSSQL');
}else {echo('');}
If however I change apache to run as a service in Windows the connection breaks and I get the following error message
Warning: odbc_connect() [function.odbc-connect]: SQL error: [Microsoft][ODBC Driver Manager]
Data source name not found and no default driver specified, SQL state IM002 in SQLConnect in
C:\xampp\htdocs\Dev\well.php on line 30
Something went wrong while connecting to MSSQL
Please read documentation: http://uk.php.net/manual/en/function.odbc-connect.php
$server = "WMS"; suggests that you have ODBC alias/data source configured with that name. Error message clearly says that data source with such name (WMS) is not found. On Windows 7/Vista/XP/Server you can configure them at "Start -> Administrative Tools -> Data Sources (ODBC)" -- path can be different on older OS. In any case -- look for "Microsoft ODBC Data Source Administrator".
Instead of using alias, I would recommend (the way I always connect) to use full DSN name, e.g.
// Microsoft SQL Server using the SQL Native Client 10.0 ODBC Driver - allows connection to SQL 7, 2000, 2005 and 2008
$link = odbc_connect("Driver={SQL Server Native Client 10.0};Server=$server;Database=$database;", $user, $password);
In this case everything is part of the script and no external dependencies.
BTW -- instead of using ODBC Functions, I would recommend using PDO & driver specially for MS SQL Server: PDO_SQLSRV -- http://uk.php.net/manual/en/ref.pdo-sqlsrv.php (or Microsoft SQL Server Driver for PHP if you prefer old procedural style -- http://uk.php.net/manual/en/book.sqlsrv.php )
We are using MSSQL server 2008 on Win server 2008 R2 and have installed Apache (2.2.19) and PHP (5.2.17) separately. We have installd the MSSQL module for PHP and usingthe following connection string:
$myc = mssql_connect(Server, SiteDatabaseUsername, SiteDatabasePassword) or die('Can\'t connect to mssql Database Server: '.mssql_get_last_message($myc));
$db = mssql_select_db(SiteDatabaseName, $myc) or die('Can\'t find database: '.mssql_get_last_message($myc));
But it gives us this error:
Warning: mssql_connect() [function.mssql-connect]: Unable to connect to server: localhost\MSSQLSERVER in D:\Apache2.2\htdocs\adminarea\_core.php on line 89
Can't connect to mssql Database Server:
We have used the IP:PORT, localhost\MSSQLSERVER and COMPUTERNAME\MSSQLSERVER but don't seem to be getting anywhere, can anyone help please?
A few things come to mind:
1) Make sure you have the sqlsrv driver package from MS, and make sure you're loading it properly in php.ini (use phpinfo() to verify).
2) If this was a vanilla installation of SQL Server, its likely that only windows authentication is turned on. Open the SQL Enterprise Manager and make sure you have SQL Server Authentication enabled on your database.
3) Make sure that you have enabled network access to SQL Server. I'm not immediately certain whether the new MS drivers use named pipes to communicate with the server, or if they expect that the server will be accessed via the network.
These are the issues I routinely encounter when getting PHP speaking to a new MSSQL server.
I am trying to connect to SQL Server 2008 (not express) with PHP 5.2.9-2 on Windows XP sp2. I can connect to the remote SQL Server fine from SQL Server Management Studio from the same machine.
My first attempt was this:
$conn = new PDO("mssql:host={$host};dbname={$db}", $user, $pass);
Which gives this error:
PHP Fatal error:
Uncaught exception 'PDOException' with message
'SQLSTATE[0100] Unable to connect: SQL Server is unavailable or does not exist.
Access denied. (severity 9)'
Second attempt (found on experts-exchange)
$conn = new PDO("odbc:Driver={SQL Server Native Client 10.0};Server={$host};Database={$db};Uid={$user};Pwd={$pass}",
$user, $pass);
This works, but I can't use PDO::lastInsertId(), which I would like to be able to:
Driver does not support this function: driver does not support lastInsertId()
Do you have any suggestions? Any help would be greatly appreciated.
i'm pretty sure that pdo with the mssql data server type requires dblib to connect. do you have dblib installed on the machine? make sure you can find ntwdblib.dll somewhere in the path on your system. i know this doesn't jive with the error message you're getting, but i'm not sure i trust the error message.
I updated ntwdblib.dll as suggested here and it now works.
Unfortunately I still can't use PDO::lastInsertId() because apparently this driver does not support it either, so it wasn't really worth the hassle. I can however use the equivalent SELECT ##IDENTITY as Id.
That you cannot use SQL Server authentication because only Windows authentication is permitted.
Check if the server is running Mixed mode authentication.
Also check if this SO question helps you.
