I have got FreeTDS, unixODBC and ODBC enabled on PHP. It all seems to work great. I could connect via iSQL command line.
For some reason PHP is not able to work when accessed via HTTP.
For example.
via command line if I run php index.php (where index.php connects via ODBC) it works well.
but the same code when accessed via HTTP, returns
Warning: odbc_connect(): SQL error: [unixODBC][Driver Manager]Data source name not found, and no default driver specified, SQL state IM002 in SQLConnect
Could this be a case of some permission
Thanks in advance
Here is the connection code
$connect = odbc_connect("DSNNAME", "USERNAME", "PASSWORD") or die('e');
I have changed the credentials. But the code works fine when I run it via PHP command through SSH via Terminal. But when I run it through HTTP it does not.
Also on SSH I am NOT running it via root user. I am using ec2 AWS - and ran SSH via ec2-user (which is the default)
I feel 'apache' user does not have permission to something which I am unaware of.
You can add the DSN from the PHP source code like this
$dsn = "Driver=FreeTDS;Server=192.168.1.17;Port=1433;Database=mydb;TDS_Version=7.2;";
$Connection = odbc_connect($dsn,$user,$pass);
2021 - BACK TO THE FUTURE:
I know that this post is old, but my reply can point a desperate soul in the right direction:
You are using odbc and the command "isql" works just fine
You are using FreeTDS and the command "tsql" works just fine
Trouble is running the php scripts that have calls to odbc via FreeTDS -> keeps giving errors

it's about more than one full day that i started sqlanywhere and i'm so interested to use it,
i worked before with sqlsrv for ms sql server and connection via php ,
but i have problem for connecting php to sqlanywhere
here is the warning message when i try to run test.php
Installation successful Using php-5.6.0_sqlanywhere.dll
Warning: sasql_connect(): SQLAnywhere: [-100] Database server not found in C:\xampp\htdocs\test.php on line 44
Connection failed
$conn = sasql_connect( "UID=DBA;PWD=sql" );
if( $conn ) {
echo "Connected successfully\n";
sasql_disconnect( $conn );
} else {
echo "Connection failed\n";
}
I'm using xampp server php 5.6 and sqlanywhere 17 developer edition.
already i downloaded the php extension and copied on ext and also added the line in php.ini (extension=php-5.6.0_sqlanywhere.dll)
demo database i ran it with cmd : dbeng17 "%SQLANYSAMP17%\demo.db".
via cmd i tried this also :
C:>dbping -d -c "uid=dba;
SQL Anywhere Server Ping U
Connected to SQL Anywhere
Ping database successful.
but when i try via php it says: Warning: sasql_connect(): SQLAnywhere: [-100] Database server not found in C:\xampp\htdocs\test.php on line 44
Connection failed
please someone tell me what is the problem ?
thank you very much.
Your PHP installation may have multiple files similar to php.ini. Make sure you are modifying the php.ini file listed in phpinfo().
- A web server such as Apache, IIS, or any web server that supports
PHP.
- PHP installed on the same computer as the web server.
- SQL Anywhere installed on the same computer as the web server.
- The client software can be used as well. SQL Anywhere PHP extension

It solved for me when I installed and used it on another system , I don't know I tried first on a system that MSSQL server was install and I couldn't run it and tried on another system that mssql server was not installed and solved :)
sorry for being late to answer and thank you very much for those who took time to help me.
I trying to connect to a MSSQL Server with PHP. For that I am using the following script:
function mssqli_connect($server,$username,$password,$database){
$connectionInfo = array("Database"=>$database, "UID"=>$username, "PWD"=>$password);
return sqlsrv_connect($server,$connectionInfo);
}
I am running PHP 7.0.7 on a Windows Server with the IIS 7.5. Unfortunately it doesn't work and I have no idea why.
What I've already tried
I dumped the function, but it only returns bool(false), which is not very helpful. I also tried to ping the server via cmd. This has succeeded. The credentials are also correct.
The extension php_sqlsrv_7_nts.dll is also requested in the php.ini, so it doesn't give me an error, that the function wasn't found.
Do I miss something, which is required?
I searched again. Now what I found is an other driver software, which is a msi executable file, which installs the odbc driver on the machine.
https://www.microsoft.com/de-ch/download/details.aspx?id=36434
I installed that software and now it works without any problems.
Thanks for all your comments.
PHP Version: 7.0.14
Working on Windows Server 2012
Database files are in D: drive
Website/Application is assigned to the Application pool correctly
Assigned Application pool has the permissions to D: drive
Trying to connect and fetch information from ToppSpeed Database.
Created DSN correctly using Topspeed ODBC Driver.
I have created a sample script to verify if it is working or not.
odbctest.php
$conn=odbc_connect("DSN_NAME",'',''); //Make a coonection to DSN
if (!$conn){
exit("Connection Failed: " . $conn);
}
$sql="SELECT * FROM ExampleTableName"; // Query String
$rs=odbc_exec($conn,$sql); //Execute Query <--- Error Line
if (!$rs) {
exit("Error in SQL");
}
while (odbc_fetch_row($rs)){
var_dump(odbc_result($rs,1));
}
odbc_close($conn);
Error:
PHP Warning: odbc_exec(): SQL error: [SoftVelocity Inc.][TopSpeed ODBC Driver][ISAM]ISAM Table Not Found, SQL state S0000 in SQLExecDirect in C:\inetpub\wwwroot\projectFolder\odbctest.php on line 9
Working: When I run same file on PHP inbuilt server using command > php -S localhost:8002
and run file in a browser at http://localhost:8002/odbctest.php Everything works fine.
Working: When I run file in command line > php odbctest.php It works fine I got data from the table.
Not Working: I have added the website in IIS Manager, bind the website(physical path is C:\inetpub\wwwroot\projectFolder ) with the local IP
When I open that odbctest.php in a browser with local IP I am getting Table NOT Found error.
Same Script, Only difference is it is running on Command Line and not on IIS server, It is running on PHP inbuilt server and not working on IIS.
other Technical Difference is
I have put one PHP file to see PHP information on both servers.
Here is the only difference I found in that.
Working On PHP inbuilt server: In PHP info Server API is: Built-in HTTP server
Not working on IIS Server: in PHP info Server API is: CGI/FastCGI
there is not issue in DSN string because when I change the DSN string with unknown it identifies that there is something wrong in DSN string.
I think there might be some permission issue when trying to access data from IIS server (PHP runs on CGI/FastCGI).
I am wondering if there is permission issue why the error says table not found!!
I don't find any good documentation for TopSpeed Database connection error as this database is not widely used.
Any suggestion or idea? Please advise. Thank you in advance.
The database SQL error was not stating anything about permission,
so I created a simple another PHP script to append data to TEXT file.
I ran that PHP script with two test cases on the IIS server
Test Case 1: Write in a text file which resides in the project directory(same server)
And PHP script executes correctly and it wrote data to text file.
Test Case 2: I change the text file path with the file D:\some_directory\logfile.txt (Resides on D drive)
And when I ran it again script again I got the following error:
Warning: file_put_contents(D:\some_directory\logfile.txt):
failed to open stream: Permission denied in
C:\inetpub\wwwroot\project-directory\write.php on line 12
It confirms there is some problem with the Permissions
App pool assigned to the Website in IIS manager already had the permission to D: Driver. So it was not the problem.
In more research, I found that
we need to identify the USER first that we need to provide the permissions and the user is the value of "Anonymous user identity"
https://stackoverflow.com/a/32033941/5236174
https://www.iis.net/configreference/system.webserver/security/authentication/anonymousauthentication?showTreeNavigation=true
I saw that the value of Anonymous user identity was not the Application Pool!!
I changed that to the Application pool identity.
So now the website/application's anonymous user identity become the App pool and that has correct permissions.
Afthesethis changes, everything works perfectly fine as there is no permission issue.
In PHP scripts, it looks like this is how you connect to an odbc database:
$connection = odbc_connect("Driver={SQL Server Native Client 10.0};Server=$server;Database=$database;", $user, $password);
The problem I'm having is that I don't know what to use for "Driver=". What I put in there is what was provided for another script I saw. In my script, all I do is try to connect using this line, but I get the following error:
Warning: odbc_connect(): SQL error: [unixODBC][Driver Manager]Data source name not found, and no default driver specified, SQL state IM002 in SQLConnect in /srv/www/htdocs/site/test.php on line 8
From what I can tell, it looks like the driver I specified is incorrect. The database I am trying to connect to is an MSSQL database, and I only plan to query for information from it. Is there a way to list the database drivers I have available on my system? I've never had to install/configure any drivers like this before (I've never done anything like this; all php work I've done in the past has been with MySQL). Also, I don't want to compile other software onto my system (if possible); I would prefer to install all packages from repos.
You should have a file called odbcinst.ini (probably in /etc or /usr/local/etc but you can locate it with the command odbcinst -j). This file defines your ODBC drivers. Each driver is named within the [] in each section.
You might find Linux ODBC useful as it contains a thorough explanation of unixODBC, how it works and how to define data sources.
The question was how to find the list of ODBC drivers available. In the command line run:
odbcinst -q -d
This will list the drivers if you don't know already.
I am trying to connect to a Microsoft Access Database using PHP PDO, but got this error message:
SQLSTATE[IM002] SQLDriverConnect: 0 [Microsoft][ODBC Driver
Manager]Data source name not found, and no default driver specified
The error happens at this line:
$dbh = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb,*.accdb)};Dbq=C:\\wamp\\www\\phprestsql\\UTILITY.accdb");
I do not have an user name setup for the database, I also tried
$dbh = new PDO("odbc:Driver={Microsoft Access Driver (*.mdb,*.accdb)};Dbq=C:\\wamp\\www\\phprestsql\\UTILITY.accdb;User=Admin");
and the problem still remains
What could be the problem? I checked the path for the Access Database file and it is correct.
I am using the WAMP for the PHP.
The system is Windows 7 Home Premium. Do I need to install some ODBC driver?
Edit:
I downloaded the ACE according to HansUp's suggestion, but still has the same problem.
I have also tried to convert my file to .mdb, but still has the same problem. In the PHP code I verified the ,mdb file does exist. So it must be some kind of environment issue.
Update
Forgot to mention that I was running Virtual Box on Mac. Perhaps that was the problem.
Got really frustrated, then moved on to an old Windows Vista 32 bit machine and setup the environment using all 32 bit tools. It worked in the first run.
Thanks
