hi @leepolanco

Did you follow every step in our instruction documentation?

What's the output when you ran odbcinst -q -d -n 'ODBC Driver 13 for SQL Server'

FYI, this is the FAQ which might help.

[leepolanco]

Thank you Yitam for getting back to me.
Somewhat i did follow steps, php/apache were compiled locally due to network restriction on our site.
sqlsrv items, the setup was followed as described (phpsize, etc.. as described)

but still looking for hints.
what's funny.. testscript.php (which connect SQL DB) works fine from command line.
just not working on browser.

Output of: odbcinst -q -d -n 'ODBC Driver 13 for SQL Server'

Hi @leepolanco, something is wrong, but please try the followings:
(1) cat /etc/odbcinst.ini
(2) ls -l opt/microsoft/msodbcsql/lib64/ (you should see libmsodbcsql-13.1.so.9.2)
(3) dltest /opt/microsoft/msodbcsql/lib64/libmsodbcsql-13.1.so.9.2 SQLGetInstalledDrivers

[yitam]

Hi @leepolanco, depending on some environment variables, where unixODBC finds odbcinst.ini can be different.

Please try doing an strace like this

strace [apache process] | grep odbcinst.ini

FYI about strace
strace: must have PROG [ARGS] or -p PID
Try 'strace -h' for more information.

[leepolanco]

thank you again.
but still searching.
keep you posted if anything

[yitam]

Hi @leepolanco, you might want to try this in a clean environment. Just a suggestion, of course.

So what's the output of strace [apache process] | grep odbcinst.ini?

[yitam]

@leepolanco just thought it's worth trying to run phpinfo() in your browser.

Do you have more than one php version installed? Is there more than one php.ini in your env, for example? This link might be useful.

[leepolanco]

thank you!

fyi:
Only one php.ini and phpinfo() runs fine on browser..

This is test SQLconnection code runs well command line but on not browser!
test code:

command line:
$date; php mytest2.php ;date
Tue Jun 26 23:08:31 EDT 2018
Connection established.
Tue Jun 26 23:08:31 EDT 2018

Hi @leepolanco, I have not been able to reproduce this. I don't have freeTDS in my env however. Can you try this in another setting without freeTDS? Meanwhile I will do some investigation.

[yitam]

Hi @leepolanco, even with freeTDS installed I have no problem connecting using browser (Apache). Yet, I didn't really configure freeTDS or specify any DSN.

That being said, you don't need freeTDS to connect to MS SQL Server. The MS ODBC driver is what the php drivers need to connect to SQL Server.

This is another useful reference you might find useful.

[yitam]

hi @leepolanco , any update? Another user (see issue #805) has experienced a similar issue and managed to find a solution. Please take a look and see if it helps.

[leepolanco]

Thank you for following up.
fyi - we are trying to upgrade from RHEL 7.3 to 7.4.
i think, this might be related to openssl (1.0.1) version we have installed on RHEL 7.3.
on RHEL 7.4, we will have openssl 1.0.2
keep you posted.

[leepolanco]

Updates:

• After upgrade to RHEL7.4 and openssl1.0.2 libs installed

• the msodbcsql17-17.2.0.1-1.x86_64.rpm, mssql-tools-17.2.0.1-1.x86_64.rpm drivers installed.

• compiled pdo_sqlsvr.so , sqlsvr.so load.

works fine

thank you!!!
