        port = 26401
        tds version = 5.0

===
test script
php -r "new PDO('dblib:host=7.140.28.88:26401;dbname=dwhdb','dcbo','dcbo');"



Expected result:
----------------

Is it possible to use a different TDS version? There's a comment in the source suggesting that 5.0 isn't supported:
https://github.com/php/php-src/blob/PHP-7.1.4/ext/pdo_dblib/dblib_driver.c#L312

If that doesn't work, it would help to know if this was a regression between PHP versions. I don't have a local instance of Sybase, so this may be difficult to help debug, but that might point the way.
 [2017-04-25 00:56 UTC] fuzzywy at 163 dot com 
I've been aware of the issue so i checked the source code in 5.5.15
(in which version my program works well).

https://github.com/php/php-src/blob/PHP-5.5.15/ext/pdo_dblib/dblib_driver.c

It's same as the code in 7.1.4 that there's a comment in version 5.0。

And i also test it in 7.0.x, change the global tds version in my freetds.conf to 4.2, both can not work。
 [2017-04-28 17:29 UTC] adambaratz@php.net 
Are you familiar with TDSDUMP environment variable?
http://www.freetds.org/userguide/logging.htm

Try doing this for both PHP versions:
TDSDUMP="freetds.log" php -r "new PDO('dblib:host=7.140.28.88:26401;dbname=dwhdb','dcbo','dcbo');"

If you share both log files, I might be able to help debug.

Sorry for the delay in responding. I didn't get an email with your latest comment for some reason.

If you look in the trace, it says there's a syntax error coming from the use statement. I believe this results from the dbuse() call in pdo_dblib_handle_factory, but I don't think I don't think this issue could be coming from pdo_dblib. If you compare master to the 5.5.15 branch, you'll see that this function has changed very little since then.

My guess would've been that this is an issue with FreeTDS. I'm not sure what to make of the fact that you can otherwise connect to this server with FreeTDS. If you're able to get the log from that session, that might reveal what's going on.

It's hard to say what's going on here. Very little has changed in pdo_dblib between 5.5 and 7.1. That said, there are differences in the logs.

This happens in 5.5:
09:53:54.630614 14500 (net.c:741):Sending packet
0000 0f 01 00 21 00 00 00 00-21 14 00 00 00 00 73 65 |...!.... !.....se|
0010 74 20 74 65 78 74 73 69-7a 65 20 36 34 35 31 32 |t textsi ze 64512|
0020 20                     -                        | |


This happens in 7.1:
net.c:741:Sending packet
0000 0f 01 00 2c 00 00 00 00-21 1f 00 00 00 00 73 65 |...,.... !.....se|
0010 74 20 74 65 78 74 73 69-7a 65 20 36 34 35 31 32 |t textsi ze 64512|
0020 20 75 73 65 20 5b 64 77-68 64 62 5d             | use [dw hdb]|

After that packet is the error that results in the PDO exception. I see two differences: two ! (instead of , and !), invoking USE right after the SET. In 5.5, USE is invoked earlier.

My guess is that there was some build difference that's causing the connection to be made differently. You could double-check your PHP build settings and see if anything stands out. Another thing you could try would be upgrading to FreeTDS 1.0. Newer versions have a slightly different way of selecting the database:
https://github.com/php/php-src/blob/PHP-7.1.4/ext/pdo_dblib/dblib_driver.c#L415

Maybe that would cause this issue to go away.

I'm not sure what other help I can offer. I don't have access to a Sybase server, so it's difficult to do any testing of my own. Sorry you're having this problem with pdo_dblib. I realize this must be a frustrating thing to have to deal with on your end.

Closing as this doesn't appear to be related to pdo_dblib.

I finally resolved the case by replace dbname to dbName in pdo_dblib dsn.

Howerver,the manual's still dbname.
