问题
I wanted to setup a database connection from PHP to SQL server 2012.I have a wamp server(64 bit) set up on a windows machine(64 bit) with PHP 5.5.12 and on the same machine I have SQL server 2012 installed.
Extracted sqlsrv drivers from official_link
Copied the extracted drivers php_sqlsrv_55_ts.dll, extension = php_pdo_sqlsrv_55_ts.dll to php\ext folder, and then changed the php.ini file to include the extensions
extension = php_sqlsrv_55_ts.dll; extension = php_pdo_sqlsrv_55_ts.dll;
Now I tried
<?php
phpinfo();
?>
I see the following information without any SQL server information in it.
Don't seem to have configured SQL server connection successfully. Could some one please guide me on what I am missing here.
回答1:
Check the php error log (c:\wamp\logs\php_error.log). I had the same setup (64bit WAMP/PHP 5.5.12) and same missing sqlsrv reference in phpinfo and I got this error in my log:
PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_pdo_sqlsrv_55_ts.dll' - %1 is not a valid Win32 application. in Unknown on line 0
The solution was to install the 64bit version of the sqlsrv drivers. I found the unofficial 64bit drivers through http://robsphp.blogspot.nl/2012/06/unofficial-microsoft-sql-server-driver.html
Warning: In my testing I found these 64bit PHP_PDO_SQLSRV extension 10 times slower than when using PHP_PDO_ODBC.
回答2:
64 bit WAMP server was not able to connect using the drivers extension = php_sqlsrv_55_ts.dll; extension = php_pdo_sqlsrv_55_ts.dll;
So, I installed a 32 bit version of the WAMP server and it works fine now.

I am visiting this thread and i think this might help full for you and other with the same issue: How can I install pdo_sqlsrv on my windows 2008 Server 2008 R2?
The PDO Extension is not the same as the native driver Microsoft is offering. For PDO you must enable
extension=php_pdo_mssql.dll in your php.ini.
{Normally this file (php_pdo_mssql.dll) should be in your PHP extension-directory (C:...\php\ext). If it's not there you can download PHP from http://windows.php.net/download/ and just take the extension from a package there (take one that correspond with your PHP version of course)}.
Above is taken from PDO MSSQL Server - Driver not found read for more details. i have the same issue foe linux and i have saved all the pages thats why i am quoting for you help.
if all above didn't work for you then:
On the php.net it is listed that
On Windows, PDO_ODBC is built into the PHP core by default. It is linked against the Windows ODBC Driver Manager so that PHP can connect to any database cataloged as a System DSN, and is the recommended driver for connecting to Microsoft SQL Server databases. http://php.net/manual/en/ref.pdo-odbc.php
You can connect to mssql server using odbc drivers as i have never connect by my self from windows i use to do it through linux using freeTds, following pages might help you

- Connect PHP to MSSQL via PDO ODBC
- PHP to SQL Server without ODBC or MSSQL support
