Fatal error Call to undefined function sqlsrv connect

Question

Even though I have read a lot of posts on the same topic, I am still unable to find an answer, so I ask. In my php script, I'm trying to connect to SQL. What is my connection string?

/* Specify the server and connection string attributes. */
$serverName = "xxx-PC\SQLExpress";
$connectionOptions = array("Database"=>"Salesforce");
$conn = sqlsrv_connect($serverName, $connectionOptions);
if($conn === false)
{
      die(print_r(sqlsrv_errors(), true));
}

I have installed and included the following in my php.ini file located under the wamp folder: C:\wamp\bin\php\php5.4.16:

extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll

My wampserver is running fine and so are the wampapache and wampsqld services. I am able to execute php.exe successfully. However I am unable to make the connection to SQL Server 2008 R2 where my database is located. Please help!

EDIT 1: The wamp server is running the wampmysql service while I am trying to connect to SQL Server 2008 R2. Could this be the reason? Should I be using MySQL instead of SQL? Any pointers?

EDIT 2: I do not see sqlsrv section at all when I run phpinfo() though I have added extension=php_sqlsrv_54_ts.dll in the php.ini file located in the bin folder of the wamp server.

Can someone please help me with this?

Answer 1

This helped me get to my answer. There are two php.ini files located, in my case, for wamp. One is under the php folder and the other one is in the C:\wamp\bin\apache\Apachex.x.x\bin folder. When connecting to SQL through sqlsrv_connect function, we are referring to the php.ini file in the apache folder. Add the following (as per your version) to this file:

extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll

I hope this helps you.
