Good afternoon, all the insure flew, nothing helps, all hope for you remains:

PHP 7, IIS 7.5 Windows Server 2008R2
When trying to connect to MSSQL, an error occurs:

PHP Fatal Error: Uncaught Error: Call to undefined Function SQLSRV_CONNECT () in C: \ inetpub \ path \ connect.php: 4
Stack Trace:
# 0 {Main}
 Thrown In C: \ Path \ Connect.php on Line 4

in php.ini directive extension = php_mssql.dll absent, the php.ini in this release is not replaced by PHP.ini-Development and php.ini-product

Script itself:

$ servername = "mssql02 \";
$ ConnectionInfo = Array ("Database" = & gt; "", "uid" = & gt; "," pwd "= & gt;" ");
$ Conn = SQLSRV_CONNECT ($ ServerName, $ ConnectionInfo);
if ($ Conn) {
   Echo "connection managed. & lt; br / & gt;";
} else {
   echo "connection failed, error:";
   DIE (Print_R (SQLSRV_ERRORS (), TRUE));
}

What is there no server name, user, password, etc. This is not an error, just removed specially

Pdo downloaded, threw into the EXT folder:

The php config added a line:
