mssql not loaded

Good day!

I try a lot of configuration to work my connection from php to mssql but still I cannot connect. And I got a code to check if the mssql was loaded.

Here is the code:

<?php

if (function_exists('mssql_connect')){

echo "Okay, fn is there<br>------------------<br>";

} else {

echo "Hmmm .. fn is not even there<br>------------------<br>";

}



if(extension_loaded("mssql")) {

echo "MSSQL is Loaded<br>";

}

else {

echo "MSSQL not loaded<br>";

} 



if(extension_loaded("msql")) {

echo "MSQL is Loaded<br>";

}

else {

echo "MSQL not loaded<br>";

} 

echo '<br><br>';



$ext = get_loaded_extensions();

if(in_array('mssql', $ext))

echo 'u have mssql installed<br><br>';

else

echo 'u do NOT have mssql installed<br><br>';



phpinfo();

?>

And when I run this code the result is:

Hmmm….fn is not even there
----------------------
MSSQL not loaded
MSQL not loaded
You do NOT have mssql installed
And the list of phpinfo() appear.

Actually I run this code when my php version is php 5.2.4 and now I try it to php 5.1.4 and the result is still the same.

Web server is IIS 6.0
OS is Windows Server 2003 R2 Standard Edition
PHP version is php 5.1.4
MS SQL Server 2005 Express Edition –Windows Authentication.

I need to solved this problem because my connection in mssql is not working because call to undefined the function mssql_connect().

I hope somebody can help me. Almost three weeks I configure this connection and still I cannot connect.

Any help is highly appreciated.
Thank you.
