Fatal error: Call to undefined function mssql_query()


Recommended Posts

Hi, I am new in PHP. I have tried to connect MSSQL 2005 through php.

I am using xampp 1.8.0 

But once run, error msg is "Fatal error: Call to undefined function mssql_query()".

I have copied  "php_mssql.dll" in PHP folder  and enable in PHP.ini as "extension=php_mssql.dll "

and also tried copied in PHP/ext folder also (all above got from forum PHP Freaks Previous topics)


But nothing happened. Same error appear. Can anybody help?


Pls Help me.


Below is code.  I am running xampp in my local mechine with Win 7 pro


It is config.php



$myServer = "sils-pc";
$myUser = "sa";
$myPass = "544Hjy%2*2";
$myDB = "tempDB"; 
$conn = new COM ("ADODB.Connection") or die("Cannot start ADO");
$connStr = "PROVIDER=SQLOLEDB;SERVER=".$myServer.";UID=".$myUser.";PWD=".$myPass.";DATABASE=".$myDB; 




include 'config.php';
$query = "SELECT * FROM vw_Film_Certs_Display order by id";
//$query = mssql_query('SELECT * FROM
$result = mssql_query($query);
$numRows = mssql_num_rows($result); 
echo "<h1>" . $numRows . " Row" . ($numRows == 1 ? "" : "s") . " Returned </h1>"; 
while($row = mssql_fetch_array($result))
  echo "<li>" . $row["id"] . $row["name"] . $row["year"] . "</li>";

Try this


$result = mssql_query($query, $conn); 


in the place of:


$result = mssql_query($query);


As you have to specify which connection to use. A page may have multiple db connections

putting the [optional] connection parameter into the query statement won't fix the fact that the extension isn't installed.


to the OP, if you should happen to visit this thread, starting in php5.3 the mssql extension is no longer available and you must switch your code to use the SQLSRV extension. wherever you found the php_mssql.dll file at, it is likely not complied for the same version of php you are using and isn't loading due to errors (check the web server error log.)


this regurgitated information can be found in the mssql documentation at php.net
