Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php RTFM: "In case a second call is made to mssql_connect() with the same arguments, no new link will be established, but instead, the link identifier of the already opened link will be returned."

The last STEP in the following sequence with the CONDITIONS FAILED STEPS: 1. establish connection #1 2. establish connection #2 and close it 2a. repeat 2 (connect and close this connection) 3. execute a query under connection #1 - FAILED CONDITIONS: 1. all the connections use the same username and password, 2. step #2 is performed inside a function Step 3 failed with '<RESOURCE_ID> is not a valid MS SQL-Link resource' message. It looks like the conn.#1 is closed. Some modifications of this algorithm WORK without any error. All above WORKS if do not repeat connection #2 (remove step 2a). Also all above (1,2,2a,3) WORKS if connection #2 is established for a different user. The code below contains 'step2()' function which just opens and closes the db connection. So the variables which handle resources for connections #1 & #2 belong to separate variable scopes. If I remove this function and insert its code instead of its call (the common variable scope is used) then ALL WORKS! Reproduce code: --------------- // // initialize variables // $servername = 'servername'; $dbname = 'dbname'; $user = 'login'; $pswd = 'pswd'; $strquery = 'select * from tablename'; // 1. $conn1 = mssql_connect( $servername, $user, $pswd ); mssql_select_db ( $dbname, $conn1 ); // 2. step2( $servername, $dbname, $user, $pswd, $strquery ); // $conn1 is still a valid resource. // 2a. step2( $servername, $dbname, $user, $pswd, $strquery ); // 3. $result = mssql_query( $strquery, $conn1 ); if( !$result ) echo "Step 3 FAILED: $php_errormsg <br>"; else // print the recordset // connect/disconnect function step2( $servername, $dbname, $user, $pswd, $strquery ) { $conn2 = mssql_connect( $servername, $user, $pswd ); mssql_select_db ( $dbname, $conn2 ); mssql_close( $conn2 ); } Expected result: ---------------- The query is processed successfully and the recordset is printed. Actual result: -------------- "Step 3 FAILED: $php_errormsg" is printed; ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26465&edit=1
