#21312 [NEW]: session_register doesnt like null values

From: charlesk@netgaintechnology.com Operating system: Windows 2000 Server PHP version: 4.3.0 PHP Bug Type: Session related Bug description: session_register doesnt like null values <?php session_start(); $source = $_SERVER["HTTP_REFERER"]; session_register("source"); $connection = mssql_connect('server','UserName','password'); $sql = "select * from tbl;"; echo "$sql $connection<br>"; $sql_result = mssql_query($sql,$connection); $num = mssql_num_rows($sql_result); $retVal = "Records = ".$num; if ($num > 0) { mssql_data_seek($sql_result,0); $row = mssql_fetch_object($sql_result); $retVal = $row->Text; } mssql_free_result($sql_result); echo $retVal; ?> In this case the mssql_query fails with: PHP Warning: mssql_query(): supplied argument is not a valid MS SQL-Link resource. if I simply comment the $source = $_SERVER... it succeeds. If I change session_register to $_SESSION["source"] = $source; it succeeds. I am not sure how these are related. What is even weirder is the echo "$sql $connection<br>"; They echo what is expected when it works. When it doesnt whichever was defined first is the value for both. IE When it fails as it is written select * from tbl_Texts; select * from tbl_Texts; If you change $connection = mssql_connect('server','UserName','password'); $sql = "select * from tbl;"; to $sql = "select * from tbl;"; $connection = mssql_connect('server','UserName','password'); it echos Resource id #3 Resource id #3 I will in the future use $_SESSION but there are alot of files to change if this wont be fixed.
