Previous Comments: ------------------------------------------------------------------------ [2005-12-25 17:41:06] sniper@php.net It has to change the input array, because it should convert all the values in strings without separating them to be able to get returned values from stored proc. Needs documenting. ------------------------------------------------------------------------ [2005-03-21 23:04:36] treehousetim at gmail dot com More specifically, all entries in the array are changed to string types. here is more data as requested using var_dump instead of print_r. BEFORE: array(3) { [0]=> int(44) [1]=> NULL [2]=> NULL } AFTER: array(3) { [0]=> string(2) "44" [1]=> string(0) "" [2]=> string(0) "" } ------------------------------------------------------------------------ [2005-03-21 22:45:37] sniper@php.net Please change print_r -> var_dump to get more detailed information out of the $paramList variable. ------------------------------------------------------------------------ [2005-03-21 18:38:28] treehousetim at gmail dot com Description: ------------ Calling odbc_execute modifies the input paramList array. This happens even when I try to make a copy of the array before passing it to odbc_execute. Specifically, null parameters are changed to zero length strings. Reproduce code: --------------- <?php function x( $query, $paramList ) { $result = odbc_execute( $query, $paramList ); $paramList['timg'] = "Tim Gallagher"; } // change the server and database below to the correct values for your setup $connection = 'DRIVER={SQL Server};SERVER=server;DATABASE=database'; $handle = odbc_connect( $connection, '', '' ); $query = odbc_prepare( $handle, "INSERT INTO TEST (ID,CHECK_LONG,CHECK_VARCHAR) VALUES (?, ?, ? )" ); $paramList[0] = 44; $paramList[1] = null; $paramList[2] = null; echo gettype($paramList[2]) . "\n"; // echos NULL x( $query, $paramList ); echo gettype($paramList[2]) . "\n"; // echos string print_r( $paramList ) ?> Expected result: ---------------- NULL string Array ( [0] => 44 [1] => [2] => ) Actual result: -------------- NULL NULL Array ( [0] => 44 [1] => [2] => ) ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32395&edit=1
