If you place assignments between registering data, you can't: 1) to a static varable ex.: self::$var you can't register data after that assignments, 2) to local variable $var=$_SESSION you can't register data before and after. But there is workaround you should assign with casting to array: $var = (array)$_SESSION in both cases. Reproduce code: --------------- // 1 - seperate code $_SESSION["test1"] = "test1"; self::$var = $_SESSION; $_SESSION["test2"] = "test2"; // 2 - seperate code $_SESSION["test1"] = "test1..."; $var = $_SESSION; $_SESSION["test2"] = "test2..."; //workaround $_SESSION["test1"] = "test1..."; $var = (array)$_SESSION; self::$var = (array)$_SESSION; $_SESSION["test2"] = "test2..."; Expected result: ---------------- I expect register data to $_SESSION after assignments $_SESSION to some variable. Actual result: -------------- It's not ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39496&edit=1
