#34137 [Bgs]: assigning array element by reference causes binary mess

ID: 34137 User updated by: rashid at ds dot pg dot gda dot pl Reported By: rashid at ds dot pg dot gda dot pl Status: Bogus Bug Type: Arrays related Operating System: windows xp PHP Version: 5CVS-2005-08-15 (snap) New Comment: how can something that crashes web server be a bogus? var_dump shows that $arr1['alfa'] is null, which is also not true. The array is left in messed-up state after the assignment and lines after that the script suddenly crashes. If you access the same variable in two different ways and you see two different values, than something isn`t right. There should be at least notice/warning/error on the line with assignment when assigning to the same variable or documentation note if it is not allowed.

(hint: Try var_dump() on it..) ------------------------------------------------------------------------ [2005-08-15 17:28:35] rashid at ds dot pg dot gda dot pl Description: ------------ If you have an array which contains another array and you`ll assign reference to the inner array to the variable containing the outer array youll see all kinds of binary trash. With bigger arrays Ive also seen Apache crashes.
