php - How does remember me cookie work with session life time? -


i'm bit confused this,

say session has been started default php ini settings gc_maxlifetime 1440 seconds. , supposed use remember me functionality this, set cookie lifetime 14 days. long session max life time set 24 minutes lesser cookie life time (14 days), after 10 days (for example) session (of course depends on gc probability) expired , have no reference session id remember me cookie has.

so how setting remember me cookie lifetime longer session lifetime remember/resume session? or need change session max lifetime according cookie lifetime?

generally "remember me" cookie persistent cookie, not session cookie. contains encrypted information allows automatic login action occur. i.e. when there no active session already, "remember me" cookie present, new session started.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
