php: Redirect to previous page.


Question

PHP Learners Diary, Day 6:

I have a login and logout script. The script can be called from any page within the entire site.

So how can I make it so that if the user was on Page A and clicked logout, they went back to Page A after the logout, and if they were on Page B they would be returned to Page B after the logout?

I'm aware of the Header ("Location: etc etc... but that doesn't seem to be the appropriate way here as I don't know what page they are calling from.

Thanks in advance, once again, for any help provided.

    • To be fair, I haven't seen a BSOD since years ago, seriously. Windows has been pretty stable for me always.
    • Nobody is "shoving" anything down anybody's throats. The feature is turned off by default, so the user needs to explicitly enable it. How is that "shoving down" anything? Again: this is OPT-IN. If you don't like the feature for whatever reason, just ignore it or turn it off if you already enabled it.
    • Kioxia is Toshiba rebranded? Did not know that. 
    • I use to buy only Samsung and Crucial MX but things have change a lot in the last 5 years.   Western Digital Black ssd are very good. Corsair MP too (specially when it comes to gen 5) The Patriot 2TB Viper VP4300 Lite is a good cheap option with decent perf Crucial Txxx is pretty good too. I had bad exp with TeamGroup when they initially came out but i bought two TEAMGROUP T-Force Vulcan Z 2TB SLC Cache for my new computer because they were the cheapest 2 tb with any kind of cache and i've been pleasantly surprised.   You got to do your own research. Does it have dram cache? If yes which type of dram cache. Does it have a large SLC cache? If so how large is it? 20% of the drive? 30% of the drive? For example the TG 2TB i posted above has a 650GB SLC cache which is about 30% of the drive capacity. Is it TLC or QLC. I'd avoid QLC drive without any type of cache unless it's for storage they tend to perform badly with small writes. I'm not an expert so do your own research  https://www.techpowerup.com/ , https://www.tweaktown.com/ and https://www.tomshardware.com/ are usually good sources to know the real spec of a ssd and nvme specially the cache since a lot of manufacturer are not clear about this.
