How do you properly close a php session before closing the browser?
say the user closes your site (tab or browser) and you want the session to be destroyed because you dont want an active session when the user turns their browser back on and goes to your page. How do you detect them leaving your site to close the active session?

The best way to implement a "Remember Me" function for login in php
I'm currently working on a remember me functionality for my login page and i know the common way is to use setcookie() then $_COOKIE['<some field here>] and assign a value and check that to login, but is there a better way or a safer way?

Bash Script to check for a vulnerable version of `xz` utils
A supply chain attack happened to opensuse recently and it was due to a malicious code inside the xz utils github. Please read up on the issue with your respective repo and backup the version to a previous if not patched. Here is a script to check if your system is vulernable. Shared from a friend in my linux discord.
#! /bin/sh

set -eu

# find path to liblzma used by sshd
path="$(ldd $(which sshd) | grep liblzma | grep -o '/[^ ]*')"

# does it even exist?
if [ "$path" == "" ]
then
echo probably not vulnerable
exit
fi

# check for function signature
if hexdump -ve '1/1 "%.2x"' "$path" | grep -q f30f1efa554889f54c89ce5389fb81e7000000804883ec28488954241848894c2410

Handling sessions with php question
For my project id like to start the session after they are successfully logged in and transferred to their userpage. I'm curious though how to store the session like do I use the user_id assigned to some other id or something in order to keep track of it being active. I tried reading the php docs on it but I got a bit confused. Any insight on handling sessions is most welcomed. I'll share my code for my login page so others can let me know if im doing this wrong. Thanks!

dynamic file names for php like in js can it be done?
you know how in js you can have file names like [id].js where id is a field from a database for pages that are changing based on what is pulled from the db? Can you do the same for php like [user_id].php for a building something like a individual user page?

Database setup for a simple login and registration page in terms of having a "remember me" function
I'm not sure how to setup my database to have a "Remember me" function in order to handle bypassing login. I know you use a cookie with a encoded string and other stuff but the database setup itself is a bit odd. I'm using a Postgres database and so far here are the fields I thought of...
user_id AUTOINCREMENT INTEGER
email TEXT NOT NULL
password TEXT NOT NULL
date_added DATETIME
is_admin BOOLEAN
user_id AUTOINCREMENT INTEGER
email TEXT NOT NULL
password TEXT NOT NULL
date_added DATETIME
is_admin BOOLEAN
I'm thinking I'll need either a separate table for generating a token for a Remember Me function or as an additional field in this User table. Not sure since I've never implemented one before. Any suggestions would be great! Thanks!

When to use htmlspecialchars vs filter_input ?
im confused when using htmlspecialchars vs filter_input for preventing bad input into php. I have got the hang of using prepared queries but I've not noticed when using the other two mentioned functions. Is htmlspecialchars mainly for outputting html to prevent XSS and is filter_input for handling the user input to prevent it from going through to cause harm?

Docker dev containers or ways to use docker without installing development tools on host machine
I've heard dev containers with vscode can make isolated dev environments but it's still a little new. I'm curious how to use docker (with compose as well) in order to make dev environments where I dont have to install various programming languages and their tools on my machine. Anyone have experience with this?

tools that might help overcome design, color, and css issues for projects
sadly I just stink at CSS, layouts, and colors and other design things. Who would've thought that building a bunch of boxes could be some troublesome :P. I've been trying to figure out things and I've been trying to get those skills together with each project but it never clicks. With that being said, is there any tools that can help with design, colors, and the css side of things so I can focus more on the BE and some FE for any full stack projects I do?
