Who is using chroot with php-fpm? Is it worth it?
I don’t use chroot, but the default setup for modern versions of FPM already compartmentalizes everything adequately for example, the private /tmp directory. I agree with others that chroot is an outdated way of doing things.
Also, I use SELinux…yet another way of achieving many of the same goals of chrooting. I’d highly recommend setting up SELinux if you are not already using it. If you’re concerned enough about security that you’d even think of chrooting php-fmp, you probably want to set up SELinux and have it on «Enforcing» (it’s useless on «Permissive» mode, that’s really only suitable for the configuration phase of test servers.) Not only will it provide security with PHP, but you get a whole bunch of other security benefits of it.
I have done some pretty sophisticated things with a web server under SELinux, requiring me to manually change a number of policies, and while I have had a few prolonged sessions of frustration, maybe 3-4 hours at a time of banging my head against the wall trying to get the permissions set up properly, it is totally worth it. It’s all up-front work, and once you learn how to do it it’s very easy.

Set array pointer to a specific key or value in PHP
What PHP lacks is the ability to set the array pointer to an arbitrary key or value. There are ways to move forward and backward in the array but not a dedicated function to set the internal pointer to a specific key. Fortunately we can make it work, but it’s pretty archiac. We’ll need to loop through the array and look for what we want.

Format a number with leading zeros in PHP

PHP setcookie “SameSite=Strict”?
You can use the $options array to set the samesite value, for example:
setcookie($name, $value, [
‘expires’ => time() + 86400,
‘path’ => ‘/’,
‘domain’ => ‘domain.com’,
‘secure’ => true,
‘httponly’ => true,
‘samesite’ => ‘None’,
]);
The value of the samesite element should be either None, Lax or Strict.

$str = str_replace(‘ ‘, ‘-‘, $str);
return preg_replace(‘/\-{2,}’, ‘-‘, $str);
}
