PHP puts most of its functions into a big flat global namespace.
That leads to short function names - but creates a namespace
minefield for programmers.
Lots of the functions are legacies from the days before PHP
got object-oriented features.
For instance we currently have:

Hi,
I'm getting linking errors when I declare a variable in the
global scope, but not inside a function. The declarations
are the same (only the names have been changed...).

I'm learning Javascript. I downloaded a script for study. Please tell
me how the variable "loop" can have scope in the first function when
it is altered in the second function? It is not defined in global
space, therefore it is not a global variable, yes? Even if it was
global, how would it get from one function to another? In PHP
variables are copied by value. Are they copied by reference in
Javascript?

I've read some posts indicating that having tons of GV's in
an Access app is a bad idea. Personally, I love GVs and I
use them (possibly abuse them) all the time for everything
imaginable - have been for years. If the machine has memory
to spare and windows can use it - I'm thinking "Why not?"
I was wondering what some of you have to say about that,
particularly any severe "gotchas" you've had the unfortunate
experience to contend with.

Hello,
there were times when I used to be looking for a way to access
JavaScript Global object similar to those found in VBScript or PHP
($GLOBALS). At present this has only academic value for me. I was doing
research on JavaScript inheritance recently (simplifying it in
particular) and after reading 10.1.1, 10.1.3 and some other sections of
ECMA262 I got a hint on accessing global object from different than
global scope.

A global variable is really just a property of the "Global Object", so
what does that make a function defined in the global context? A method
of the Global Object?
http://developer.mozilla.org/en/docs/Core_JavaScript_1.5_Guide:Defining_Functions
doesn't actually give any insight.

The opinions expressed in this article are those of the author alone although many have...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
