Do I need to use curly brackets in PHP if .. else statements? other constructs?
Does it matter? What are Best Practices? Why?
thanks in advance...
This seems to work WITHOUT curly brackets:
if(ereg("Win", getenv("HTTP_USER_AGENT")))
$visos = "Windows";
elseif((ereg("Mac", getenv("HTTP_USER_AGENT"))) || (ereg("PPC",

If I use the curly bracket syntax (referred to as the
complex syntax) within a string, how do I get to call a
function within it?
The php manual says that the first (or previous)
character for the curly bracket has to be a dollar sign '$'.
This is fine for variables, arrays and some objects but
doesn't allow me to call a function such as addslashes() or
trim() before I return the string in the variable.

While reading the C++ tutorial in this page:
http://www.cplusplus.com/doc/tutorial/tut2-2.html
I'm astonished to learn that we could omit curly brackets in function
declaration for single instruction as is written in the paragraph:
"statement is the function's body. It can be a single instruction or a
block of instructions. In the latter case it must be delimited by curly
brackets {}."
But I'm not sure if this is true. At least with...

such that when i use the macro like this:

I'd like to know how the preprocessor treats curly braces, as compared
to how it treats parentheses.
What happens if I pass this:
{ a_function( arg1, arg2, arg3 ) }
as an argument to a function macro? Does it get passed in whole, or
split into smaller parts like so:

Hi, I've got some PHP code that looks like this
$cura= ord($data{$pnum*2});
$curb = ord($data{$pnum*2+1});
Notice the curly braces -- does using them make any difference, or will
square brackets do the same thing?
Thanks

Hi everybody,
I'm a PHP beginner, so please forgive me for this question.
I am working on code someone else wrote a long time ago. The code was written without curly braces in many places, which for the most has been ok. However I am getting an error message that -for the code snippet I posted below- would read like this:
Notice: Undefined variable: f in ... on line 3.
Precisely a section that has a couple of loops and conditionals...

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,...
