Folks,
Ever since reading an interesting article in Linux Format on PHP whereby
suggested code writing was made that could enhance performance on a server,
I've started testing various bits of code everytime I found more than one
method to perform a single task. I timed each method to find which would
complete faster. I thought I'd share my most recent results which (I
believe) should help those write their programs to be more...

What about an enhancement of foreach loops which allows a syntax like that:
foeach(int i in 1..10) { } // forward
foeach(int i in 99..2) { } // backwards
foeach(char c in 'a'..'z') { } // chars
foeach(Color c in Red..Blue) { } // using enums
It should work with all integral datatypes. Maybe we can step a bit further:
foeach(int i in 1..10, 30..100) { } // from 1 to 10 and 30 to hundred

Summary: Use foreach(..) instead of while(list(..)=each(..)).
--==--
Foreach is a language construct, meant for looping through arrays.
There are two syntaxes; the second is a minor but useful extension
of the first:
foreach (array_expression as $value)
statement

I'm looping through the keys and values of a form submission using
foreach($_POST as $key => $value)
echo "$key = $value<br>";
No problems there. All works as expected. But seveal of the values are
arrays and the echo comes out like:
subjectone = Array
subjecttwo = Array

This is a very simple question, but for moe reason I can't find an answer.
Do I take a performance hit if a foreach statement has to evaluate an
expression?
For example, consider the following:
foreach (DataColumn column in view.Row.Table.Columns)
{
// Do something
}

Hi,
I'm trying to use nested foreach loops to loop through two arrays.
Each element in the first array corresponds to another array. The
brandcode part of the first array is the same as the name of the
corresponding array.
Basically, one array is of the brand info, and the second is of the
cars made by that brand.
To loop through all the brands, and then print their corresponding
cars, I tried:
foreach ($brands as $curbrand) {

Is it safe to remove elements from an array that foreach is working on?
(normally this is not the case but not sure in php) If so is there an
efficient way to handle it? (I could add the indexes to a temp array and
delete afterwards if necessary but since I'm actually working in a nested
situation this could get a little messy. I guess I could set there values to
null and remove them afterwards?
Thanks,
Jon

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...

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...
