Example:
$x=array('a'=>' ant','b'=>'boat ');
$s='a';
$y='$s';
echo $x[$$y];
I want to echo the value of key 'a' by indirectly referencing it via the
variable $y. The above is NOT correct, I know.
How do I indirectly reference a variable in PHP?
TIA,

$y='s';
fix your example, but I don't understand why you can't use 'echo $x[$s];' .

The technique is called 'Variable variables' and looks like this:
$x=array('a'=>' ant','b'=>'boat ');
$s='a';
$y='s'; // Removed the dollar sign
echo $x[$$y];

That's the structure that I'm looking for.
Thanks.

Hi,
What C statement(s) would translate to indirect jmp in assembly? I know
that function pointer invocation would translate to indirect 'call'

Hi, I was looking for your opinion on VB.NET - its long-term
prospects, etc. Sorry this is vague, but it's not meant to be a troll.
It's a pro-VB.NET post actually.
I haven't used VB or VB.NET really, but I have used Realbasic (a vb
clone), Java, C#, C, and Python.
I work in education, and I'd like something that is easy enough for
teachers and students to use to develop real, usable applications, not
just to learn programming for...

Hello I need some ideas for designing a recursive function for my ray
tracing program.
The idea behind ray tracing is to follow the electromagnetic rays from
the source, as they hit the object.The object is triangulated. The
rays can undergo multiple reflections, diffractions etc of the same
object i.e. a ray hits a surface of the object, undergoes reflection
resulting in a reflected ray which can again hit a surface, corner or
edge...

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:

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,...
