[PHP] Variable (naming them) Functions.
Hello everyone:
I was wondering, does anyone of you know a method to declare a function
(give it a name) basing on a value acquired during run time?
I tried using the syntax as of a variable function call:
snip
$fname = 'hello';
function { sprintf(%s, $fname) }($arg='') {
Return I named you : $fname;
}
echo $fname($fname);
# no luck...
function {$fname}($arg='') {
# nope...
function $fname($arg='') {
# neither...
/snip
and so on... all parse errors...
Any way to do it?
I am looping an array with some function names checking if a function was
declared already, and if not then declare, if yes - give a different name.
I also went through these bibles:
http://www.php.net/manual/en/ref.funchand.php
http://www.php.net/manual/en/ref.funchand.php
but found nothing that helps.
Thanks in advance,
Sincerely,

[PHP] Variable (naming them) Functions.
got a typo in my previous post:
I was trying this:
$fname = 'hello';
function { sprintf(%s, $fname) }($fname='') {
Return I named you : $fname;
}
echo $fname($fname);
But that doesn't matter...
Thanks,
waiting for your help.

Why not use classes? If I understand you problem correctly, I think classes
should solve your problem. Right?

RE: [PHP] Variable (naming them) Functions.
no classes CAN'T solve my problem:
it is an abstraction layer. called as func_hello(); I want, inside
func_hello() {} declare a new function based on what happened before
func_hello() was called. In other words: I of course though about classes,
and there is in fact a work around, but I need to know if 'function
$var($arg) { return; }' syntax exists and what it is.
in the docs there's nothing being said.

create_function seems not letting you choosing it's name. am I right, or there's a way to say: create_function($name.$to.be, args, args, args)?

RE: [PHP] Variable (naming them) Functions.
It lets you choose the variable name which you use when referencing the
function, but the actual function name is set by PHP (as lambda_1, lambda_2,
etc.)
?
$test=myFunction;
$$test = create_function('$a,$b','return log($a * $b);');
echo myFunction is .$myFunction(2,2).br;
?

http://php.net/create_function
(maybe together with a little wrapper:
$foo = create_function (...);
$FNames [$var] = $foo;
function delta ($FuncName, $args) {
return ${$FNames[$FuncName]} ($args);
}
)
But such a thing is an ugly hack and I'm sure you don't need it.

RE: [PHP] Variable (naming them) Functions. DONE! DONE! DONE!
Guys,
I think LORD just looked down here in Tokyo, seen me still typing at 3.15am
of Friday night, smoking the third pack of that nasty Marlboros, having no
dinner, with no even a cup coffee remained... and sent to the list that
GENIUS of Jason Murray who solved my problem.
I know, Jason, you didn't mean it, but it REALLY helped me:
$fname = 'hello';
$func = sprintf(
function %s(\$v='') {
Return \\$vBR\;
},
$fname
);
eval($func);
echo $fname('Please print it please');
// And it did!
a dynamic function! I got it.
with eval() I can call it as I wish!
I have no idea, HOW ON THE EARTH could I ever forget about magic EVAL().
I solved it!
Everyone, take a note of this code, as it causes some sleepless nights and
'unhappy' girlfriends to some people. :-)
Thanks everybody,
Jason and Oliver in particular!

RE: [PHP] Variable (naming them) Functions.
no, I knew that,
my problem was generating functions with dynamic names.
I solved it with a simple eval(), see my last post below;
