Function and a thousand $vars..

Anon

i'we got many vars, all starting with $foo, just the end is diferent ($foo1, $foo2, $foo3, $foo4,...)..

is there any simple way to use all in some function, i don't want to type:

Function blah ($foo1, $foo2, $foo3,...),

It must be something like, i dunno:

Function blah ($foo*) or Function blah ($foo&)..

thank you for your answer,

How about, getting all the $foo* in an array and passing the array to the function.

myles

Set up an loop with a counter.

You can manipulate the name of the variable for each pass in the following way:

foo = ${sprintf("foo%d",$counter)};

I don't know if this is the best way, but it worked for me.

well..

it looks like i must make array improvements.. but i need help.. i readed manual, searched for word array and function and i still don't know how to work with arrays (must i tell you that i don't understand arrays in c++?) 😃

anyway..

i'm begging for my example..

old way: 1st i maked $vars, named $choose with $i behind, where $i is incrasing number from 0 >.. now, i tought you can make all $choose1, $choose2, $choose3,... in a simple function, dunno, like $_choose&, but it looks, that function doesn't exists, so..

how then with arrays and how to look, loop them?

please give me one example, but not like that one in manual..

insert number into array??
$foo = array(????);

Function blah ($foo???) {
$i = 0;
while ($i < $somevar) {
if ($arrayfield1 == 24) { echo "🙂"; }
$i++;
}
}

can you show me on this example?? if you understand... thank you very much.. apretiate it..

Hey,
You kind of over-confused me here, but if you are looking at making an array and passing it as a parameter to a function, here you go.
I assume you store your variables as
$foo0,$foo1,$foo2.......$fooN.
, so your array will be filled as
$fooArr[0] = $foo0;
$fooArr[1] = $foo1;
.....
...
....
.....
$fooArr[N] = $fooN;

Now the logic is as simple,
$fooArr = Array();
for($i=0;$i<=$NorN;$i++)
$fooArr[count($fooArr)] = ${foo.$i};
MyFunct($fooArr);

This would that simple.

I hope i got your question correct.
