Function Dynamic Variable variables

zapa

I read, manual,
http://www.php.net/manual/en/language.variables.variable.php

Is it ok to Dynamic Varible via Functions?

i.e

// make function to make dynamic variable 

function name ($something){ 
$$something = $seomthing;
}

name ("test"); // call function

echo ${$test}; // should Print "test" but it dont.

also tryed it useding return inside the function no luck?

anyhelp be grate! thanks!

Well, $test is not within the global scope. If you do: $test = name('test'); it will work, but obviously that doesn't serve its purpose. You could global $test within the function and it should work, however.

what i am wanting it do is make a Veriable Palce holder by useing a function

$test = Dynamic Veriable generated by the funcation so why would i put gloabl $test if i dont know what $names i will need to put when i make a function.?

they are saying to do something like...

// make function to make dynamic variable 

function name ($something){
//not sure if this would actually work... but...
global ${$something}; 
$$something = $something; //fixed your spelling typo "seomthing"
}

name ("test"); // call function

echo $test; // should Print "test" -- no need to ${$here} since your are literally setting $test = "tesT" in your function

because you can declare a global variable from within the array with the $GLOBALS array

function foo()
{
    $GLOBALS['fish']='chips';
}

foo();
echo $fish;

would output chips. Can you tell us a bit more about what you're trying to do as it might help.

$GLOBALS['fish']='chips'; medthod works betters thanks for poting that out!
