returning value to variable

hi

i need returning value of function as a variable

example :

function 1 () {
return "some error";
}

function 2 () {
$v = 1();
if ( $v != '' ) echo "error";
}

it doesn't work this way
this works : echo 1();
but i need the string value as a variable

thanks

Are you using 1 and 2 as the function names in your real application?
Hope not, because function names same as variable names in all languges
can not begine with digit. Your 1 and 2 functions not work in my
computer either, but they start to work after I have changed 1 and 2 to
a and b respectively.

of course not, it was an example

btw. i has already solved the problem
it was a stupid fault, i returned the value of the function
but i didn't print it in the main code, so i thought
that something's wrong
