Why would the following function not return a value: (both $lastname and
$firstname are defined)
function get_handle($lastname, $firstname)
{
$handle_guess=$lastname;
$handle=array();
$fp=fopen('../truelies/userdb', "r");
while ($d=fgetcsv($fp, 250, ";")) {
$handle[] = $d[0];
}
fclose ($fp);
for ($i=0; $i<count($handle); $i++) {
if (strcmp($handle_guess, $handle[$i]) ==0) {
$j=1;
$handle_guess = $handle_guess . substr
($firstname,0,$j);
$j++;
}
}
return $handle_guess;
}
if I put an echo $handle_guess before or after the function then
nothing. So far the only way to make it work is
echo get_handle($lastname, $firstname);
which is not beautiful.
BTW is there a limit to the length of a command. If I can't figure this
out then I will have five or six of this "echo" statement concatanated
together.
