Subject: [PHP] VERY basic function question

I'm trying to learn functions (just started). I can't see why this fails:
?php
function count($var)
{
if ($var == 10){
$result = $var + 10;
return $result;
}
else {
$result = $var + 20;
return $result;
}
}
$setvar = 10;
count($setvar);
echo $result;
?

I probably just didn't understand my manual. Any ideas?

Thanks
-Will

You cannot use count as a function name - count() actually does
something - see the php manual

 {
 if ($var == 10){
 $result = $var + 10;
 return $result;
 }
 else {
 $result = $var + 20;
 return $result;
 }
 }
 $setvar = 10;
 count($setvar);
 echo $result;
 ?

This is what you may want:

?php
function my_count($var)
{
if ($var == 10){
$result = $var + 10;
return $result;
}
else {
$result = $var + 20;
return $result;
}
}

$setvar = 10;
echo my_count($setvar);
?

And another thing
Let say you called you function count1

Change :
count1($setvar);
to :
$result = count1($setvar);
echo $result;
