recursion problem

[Anon]

Hi!

This code generate the error message:
"Fatal error: Cannot redeclare count()" ?

Maybe someone could help me correct the code?

function count($x) {
if ($x<10) {
$x++;
count($x);
}
else {
return $x;
}
}

$a = count(0);
echo($a);

Thanks
Markus

Hi,

there is a native PHP function named count() which counts the entries in an array.
Just pick another name for your function.

Hi,
just a suggestion...
instead of the if statement why don't you use a while?

function countxs($x){
while ($x<10) {
$x++;
}
return $x;
}

$a = count(0);
echo($a);

same thing, less code lines, neatter

Ok. Another function name solved (almost) one of my problem. Thanks.

Anyway, the code below makes me confused.

function countxs($x) {
if ($x<3) {
$x++;
echo($x.", ");
countxs($x);
}
echo("<br>send: ".$x);
return $x;
}

$a = countxs(0);

echo(" ==> recived: ".$a."<br>");

It will produce an output like this:

1, 2, 3,
send: 3
send: 3
send: 2
send: 1 ==> recived: 1

I would have excpected this:
send: 3 ==> recived: 3

If I use this code instead (that's the same as in my first message, except for the function name) I get even more confused.

function countxs($x) {
if ($x<3) {
$x++;
echo($x.", ");
countxs($x);
}
else {
echo("<br>send: ".$x);
return $x;
}
}

$a = countxs(0);

echo(" ==> recived: ".$a."<br>");

It will produce an output like this:

1, 2, 3,
send: 3 ==> recived:

So, how could I get a (recursive) function that behaves as I excpect?
