Ciao a tutti,
ho un problema con uno script in php5...non posso utilizzarlo perchè devo metterlo su aruba ed aruba non supporta il php5 ma solo il 4. Dovrei adattarlo al php4 sempre se è possibile...ma spero tanto di si!!
L'errore me lo da nella pagina 1 in questo punto
function w() {
if($this->sons == NULL)
return 1;
$sum = 0;
for($i=0; $i<$this->sons->countSons(); $i++) {
$sum += $this->sons->at($i)->w();
}
return $sum;
}
ed è questo:
Parse error: parse error in c:\programmi\easyphp1-8\www\magda\tree\Node.php on line 31
Linea 31: $sum += $this->sons->at($i)->w();
posto le tre pagine che formano il mio script... questo script serve per generare una sorta di diagramma di flusso.
-------------------------------------------------------------------------------
pagina uno: Node.php
<?php
require_once("NodeList.php");
class Node {
var $content; // int char string...
var $sons; // NodeList
function __construct($c) {
$content = $c; // int char string ...
$sons = NULL; // NodeList
}
function addSon($son) { // $son : Node
if($this->sons == NULL) {
$this->sons = new NodeList($son);
$this->sons->content = $son;
$this->sons->next = NULL;
return;
}
$this->sons->add($son);
}
function w() {
if($this->sons == NULL)
return 1;
$sum = 0;
for($i=0; $i<$this->sons->countSons(); $i++) {
$sum += $this->sons->at($i)->w();
}
return $sum;
}
function h() {
if($this->sons == NULL)
return 1;
$max = 0;
for($i=0; $i<($this->sons->countSons()); $i++) {
$sonh = 1+$this->sons->at($i)->h();
if($sonh > $max)
$max = $sonh;
}
return $max;
}
function printNode() {
echo "".$this->content." w:".$this->w()." h:".$this->h()."
";
if($this->sons != NULL) {
for($i=0; $i<($this->sons->countSons()); $i++) {
$this->sons->at($i)->printNode();
}
}
}
}
?>

pagina 2: NodeList.php
<?php

$this->next = NULL;

return $this->content;
if($this->next == NULL)
return NULL;
$i--;
return $this->next->at($i);
}
function add($n) { // $n : Node
if($this->next==NULL) {
$this->next = new NodeList($n);
$this->next->content = $n;
$this->next->next = NULL;
//$n->next = NULL;
return;
}
return $this->next->add($n);
}
function remove($n) {
// TODO
}
function countSons() {
if($this->next == NULL)
return 1;
return 1+($this->next->countSons());
}
}
