Re: [PHP4BETA] What Happened to my object hierarchy ???

How recent is your cvs build? Please update it again and do a make clean before recompiling. Let us know if you still have the same problem. Any chance, of cutting down the problem a bit more? It's quite a lot of code. Thanks, Andi At 10:30 PM 10/7/99 +1100, Alan van den Bosch wrote:

Hi,

    Here is a curly one... I'm using  recent cvs DSO build of php4beta on rh6.0

and I noticed the problem about a week ago, but it has taken a while to track down. I have found that in certain circumstances the contents of arrays get mutilated for 'no apparent reason' (not that I can see anyways...). I have isolated the behaviour, check out the following (also attached) example code, around line 55. --------- <?php class part{

        function part($args=""){
                $this->properties=array();

                reset($args);
                while($cur=each($args)){
                        $this->prop($cur['key'],$cur['value']);
                }
        }

        function prop($var,$arg){
                if (!isset($arg)){
                        // single argument, return current value
                        return $this->properties[$var];
                }

                // set and return new value
                return $this->properties[$var]=$arg;
        }

        function show($indent=""){
                echo "${indent}Properties of ".$this->prop("name").":\n";
                $indent.="\t";
                reset($this->properties);
                while($cur=each($this->properties)){
                        //ignore index 'obj'
                        if ($cur['key']!="obj")echo "${indent}${cur['key']} = ${cur['value']} \n";
                }
        }

} class assembly extends part{

        function assembly($args="",$parts=""){

                // call base constructor
                $this->part($args);
                $this->properties['obj']=array();
                // add parts
                $this->add($parts);

        function add(&$parts){
                reset($parts);

//                              $name=$cur['value']->properties["name"];

// // this method of setting $name kills the contents of $this->properties...

                                $name=$cur['value']->prop("name");

// $this->properties['obj'][$name]=$cur['value'];

                        }
                }
        }

                $indent.="\t";

                while($cur=each($this->properties['obj'])){
                        if (is_object($cur['value'])){
