Question

I’m trying to create clones of an element in an object and set new names for the clones.

class My_Obj{
 var $obj;
 var $obj_name;
 var clone;      //----int input to say how many clones are needed
 var clone_names;//----array input to make clone's name different from $obj
 function __construct( $args = '' ) {
   $defaults=array(
   /* codes to set up the default $obj */
  )
if ( $this->clone >0 ){
  for ( $i = 0; $i <= $this->clone; ++$i ){
   $clone_obj[$i]['name'] = /* need to loop through array $clone_name to fill this */

}
 }

/* other codes */
}

The $clone_names, for example, can be array(‘cat’, ‘dog’, ‘bird’). It doesn’t matter which order as long as each clone get a name. I would like to learn how to do this. Thanks!

Answer 1

If I understand your question correctly, you want to fill the array $clone_obj with values from $clone_names – up to the number of clones specified in $clone?

If that’s the case, this may work (I’ve rewritten the sample class you used):

class My_Obj {
    public $clone = 0;          //----int input to say how many clones are needed
    public $clone_names = array();  //----array input to make clone's name different from $obj
    private $clone_obj = array();   // array to store cloned names in

    function __construct($args = '') {
        for ($i=0; $i<$this->clone; $i++) {
            // copy the name in "$clone_names" to "$clone_obj", if it exists
        $this->clone_obj[$i] = array();
            $this->clone_obj[$i]['name'] = (isset($this->clone_names[$i]) ? $this->clone_names[$i] : '');
        }
    }
}
