The solution is to not multi-post.

I write at php groups (three), but
for this problem, which is the better newsgroup?

It's ok to write to all of them -- but do a cross-post instead of a
multi-post. It's actually less work for you and you won't piss
everybody off. If you don't understand the difference read this (it's
one of many websites on the subject):

this !is array is obj
if you have 2 value or more in une array
use "bidimensional array" alias of matrix

bidimensional array:
$pippo['a'][0] = "pippo0";
$pippo['a'][1] = "pippo2";
$pippo['a'][2] = "pippo2";
$pippo['a'][3] = "pippo3";

or
$pippo['a'] = array("pippo","qui","quo",...)

<?

class a_rray{
var $me=array();

function intersect_name($value,$value2){
$varname = array_intersect($value,$value2);
$str ="";
foreach($varname as $key =>$value){
$str .= $key." ".$value;
}
return $str;

}

}

$array2[0]='b';
$array2[1]='e';

$cc= new a_rray();
echo $cc->intersect_name($array1,$array2);
