Question

I have following arrays :

$t[0] = array('one'=>array('a'=>2,'b'=>3,'c'=>2,'e'=>4));
$t[1] = array('two'=>array('a'=>2,'b'=>3,'c'=>2,'e'=>4));
$t[2] = array('one'=>array('a'=>2,'b'=>3,'c'=>2,'e'=>4));
$t[3] = array('three'=>array('a'=>2,'b'=>3,'c'=>2,'e'=>4));

I want to remove duplicate arrays from above arrays, the result should be :

$t[0] = array('one'=>array('a'=>2,'b'=>3,'c'=>2,'e'=>4));
$t[1] = array('two'=>array('a'=>2,'b'=>3,'c'=>2,'e'=>4));
$t[2] = array('three'=>array('a'=>2,'b'=>3,'c'=>2,'e'=>4));

Thanks

From what I understand what you want to do is remove duplicate keys from a multi-dimensional array.

Something like this should do the trick:

$new_array = array();
foreach($t as $array) {
    foreach($array as $k => $v) {
        if(!array_key_exists($k, $new_array)) {
            $new_array[$k] = $v;
        }
    }
}
