array_unique and my duplicates

[gogles]

I have a problem with the array_unique function.

Without the array_unique function the results are:

jessica alba and natalya are friends. 2008-05-13
jessica alba and lars ulrich are friends. 2008-05-13
jessica alba and natalya are friends. 2008-05-13
jessica alba and lars ulrich are friends. 2008-05-13

And with the array_unique function:

jessica alba and natalya are friends. 2008-05-13

The desired result would be.

jessica alba and natalya are friends. 2008-05-13
jessica alba and lars ulrich are friends. 2008-05-13

Any ideas on how i could achieve this result?

PHP Code:

$actions = array();
  
  while ($row = mysql_fetch_array($result_1)) {    
    $actions[] = array("name" => $row["m_name"],
                       "name2" => $row["m2_name"],                               
                         "date" => $row["epoch"]);
  }
  
  while ($row = mysql_fetch_array($result_2)) {
    $actions[] = array("name" => $row["m_name"],
                       "name2" => $row["m2_name"],                                   
                         "date" => $row["epoch"]);
  }
  while ($row = mysql_fetch_array($result_3)) {
    $actions[] = array("name" => $row["m_name"],
                       "name2" => $row["m2_name"],                                   
                         "date" => $row["epoch"]);
  }
  while ($row = mysql_fetch_array($result_4)) {
    $actions[] = array("name" => $row["m_name"],
                       "name2" => $row["m2_name"],                                   
                         "date" => $row["epoch"]);
  }
 
  $actions = array_unique($actions);

This seems to have worked...

PHP Code:

function multi_unique($array) {
    foreach ($array as $k=>$na)
        $new[$k] = serialize($na);
    $uniq = array_unique($new);
    foreach($uniq as $k=>$ser)
        $new1[$k] = unserialize($ser);
    return ($new1);
}
