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 could achieve this result?

 

$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);

try to custom function

function my_unique($array){
$k = array_keys($array);
$r = array();
for ($i = 0; $i < count($k) - 1; $i++){
	for ($j = $i + 1; $j < count($k); $j++){
		if ($array[$k[$i]] == $array[$k[$j]]) $r[] = $j;
	}
}
$r = array_unique($r);
foreach ($r as $k) unset($array[$k]);
return $array;
}

$actions = my_unique($actions);
