php - array_diff on assoc array only showing the first result and not all -


this continuation question forgot ask full question. luck did because ask wrong question. ok have following 2 arrays

array ( [idasset] => 10000005 [assetname] => hp )  array ( [idasset] => 10000006 [assetname] => hp server )  array ( [idasset] => 10000009 [assetname] => hp laptop )  array ( [idasset] => 10000010 [assetname] => office printer )  array ( [idasset] => 10000023 [assetname] => test )      array ( [idasset] => 10000023 [assetname] => test )

i got these using following code

  $firstarray = array();    $secondarray = array();     do{     array_push($firstarray,$array1);     }while($array1 = mysql_fetch_assoc($assetup));   do{ array_push($secondarray ,$array2);  }while($array2 = mysql_fetch_assoc($docup));  $array3 = array_diff_key($firstarray, $secondarray);  print_r($array3);

however leaves me following:

  array (    [2] => array ( [idasset] => 10000006 [assetname] => hp server )    [3] => array ( [idasset] => 10000009 [assetname] => hp laptop )    [4] => array ( [idasset] => 10000010 [assetname] => office printer )    [5] => array ( [idasset] => 10000023 [assetname] => test ) )

it seems leaving out first loop , still including test asset

i'm trying left 1 array not include items found in both arrays. example above 10000023 test removed both arrays leaving me first 4 rows $firstarray (this why first question have been wrong) want differences not similarities.

i assuming, arrays follows:

$data = array( array( "idasset" => 10000005, "assetname" => "hp" ),                array( "idasset" => 10000006, "assetname" => "hp server" ),                ... );

array_diff_assoc not going check sub arrays. in case compare numeric indizes isnt need.

a idea might use idasset want compare array key:

$data = array( "10000005" => array( "idasset" => 10000005, "assetname" => "hp" ),                "10000006" => array( "idasset" => 10000006, "assetname" => "hp server" ),                ... );

if compare them via array_diff_key, return differenced in key only. , since that's criteria ... voilá
