PHP配列に少し問題があります。まず、この配列内に配列があり、重複を削除しようとしています。配列のprint_rを実行すると、これが出力されました....

Array (
   [0] => Array ( [creditfeeid] => 318 [client] => Test 1 [adjustment] => 444.00 [issuedate] => 2012-02-10 20:27:00 [isrecurring] => No [comment] => 444 [commission] => 17.76 )
   [1] => Array ( [creditfeeid] => 319 [client] => Test 1 [adjustment] => 333.00 [issuedate] => 2012-02-10 20:27:00 [isrecurring] => No [comment] => 333 [commission] => 9.99 )
   [2] => Array ( [creditfeeid] => 320 [client] => Test 1 [adjustment] => 111.00 [issuedate] => 2012-02-10 20:27:00 [isrecurring] => No [comment] => 111 [commission] => 1.11 )
   [3] => Array ( [creditfeeid] => 321 [client] => Test 1 [adjustment] => 222.00 [issuedate] => 2012-02-10 00:00:00 [isrecurring] => No [comment] => 111 [commission] => 2.22 )
   [4] => Array ( [creditfeeid] => 292 [client] => Test 1 [adjustment] => 555.00 [issuedate] => 2012-01-25 13:04:43 [isrecurring] => Yes [comment] => 555 [commission] => 5.00 )
   [5] => Array ( [creditfeeid] => 317 [client] => Test 2 [adjustment] => 666.00 [issuedate] => 2012-02-10 00:00:00 [isrecurring] => No [comment] => 666 [commission] => 39.96 )
)

['comment'] 内の重複を削除しようとしています。

444 333 111 111 555 666

私は unique_array を使用してきましたが、うまくいかないようです。これは私が試したことです....

foreach($array as $row){
if(array_unique($row['comment'])){
    continue;
}else{
    echo $row['comment'] . "<br/>";
}
}

また

$array = array_unique($array);

foreach($array as $row){

        echo $row['comment'] . "<br/>";
}

私は何を間違っていますか？array_unique は私の問題に対する答えではありませんか?

前もって感謝します、

array_uniqueはあなたの問題に対する答えではありません。代わりに、次のようなことを検討してください。

$new_array = Array();
foreach($old_array as $a) {
    if( !isset($new_array[$a['comment']]))
        $new_array[$a['comment']] = $a;
}
$new_array = array_values($new_array);
