は2つの配列を比較して、私は値を持つ2つの配列を持って下にPHP

Question

を使用して新しい配列では珍しい文字列を格納します。私はそれが配列内に存在しない場合は、文字列を表示したいreorder_str

Array ( 
    [0] => A aacomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
    [1] => A eecomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
    [2] => defined 
    [3] => defined 
    [4] => defined 
) 

アレイ2 -reorder1

Array ( 
    [0] => A bbcomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
    [1] => A cccomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
    [2] => A aacomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
    [3] => A ddcomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
    [4] => A eecomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
) 

<?php if(in_array($reorder1[0], $reorder_str)){ 
?> 
    <div class="qitem di"> 
     1.<?php echo $reorder1[0];?> 
    </div> 
    <?php }?> 

私の予想出力ARRAY3

Array ( 
     [0] => A bbcomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
     [1] => A cccomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
     [2] => A ddcomputational agent is considered intelligent if it can adapt its actions to a particular setting. 
    )

アレイ1 （reorder_str）。私はこのように試みたが、うまくいかない。 私の配列3は、2つの配列からアンコモン文字列を格納する必要がありますし、新しいショーは、私がarray_diff、in_arrayで試してみましたadvance.Meanwhileの空または未定義value.Thanksを持っていないが、私は正確な答えを得ることができませんでした。あなたの予想出力あたりとして

チェックこのコードを、ここで

$arr1 = array(
    0 => "A aacomputational agent is considered intelligent if it can adapt its actions to a particular setting.", 
    1 => "A eecomputational agent is considered intelligent if it can adapt its actions to a particular setting.", 
    2 => "defined ", 
    3 => "defined ", 
    4 => "defined ", 
); 
$arr1 = array_map('trim', $arr1); 
$arr2 = array(
    "0" => "A bbcomputational agent is considered intelligent if it can adapt its actions to a particular setting.", 
    "1" => "A cccomputational agent is considered intelligent if it can adapt its actions to a particular setting.", 
    "2" => "A aacomputational agent is considered intelligent if it can adapt its actions to a particular setting.", 
    "3" => "A ddcomputational agent is considered intelligent if it can adapt its actions to a particular setting.", 
    "4" => "A eecomputational agent is considered intelligent if it can adapt its actions to a particular setting." 
); 
$arr2 = array_map('trim', $arr2); 
$result = array_diff($arr2,$arr1); 
print_r($result);
