Question

下面我有两个带数值的数组。

数组1 - 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 
)

数组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 }?>

我的预期输出数组3

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. 
    )

我想显示字符串，如果它不在数组中（reorder_str）。我试过这样但是它没有用完。我的数组3应该存储来自两个数组的Uncommon字符串，而new show没有任何空值或未定义的值。提前谢谢。同时我尝试使用array_diff，in_array，但我无法得到确切的答案。 / p>

根据您的预期输出检查此代码，

$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);

这是有效的link

使用PHP
