如果數組包含另一個數組中的字符串，則刪除

Question

因此，我們的想法是從一個數組中刪除其他數組的編號列表，但僅刪除第一個數組，解決該問題的任何幫助將不勝感激。

$my_array = array("Sandra Loor,593984076233","Adrian,593998016010","Lucas,593999843424");


function myFilter($string) {
    $to_remove = array("593984076233","593998016010");
    foreach($to_remove as $remove)  {
        return strpos($string, $remove) === false;
    }

}

$newArray = array_filter($my_array, 'myFilter');

foreach ($newArray as $val){
    echo $val.'<br>';
}

Answer 1

問題是您的過濾器將始終從循環的第一次迭代return 。 相反，如果找到條目，它將返回false，並且在循環結束時將返回true（即完全找不到）...

function myFilter($string) {
    $to_remove = array("593984076233","593998016010");
    foreach($to_remove as $remove)  {
        if ( strpos($string, $remove) !== false )
            return false;
    }
    return true;
}

另一種方法是使用preg_grep在數組中搜索要刪除的項目，然后使用array_diff刪除它們。

$my_array = array("Sandra Loor,593984076233","Adrian,593998016010","Lucas,593999843424");
$to_remove = array("593984076233","593998016010");

$to_remove = "/" . implode("|", $to_remove) . "/";
$match = preg_grep($to_remove, $my_array);
$filtered = array_diff($my_array, $match);

var_dump($filtered);
// Lucas,593999843424

您也可以將其捆扎成一個襯板，如下所示：

$my_array = array("Sandra Loor,593984076233","Adrian,593998016010","Lucas,593999843424");
$to_remove = array("593984076233","593998016010");

$filtered = array_diff($my_array, preg_grep("/" . implode("|", $to_remove) . "/", $my_array));

var_dump($filtered);
