如何修复mb_strpos（）期望参数1为字符串，给定数组？

Question

我负责php artisan服务，总是出现错误

  

php工匠服务

In Str.php line 107:
mb_strpos() expects parameter 1 to be string, array given

当我编写更新时，总是会出现相同的错误。

In Str.php line 107:

  mb_strpos() expects parameter 1 to be string, array given


Script @php artisan package:discover --ansi handling the post-autoload-dump event returned with error code 1

当我在第107行打开 Str.php 文件时，就像这样。

 public static function contains($haystack, $needles)
    {
        foreach ((array) $needles as $needle) {
            if ($needle !== '' && mb_strpos($haystack, $needle) !== false) {
                return true;
            }
        }

        return false;
    }
