Answer 1

使用as suggested in this SO answer函数的解决方案：

$arr = ['users' => ['name' => 'ASSOCIATION OF�CHIEFS OF USERS']];
$arr['users']['name'] = preg_replace("/[^\w [:punct:]]+/i", " ", $arr['users']['name']);

print_r($arr);

输出：

Array
(
    [users] => Array
        (
            [name] => ASSOCIATION OF CHIEFS OF USERS
        )
)

Answer 2

只需使用str_replace()

即可

echo str_replace ("�", " ", "ASSOCIATION OF�CHIEFS OF USERS");

Answer 3

试试这个，

$str = "ASSOCIATION OF�CHIEFS OF USERS"; // your $arr['users']['name'];
echo preg_replace("/[^a-zA-Z0-9\s]/", "", $str);

OR

$arr['users']['name'] = preg_replace("/[^a-zA-Z0-9\s]/", "", $arr['users']['name']);

它会删除所有字符，但字母，数字和空格。

尝试一下，它会起作用。
