未定义的数组键；尝试访问类型为null的值的数组偏移；foreach()参数必须是类型数组的{##**$}

Question

我什么都试过了有人能帮我吗？I‘s有3个错误:foreach().

PHP: 8.0 MYSQL: 5.1

​

foreach($_FILES["userfile"]["tmp_name"] as $key=>$tmp_name) {
    $file_name=$_FILES["userfile"]["name"][$key];
    $pasta_dir = "../www/layout/diario_de_obra/upload_img/";
    $diretorio_img = $pasta_dir . $file_name;
    $arquivo = $_FILES["userfile"]['tmp_name'][$key];
    move_uploaded_file($arquivo, $diretorio_img);
    print($file_name." enviado com sucesso!");
}



<div enctype="multipart/form-data">  <!-- action="upload" method="post"  accept=”image/* class="simagem" -->
     <label>Selecione as fotos de hoje aqui:
        <input id="image-file" type="file" name="userfile[]">
        <input id="image-file" type="file" name="userfile[]">
     </label>
</div>

在玩了你的例子之后，我想出了这个

<form action="imageUpload.php" method="post" enctype="multipart/form-data">
    <div>  <!-- action="upload" method="post"  accept=”image/* class="simagem" -->
        <label>Selecione as fotos de hoje aqui:
            <input id="image-file" type="file" name="userfile[]">
            <input id="image-file" type="file" name="userfile[]">
        </label>
    </div>
    <button type="submit">click me</button>
</form>

现在您的PHP开始工作了。
