Answer 1

允许从输入文件中选择multiple文件就像

<input type="file" name="image" multiple>

获取所有选定的文件

print_r($_FILES); // will return you detail of all files in array

Internet中不支持输入标记的multiple属性 Explorer 9及更早版本。

Answer 2

您可以一次选择多个文件，但需要添加多个文件，然后您可以选择这样的文件。

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Document</title>
</head>
<body>
    <form action="upload.php" method="post" multipart="" enctype="multipart/form-data">
        <input type="file" name="img[]" multiple>
        <input type="submit">
    </form>
</body>
</html>

<?php
echo '<pre>';
$img = $_FILES['img'];

if(!empty($img))
{
    $img_desc = reArrayFiles($img);
    print_r($img_desc);

    foreach($img_desc as $val)
    {
        $newname = date('YmdHis',time()).mt_rand().'.jpg';
        move_uploaded_file($val['tmp_name'],'./uploads/'.$newname);
    }
}

function reArrayFiles($file)
{
    $file_ary = array();
    $file_count = count($file['name']);
    $file_key = array_keys($file);

    for($i=0;$i<$file_count;$i++)
    {
        foreach($file_key as $val)
        {
            $file_ary[$i][$val] = $file[$val][$i];
        }
    }
    return $file_ary;
}
