Question

我正在尝试在上传时重命名文件，但它没有像我预期的那样重命名。只想添加名称的日期和时间。
附上以下代码。

if(isset($_FILES['img_ct_1'])){

$today = date("Ymd");

//prepare url
$temp_path = CDN_URL.'photos/';

$name_array = $_FILES['img_ct_1']['name'];
$tmp_name_array = $_FILES['img_ct_1']['tmp_name'];
$type_array = $_FILES['img_ct_1']['type'];
$size_array = $_FILES['img_ct_1']['size'];
$error_array = $_FILES['img_ct_1']['error'];
$upload_dir = $_SERVER['DOCUMENT_ROOT'].'/photos/';


for($i = 0; $i < count($tmp_name_array); $i++){
    if(move_uploaded_file($tmp_name_array[$i],$upload_dir.time().$name_array[$i])){
        print_r ($name_array[$i]);
        $array['path'] = $temp_path.$newfilename;
        $array['success'] = true ;
    } else {
        echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
    }
}
}

尝试这种方式：

for($i = 0; $i < count($tmp_name_array); $i++){
    $file = $today.time().$name_array[$i];
    if(move_uploaded_file($tmp_name_array[$i], $upload_dir . $file)){
        print_r ($name_array[$i]);
        $array['path'] = $temp_path.$newfilename;
        $array['success'] = true ;
    } else {
        echo "move_uploaded_file function failed for ".$name_array[$i]."<br>";
    }
}
