Question

所以我有这个HTML文件上传表单，后端如下：

if(isset($_POST['two'])){
    $target_dir = "pageimg/";
    $target_file = $target_dir . basename($_FILES["image"]["name"]);
    $uploadOk = 0;
    $imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);

// Check if image file is a actual image or fake image

    $check = getimagesize($_FILES["image"]["tmp_name"]);
    if($check !== false) {
        $uploadOk = 0;
    } else {
        $uploadOk = 1;
    }

// Check if file already exists

if (file_exists($target_file)) {
    $uploadOk = 2;
}
// Check file size

if ($_FILES["image"]["size"] > 500000) {
    $uploadOk = 3;
}
// Allow certain file formats

if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 4;
}
// Check if $uploadOk is set to 0 by an error

if ($uploadOk == 5) {
    echo "Sorry, your file was not uploaded.";

// if everything is ok, try to upload file

} else {
    if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
        echo "The file ". basename( $_FILES["image"]["name"]). " has been uploaded.";
    } else {
        echo "Sorry, there was an error uploading your file.";
    }
}
}

这样可以正常工作并上传文件，但是，如果我上传FB Logo.png这样的文件，它会按照空格上传。我想编辑此脚本以关闭任何空格或重命名图像？我环顾四周，发现如何在当前脚本中实现任何脚本没有运气？这一切看起来有点像“这是代码”自己解决，我没有运气。我试过这个......

str_replace(" ", "_", $_FILES['image']['name']);

但不太确定我是否正确添加了它？图像无法在测试时上传。

另外，我怎么会回想起图像名称？我会用：

$_FILES['name'];

只是为了回忆图像名称？

从文件上传中删除空格？
