PHP - move_uploaded_file将空格替换为 %20

Question

>我正在使用move_uploaded_file上传文件，但是当我上传带有空格的文件时，它不会替换为%20，然后我卡在带有空格的文件名上，我该如何解决这个问题？

这是我的代码：

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["logoHeader"]["name"]);
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));

if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["logoHeader"]["tmp_name"]);
if($check === false) {
$error = 'File is not an image.';
include('views/logos/index.php');
break;
}
}
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif" ) {
$error = 'Sorry, only JPG, JPEG, PNG & GIF files are allowed.';
include('views/logos/index.php');
break;
}
if (move_uploaded_file($_FILES["logoHeader"]["tmp_name"], $target_file)) {
$error = 'Image has been uploaded.';
}
else
{
$error = 'Sorry, there was an error uploading your file.';
include('views/logos/index.php');
break;
}

Answer 1

$target_dir = "uploads/";
$target_file = $target_dir . basename($_FILES["logoHeader"]["name"]);
//new line
$target_file = checkName($target_file);
//end new line
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
//your code

并添加检查名称功能

function checkName($name){
if(preg_match("`^[-0-9A-Z_.]+$`i",$name)){
return $name;
}else{
$name = str_replace(' ', '%20', $name);
return $name;
}

但是您仍然无法幸免于其他"难以理解"的角色。如果文件的名称包含 URL 不允许的字符，您将如何提供该文件？ 例如：ÆÞΔΦÜЩЫž.jpg

尝试查找有关 URL 辅助信息域;)
