当文件有空格时添加缩进(上传文件)

Question

我正在使用一个系统上传图像，文件...使用 PHP，我在将"-"放入有空格的文件中时遇到问题......我怎样才能放，以便我上传的所有图像都有空格，放一个缩进？( - )

我的代码：

<?php
$target_dir = "uploads/";
$target_file = $target_dir .  date('d_m_Y_H_i_s') . '_'. $_FILES["fileToUpload"]["name"];
if($target_file = null) {
echo"nada";
}
$uploadOk = 1;
$imageFileType = pathinfo($target_file, PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
}
// Check if file already exists
if (file_exists($target_file)) {
echo "Sorry, file already exists.";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
echo "";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ". basename( date('d_m_Y_H_i_s') . '_'. $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
?>

在我看来，使用str_replace将是最简单的方法。

$target_file = $target_dir . date('d_m_Y_H_i_s') . '_'. str_replace(' ','-',$_FILES["fileToUpload"]["name"]);
