如何更改图像名称，并在上传时将“ - ”替换为空格。

Question

我使用此代码

<form action="upload.php" method="post" enctype="multipart/form-data"> 
Select image to upload: 
<input type="file" name="fileToUpload" id="fileToUpload"> 
<input type="submit" value="Upload Image" name="submit"> 
</form> 

PHP上传图片用PHP：

<?php 
$target_dir = "uploads/"; 
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 
$uploadOk = 1; 
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION); 



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

我想：如果我上传了一个名为“新York.jpg”的形象，名称被改为“新York.jpg”

Answer 1

在你的代码，在这里：

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 

地址：

$target_file = str_replace(' ', '-', $target_file); 

Answer 2

更换

$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]); 

与此2号线，

$target_filename = str_replace(' ', '_', basename($_FILES["fileToUpload"]["name"])); 
$target_file = $target_dir . $target_filename;
