如何更改圖像名稱，並在上傳時將「 - 」替換爲空格。

Question

我使用此代碼

<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上傳圖片用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：如果我上傳了一個名爲「新York.jpg」的形象，名稱被改爲「新York.jpg」

Answer 1

在你的代碼，在這裏：

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

地址：

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

Answer 2

更換

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

與此2號線，

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