如何在上传图片时更改图片名称并用“-”代替 space。

Question

我正在使用此代码通过 PHP

上传图片

<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:

<?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.";
}
} 
?>

我想要这个：如果我上传一张名为 "New York.jpg" 的图片，名称会更改为 "New-York.jpg"

Answer 1

在您的代码中，此处：

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

添加：

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

Answer 2

替换

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

加上这两行，

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