我如何重命名这个文件？
我有这个脚本，但我想重命名该文件：
<?php
$fieldname = $_REQUEST['fieldname'];
$uploaddir = 'uploads/';
$uploadfile = $uploaddir . basename($_FILES[$fieldname]['name']);
if (move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadfile)) {
//i want to rename the file before i can upload it
echo $uploadfile; // "success"
}
else {
echo "error";
}
?>
在将文件上传到 uploads/ 目录之前如何重命名该文件！

作为第二个参数传递给
move_uploaded_file的内容将用作文件名。What ever you pass as the 2nd parameter to
move_uploaded_filewill be used as the file name.move_uploaded_file函数正是这样做的。当您将上传的文件从临时位置移动到 uploads/ 目录时，您可以更改其名称。The
move_uploaded_filefunction does exactly that. When you are moving the uploaded file from the temporary location to the uploads/ directory, you can change the name of it.只需在
$uploadfile中指定不同的目标名称即可。Just specify a different target name in
$uploadfile.
