Question

上传文件后，我想通过将今天的日期追加到最后来重命名。

以下是将今天的日期放在文件的开头的示例：

move_uploaded_file($_FILES['imagefile']['tmp_name'], "docs/".$upload_date.$_FILES['imagefile']['name']);

但是如果我尝试将它添加到最后，它会在文件的扩展名后添加例如“testdoc.pdf2014-05-29”

但我想： “testdoc 2014-05-29.pdf”

如何在文件名和扩展名之间插入今天的日期（或任何变量）？

Answer 1

试试这个：

//split file name with "."
$fileName = explode(".", $_FILES['imagefile']['name']);

//remove extension from file name and save it in variable
$extension = array_pop($fileName);

//join back the array without extension
$fileName = implode(".", $fileName);

//get new file name by appending upload date and extension
$newFileName = $fileName . ' ' . $upload_date . '.' . $extension;

move_uploaded_file($_FILES['imagefile']['tmp_name'], "docs/".$newFileName);

你可以通过pathinfo阅读它来实现同样的目的并自己尝试。

Answer 2

$pathParts = pathinfo($_FILES['imagefile']['name']);
$fileNameExtension = $pathParts['extension'];

move_uploaded_file($_FILES['imagefile']['tmp_name'], "docs/" . $pathParts['filename'] . ' ' . $upload_date . '.' . $fileNameExtension);
