使用PHP或Javascript重命名本地磁盘上的文件

<?php
$oldFileName = 'old_file.txt';
$newFileName = 'new_file.txt';

if (file_exists($oldFileName)) {
    if (rename($oldFileName, $newFileName)) {
        echo "文件重命名成功！";
    } else {
        echo "文件重命名失败！";
    }
} else {
    echo "文件不存在！";
}
?>

<script>
var oldFileName = 'old_file.txt';
var newFileName = 'new_file.txt';

fetch(oldFileName)
  .then(response => response.blob())
  .then(blob => {
    var url = URL.createObjectURL(blob);
    var a = document.createElement('a');
    a.href = url;
    a.download = newFileName;
    a.click();
    URL.revokeObjectURL(url);
    console.log("文件重命名成功！");
  })
  .catch(error => {
    console.log("文件重命名失败！");
  });
</script>
