IF you are looking this output from a browser, you must use <br />tag or, put <pre>before your echo.

如果您正在从浏览器查看此输出，则必须使用<br />标记或放在<pre>您的回声之前。

For new line
example.

对于新行
示例。

if (file_exists($fName)) {
   echo "CreationTime: ".$CreationTime. "<br />".
        "CurrentTime: ".$CurrentTime. "<br />" .
        "after ".($fLifeTime)." Days from Creation: ".$fAge;
   }

pre example

前例

 if (file_exists($fName)) {
      echo "<pre>";
       echo "CreationTime: ".$CreationTime. PHP_EOL .
            "CurrentTime: ".$CurrentTime. PHP_EOL .
            "after ".($fLifeTime)." Days from Creation: ".$fAge;

Maybe try to use PHP_EOLand nl2br()?

也许尝试使用PHP_EOL和nl2br()？

if (!file_exists($fName)) {
    $info = "CreationTime: " . $CreationTime . PHP_EOL .
        "CurrentTime: ". $CurrentTime . PHP_EOL .
        "after ". ($fLifeTime)." Days from Creation: " . $fAge;

    echo nl2br($info);
}
