linux php

Environment: CentOS6.5
Use php to get the modification time of the file. The result is 1970. Why is this?
Code:

<code>$handler=opendir(dirname(__FILE__)."/uploadfiles/down");
while($file=readdir($handler)){
    if($file=="." || $file==".."){
        continue;
    }
    echo $file.'-'.date('Y-m-d H:i:s',filectime($file)).'<br/>';
}</code>
Copy after login
Copy after login

Result:

linux - php uses the filectime function to get the modification time of the file and returns 1970

But the time of . and .. is normal, I don’t understand

Thank you everyone

Use filemtime() to get the last modification time of the file content. The filectime() you use is used to get the last inode modification time of the file.
