PHP filemtime() | Get Last Modified Time/Date of a File
The PHP filemtime() function is used when we need to find the last time and date, when the file was modified. For example:
<?php echo "<p>The latest time when the file <b>codescracker.txt</b> was modified:</p>"; echo filemtime("codescracker.txt"); echo "<br>Or<br>"; echo date("d F, Y H:i:s", filemtime("codescracker.txt")); ?>
The output produced by above PHP example on filemtime() function is:
Since the filemtime() function returns the last modified time/date of the file, in Unix timestamp, that almost can not be understandable for normal user. Therefore, let me use the date() function to convert the time into a format that a normal user can understand.
<?php $file = "codescracker.txt"; echo "<p>The file, $file last modified on:</p>"; $mt = filemtime($file); if($mt) { echo "Time: " .date("H:i:s", $mt); echo "<br>"; echo "Date: " .date("d F, Y", $mt); } else echo "Unable to find time, when the file last modified!"; ?>
Now the output produced by above PHP example, should be:
PHP filemtime() Syntax
