Do you need to find out in PHP, when a file was modified? Then you should take a look at the PHP-function filemtime. This function expects a filename as parameter and returns the modification-time of this file.
Here is an example:
< ?php echo filemtime('anyfile.html'); ?>
This PHP-script will output the timestamp of the last modification of the file anyfile.html.
You can also format this by using the date-function:
<?php // Gets modification time and formats it echo date("Y-m-d h:i:s",filemtime('anyfile.html')); ?>
And if you want to include this function in a php-file to display its last modification time, you could try something like this:
<?php /* 1. Uses basename() to get the filename from $_SERVER['PHP_SELF'] 2. Uses filemtime to get modification-time for this file 3. Uses date to format the time. */ echo date("Y-m-d h:i:s",filemtime(basename($_SERVER['PHP_SELF']))); ?>
Have fun 😉
