30. Last Modification Time of Current Page

Write a PHP script to get the time of the last modification of the current page.

Sample Solution:

PHP Code:

<?php
// Get the last modification time of the current script using getlastmod()
$last_modified_time = getlastmod();
// Format the last modification time and print it
echo "Last modified: " . date("F d Y H:i:s.", $last_modified_time) . "\n";
?>

Explanation:

Get Last Modification Time:

The function getlastmod() retrieves the last modification time of the current script in Unix timestamp format.
The result is stored in the variable $last_modified_time.

Format the Last Modification Time:

The date("F d Y H:i:s.", $last_modified_time) function formats the timestamp into a human-readable string, specifying the format as:

F: Full textual representation of a month (e.g., January)
d: Day of the month (with leading zeros)
Y: Four-digit year
H: Hour (24-hour format)
i: Minutes
s: Seconds

Output Last Modified Time:

The echo statement outputs the formatted last modification time, prefixed by the string "Last modified: ", followed by a newline (\n).

Output:

Last modified: June 26 2017 16:52:16.

The result may varry for your system date and time.
