Fileatime()

What is the fileatime() Function?

The fileatime() function is a built-in PHP function that returns the last access time of a file. This function returns a Unix timestamp representing the time the file was last accessed.

Here's the basic syntax of the fileatime() function:

fileatime(filename);

Where filename is the name of the file to be checked.

How to Use the fileatime() Function?

Using the fileatime() function is straightforward. Here are the steps to follow:

1. Call the fileatime() function, passing in the name of the file you want to check.
2. The function will return a Unix timestamp representing the time the file was last accessed.
3. You can format the Unix timestamp using the date() function to display the time in a more human-readable format.

Here's an example code snippet that demonstrates how to use the fileatime() function:

<?php

$filename = 'myfile.txt';
$last_access_time = fileatime($filename);
$access_time_string = date('F d Y H:i:s.', $last_access_time);
echo "The file $filename was last accessed on $access_time_string";

In this example, we check when the file myfile.txt was last accessed using the fileatime() function. We store the Unix timestamp representing the last access time in the $last_access_time variable. We then format the Unix timestamp using the date() function and store it in the $access_time_string variable. Finally, we output a message indicating when the file was last accessed, using the formatted time string.
