What are some potential solutions or workarounds for the issue of being unable to access file date and time information on a web server using PHP?
The issue of being unable to access file date and time information on a web server using PHP can be solved by using the `filemtime()` function to retrieve the last modified time of a file. This function returns a Unix timestamp, which can be formatted using the `date()` function to display the date and time in a human-readable format.
$filename = 'example.txt';
$lastModified = filemtime($filename);
echo "Last modified: " . date("F d Y H:i:s.", $lastModified);
