How can the last entry in a text file be retrieved using PHP?

To retrieve the last entry in a text file using PHP, you can read the entire file into an array using the `file()` function, then access the last element of the array to get the last entry. Another approach is to use the `file_get_contents()` function to read the entire file as a string, then split the string by new lines and get the last entry.

// Read the entire file into an array and get the last entry
$lines = file('your_file.txt');
$lastEntry = end($lines);

// Alternatively, read the file contents as a string and get the last entry
$fileContents = file_get_contents('your_file.txt');
$lines = explode("\n", $fileContents);
$lastEntry = end($lines);

// Output the last entry
echo $lastEntry;
