How can PHP be used to read the last line of a CSV file and extract columns separately?

To read the last line of a CSV file and extract columns separately in PHP, you can use the `fgetcsv()` function to read the file line by line until reaching the last line. Then, you can explode the last line by the delimiter (usually a comma) to separate the columns. 

<?php
$filename = 'data.csv';
$file = fopen($filename, 'r');

$lastLine = '';
while (!feof($file)) {
    $lastLine = fgetcsv($file);
}

fclose($file);

$columns = explode(',', $lastLine[0]);
foreach ($columns as $column) {
    echo $column . PHP_EOL;
}
?>
