How can PHP be used to sort temperature values in an array obtained from a CSV file?

To sort temperature values in an array obtained from a CSV file using PHP, you can read the CSV file, extract the temperature values into an array, and then use the `sort()` function to sort the array in ascending order. This will allow you to easily organize the temperature values from lowest to highest. 

<?php

// Read the CSV file
$csvFile = 'temperatures.csv';
$csvData = array_map('str_getcsv', file($csvFile));

// Extract temperature values into an array
$temperatures = [];
foreach ($csvData as $data) {
    $temperatures[] = $data[1]; // Assuming temperature values are in the second column
}

// Sort the temperature values in ascending order
sort($temperatures);

// Display sorted temperature values
foreach ($temperatures as $temperature) {
    echo $temperature . " ";
}

?>
