What does this PHP script do?
This PHP script defines a function called GetCurrentSeason() that determines the current season based on the current date, following the seasonal pattern of the Northern Hemisphere . The result returned by GetCurrentSeason() can be used to dynamically select and display a background image corresponding to the current season — for example, an image labeled "spring.jpg" when it is springtime.
PHP
<?php
function GetCurrentSeason() {
// Approximate start dates for seasons in the Northern Hemisphere
$seasonDates = array(
'01-01' => 'winter',
'03-21' => 'spring',
'06-21' => 'summer',
'09-21' => 'autumn',
'12-21' => 'winter' // winter starts again
);
$currentYear = date("Y");
$currentTime = strtotime("now");
$currentSeason = 'winter'; // default fallback
foreach ($seasonDates as $date => $season) {
$seasonStart = strtotime("$currentYear-$date");
if ($currentTime >= $seasonStart) {
$currentSeason = $season;
}
}
return $currentSeason;
}
$returnCurrentSeason = GetCurrentSeason();
// echo "Current season: " . $returnCurrentSeason;
?>
