Date palindrome

Filed Under Affari miei | Leave a Comment

Oggi e’ un giorno palindromo (la data si puo’ leggere indifferentemente da sx verso dx e viceversa); ho fatto un semplice script in PHP che visualizza le date palindrome del 21. secolo…

<?php
$dt_da=mktime(0,0,0,1,1,2000);
$dt_a=mktime(0,0,0,12,31,2037);

while($dt_da<=$dt_a)
{
$dt=date(”dmY”,$dt_da);
if($dt==strrev($dt)) {
print “<br>”.$dt.” e’ palindromo!!”;
}
$tomorrow=mktime(0,0,0,date(”m”,$dt_da),date(”d”,$dt_da)+1,date(”Y”,$dt_da));
$dt_da=$tomorrow;
}
?>

l’output e’ il seguente:
10022001 e’ palindromo!!
20022002 e’ palindromo!!
01022010 e’ palindromo!!
11022011 e’ palindromo!!
21022012 e’ palindromo!!
02022020 e’ palindromo!!
12022021 e’ palindromo!!
22022022 e’ palindromo!!
03022030 e’ palindromo!!
13022031 e’ palindromo!!
23022032 e’ palindromo!!
