It is quite straightforward... Here's an example: <?php $year = strftime('%Y'); $month = strftime('%m'); $day = strftime('%d'); $weekDay = mcal_day_of_week($year, $month, $day); switch ($weekDay) { case 0: print("Today is Sunday"); break; case 1: print("Today is Monday"); break; ... case 6: print("Today is Saturday"); break; } // end switch ?> ssimon
If you don't have mcal, and need a replacement, here is an even easier way: <?php $utime = mktime (1,1,1,$month,$day,$year); $weekday=date('w',$utime); // 0 for Sunday through 6 for Saturday, just like mcal_day_of_week ?> cigalcohol
I don't have the MCAL lib, so I wrote a script that will return the day of the week for any date 2000+ using Zeller's Rule: http://mathforum.org/dr.math/faq/faq.calendar.html I only needed it to work for this century, so I replaced a few variables with constants, and I split up the equation itself into its component parts because I'm something of a n00b and I get condused easily. $y needs to be two digits, not four, eg, "02", "13", vs 2002, 2013, &c. <? if ( $m >= "3") { $mn = $m - 2; } else { $mn = $m + 10; } if ( $mn >= "11" ) { $yn = $y - 1; } else { $yn = $y; } $rem = $d; $rem = floor((13*$mn-1)/5) + $rem; $rem = $rem + $yn; $rem = floor($yn/4) + $rem; $rem = $rem - 35; $rem = $rem % 7; if ($rem < 0) { $rem = $rem + 7;} if ($rem == "0") { $w = "Sun"; } elseif ($rem == "1") { $w = "Mon"; } elseif ($rem == "2") { $w = "Tue"; } elseif ($rem == "3") { $w = "Wed"; } elseif ($rem == "4") { $w = "Thu"; } elseif ($rem == "5") { $w = "Fri"; } elseif ($rem == "6") { $w = "Sat"; } echo "$m.$d.$y is a $w"; ?> mail
I did it much easier (without "mcal" library): function convertday($n){ switch ($n){ case "Mon": return "Monday";break; case "Tue": return "Tuesday";break; case "Wed": return "Wednesday";break; case "Thu": return "Thursday";break; case "Fri": return "Friday";break; case "Sat": return "Saturday";break; case "Sun": return "Sunday";break; }; }; function curdate(){ $ret=date("d-m-Y").", ".convertday(date("D")); return $ret; }; |
