Note: you must have calendar support enabled on php for this to work. you can check this with phpinfo();This tutorial was last edited Sunday 19th February
Making a calendar in PHP is quite simple, you just need the right logic.
We'll start off with declaring our variables and starting off the function.
| function createCalendar() { $calendar = "CAL_GREGORIAN"; // Sets the "int" argument for the calendar functions. $year = date("Y"); // This year $unix = time(); // Now $today = unixtojd($unix); // Converts into Julian $today = cal_from_jd($today, CAL_GREGORIAN); // Converts into normal (i.e. weekday) |
The comments should help you out. Now that we've done that, we're going to start the output.
| echo "<table cellpadding="3" cellspacing="0">"; echo "<tr><td class="headdate" colspan="33" align="left"><b>Welcome, {$_SERVER['REMOTE_ADDR']}. | Today is ".$today[date]."</b></th></td>"; |
And now we finish off the output:
| $months = array( "January" => 1, "February" => 2, "March" => 3, "April" => 4, "May" => 5, "June" => 6, "July" => 7, "August" => 8, "September" => 9, "October" => 10, "November" => 11, "December" => 12 ); // Sets up the months into an associative array. $r = 0; foreach($months as $key => $value) { $days_in_month = cal_days_in_month(CAL_GREGORIAN,$value,$year); // How many days there are in the month echo "<tr style=""; // The next few lines are simply for aesthetics. if($key==date("F")) { echo " background: #239487;"; } echo "cursor: default;""; if($r==1) { echo " bgcolor="#CFCFCF""; $r = 0; } else { $r++; } echo "><th><b>$key $year</b></th>n<td>"; for($i=0;$i<$days_in_month;$i++) { $week_number = date("Week W",mktime(0, 0, 0, $value, ($i+1), $year)); // Finds out the week of the year $weekday = date("l",mktime(0, 0, 0, $value, ($i+1), $year)); // What weekday it is today echo "<td title="$week_number: $weekday"><a href="?">"; if($weekday==date("l") & & $i == (date("j")-1)) { echo "<!-- This is today -->"; } if($weekday=="Saturday"||$weekday=="Sunday") { // Is it a weekend? echo "<b>".($i+1)."</b> "; } else { echo ($i+1)."</a></td>n"; } } } echo "</td></tr>"; echo "</table>"; } |
The full function:
| function createCalendar() { $calendar = "CAL_GREGORIAN"; // Sets the "int" argument for the calendar functions. $year = date("Y"); // This year $unix = time(); // Now $today = unixtojd($unix); // Converts into Julian $today = cal_from_jd($today, CAL_GREGORIAN); // Converts into normal (i.e. weekday) echo "<table cellpadding="3" cellspacing="0">"; echo "<tr><td class="headdate" colspan="33" align="left"><b>Welcome, {$_SERVER['REMOTE_ADDR']}. | Today is ".$today[date]."</b></th></td>"; $months = array( "January" => 1, "February" => 2, "March" => 3, "April" => 4, "May" => 5, "June" => 6, "July" => 7, "August" => 8, "September" => 9, "October" => 10, "November" => 11, "December" => 12 ); // Sets up the months into an associative array. $r = 0; foreach($months as $key => $value) { $days_in_month = cal_days_in_month(CAL_GREGORIAN,$value,$year); // How many days there are in the month echo "<tr style=""; // The next few lines are simply for aesthetics. if($key==date("F")) { echo " background: #239487;"; } echo "cursor: default;""; if($r==1) { echo " bgcolor="#CFCFCF""; $r = 0; } else { $r++; } echo "><th><b>$key $year</b></th>n<td>"; for($i=0;$i<$days_in_month;$i++) { $week_number = date("Week W",mktime(0, 0, 0, $value, ($i+1), $year)); // Finds out the week of the year $weekday = date("l",mktime(0, 0, 0, $value, ($i+1), $year)); // What weekday it is today echo "<td title="$week_number: $weekday"><a href="?">"; if($weekday==date("l") & & $i == (date("j")-1)) { echo "<!-- This is today -->"; } if($weekday=="Saturday"||$weekday=="Sunday") { // Is it a weekend? echo "<b>".($i+1)."</b> "; } else { echo ($i+1)."</a></td>n"; } } } echo "</td></tr>"; echo "</table>"; } |
