Build a monthly HTML calendar with php and the bash shell cal function.
This is a script that takes a monthly calendar produced by the Unix cal function, part of the BASH shell and found on all 'nix machines and Apples, and uses php to convert it into an HTML table calendar. The first part is the form, which I have on a separate index page. Then the part that goes at the top of the builder page. Then part that can go just about anywhere on the builder page. The texarea is there only for informational puposes and can be left off an 'operational' build.
<fieldset><form action="./builder.php" method="get">
<input type="hidden" name="mydata" id="mydata">
If you want a calender for this month, put nothing here: <input type="text" name="m-y" size=10 /><br>
<input type="submit" value="Load calendar"><br>
If you want a calender for a specific month in the past or future, for example July 1977, enter it this way: 7 1977, or 07 1977, just two numbers with a space.<br><br> To make a calender for this year just put in: -y.<br><br>To make a calender for a specific year, just put in the year: 1996, with no -y.<br><br>
Now the top of the builder.
$mnyr = $_GET['m-y'];
$cal = `cal $mnyr`;
$cal = `echo '$cal' | sed '/^$/d' `;
$cal = trim($cal);
The part that actually builds the calendar.
<textarea id="showcal" cols=21 rows=10 >
$cal_string = str_replace("\n","\n ",$cal);
$weeks = explode("\n",$cal_string);
$first_day = (strpos($weeks,"1")+1)/3;
$month = trim($weeks);
$find_last = trim($cal);
$size = strlen($find_last)-2;
$last_day = substr($find_last,$size);
echo "<table id=\"mytable\"><tr><caption class=\"Month\">".$month."</caption></tr><tr>\n";
echo "<th class=\"day\">Sunday</th>\n";
echo "<th class=\"day\">Monday</th>\n";
echo "<th class=\"day\">Tuesday</th>\n";
echo "<th class=\"day\">Wednesday</th>\n";
echo "<th class=\"day\">Thursday</th>\n";
echo "<th class=\"day\">Friday</th>\n";
echo "<th class=\"day\">Saturday</th>\n</tr><tr>\n";
$stack = count($weeks)-2;
for ( $i = 1 ; $i <= $stack*7 ; $i++ )
if ( $i < $first_day ) echo "<td class=\"dom\"></td>\n";
elseif ( $i > $first_day-1 && $i < $last_day+$first_day ) echo "<td class=\"dom\">".($i-$first_day+1 )."</td>\n";
else echo "<td class=\"dom\"></td>\n";
if ( $i%7 == 0 && $i < $stack*7 ) echo "</tr><tr>\n";
You may be able to omit the part with Sed.
