在表列中的php中回显月份的日期？

Question

ok i'm sorry this code is all such a mess, but i have created a table with html text area forms which acts as a type of calendar for users to mark when they will be doing what on which day. i have monday - sunday shown in my code below but have 4 weeks or 4 sets of monday-sunday's in the calendar in total.

I am wondering if i am able to use a php code to place the date of each month; i.e. 1st-31st into each row/column depending on which month it is at the time?

I'd really appreciate anyones help if they could show me how i can do this and i know it doesnt look a very good way of doing it but i do need to do it this way. Thanks

This will position your dates in the correct columns - just add whatever you need to the inner loop of printCalendar():

<?php
function getCalendarRows($year,$month)
{
    $result=array();
    $dt=new DateTime(sprintf('%04d-%02d-01',$year,$month));
    $weekDay=$dt->format('w'); //Weekday of the first
    $nextMonth=$month==12?1:$month+1;
    $nextMonthYear=$nextMonth==1?$year+1:$year;
    $dt=new DateTime(sprintf('%04d-%02d-01',$nextMonthYear,$nextMonth));
    $dt->sub(new DateInterval('P1D')); //last day of the month
    $row=array();
    $lastDay=$dt->format('j');
    //Start the first row with empty columns (false)
    for($i=0; $i<$weekDay; $i++)$row[]=false; 
    for($i=1; $i<=$lastDay; $i++)
    {
        $row[]=$i;
        $weekDay++;
        if($weekDay>6)
        {
            $result[]=$row;
            $row=array();
            $weekDay=0;
        }
    }
    if($weekDay>0) 
    {
        //Fill up the last row with empty columns
        for($i=$weekDay+1; $i<7; $i++) $row[]=false;
        $result[]=$row;
    }
    return $result;
}

function printCalendar($year,$month)
{
    $rows=getCalendarRows($year,$month);
    echo '
<table>
    <tr>
        <th>Sunday</th><th>Monday</th><th>Tuesday</th><th>Wednesday</th><th>Thursday</th><th>Friday</th><th>Saturday</th>
    </tr>';
    foreach($rows as $row)
    {
        echo '
    <tr>';
        foreach($row as $weekday=>$date)
        {
            echo '
        <td width="50px" height="50px">'.($date===false?'':$date).'</td>';
//Put whatever else you want in here, you have $year, $month, $date, and $weekday (0 to 6)
//NOTE - if $date===false, this is an empty column
        }
        echo '
    </tr>';
    }
    echo '
</table>';
}
echo '
<h1>Jan 2013</h1>';
printCalendar(2013,01);
echo '
<h1>Feb 2013</h1>';
printCalendar(2013,02);
echo '
<h1>Mar 2013</h1>';
printCalendar(2013,03);
echo '
<h1>Dec 2013</h1>';
printCalendar(2013,12);
?>
