利用PHP实现日历表

<?php

    header(content-type:"text/html;charset=utf-8");

    //设定变量假设1个月为31天

    $days=31;

    $k=0;

    echo "<table width='700px' border='1px' align='center'>";

    echo "<caption>日历表</caption>";

    for($i=1;$i<=$days;){

        //记录循环次数,隔行换色

        $k++;

        if($k%2==0){

            echo "<tr style='background:#ccc'>";

        }else{

            echo "<tr style='background:#faa'>";

        }

            for($j=1;$j<=7;$j++){

                if($i>$days){

                    echo "<td>&nbsp;</td>";

                }else{

                    echo "<td>{$i}</td>";

                }

                $i++;

            }

        echo "</tr>";

    }

    echo "</table>";
