PHP simple calendar program code_PHP tutorial

PHP provides the date() function, which provides rich date processing functions. There are two data that need to be obtained now. The first is the total number of days in the month; the second is the day of the week where the first day of the month falls. The numbers represent 0 (indicating Sunday) to 6 (indicating Saturday).

The above data can be easily obtained through the date() function

The code is as follows

Copy code

 代码如下

复制代码

$month = $_GET['m']?$_GET['m']:date(‘n’);
$year = $_GET['y']?$_GET['y']:date(‘Y’);

$start_week = date(‘w’,mktime(0,0,0,$month,1,$year));
$day_num = date(‘t’,mktime(0,0,0,$month,1,$year));
$end = false;
?>

for($i = 0; $i<$start_week; $i++)
{
echo “”;
}

$j=1;

while($j<=$day_num)
{
echo “

”;
$week = ($start_week+$j-1)%7;

if($week ==6){
echo “nt

n”;
if($j != $day_num)
echo “tntt”;
else $end = true;
}
$j++;
}
while($week%7 != 6)
{
echo “”;
$week++;
}
if(!$end)
echo “n”;
?>

调用方法

 代码如下

代码如下	复制代码
$params = array(); if (isset($_GET['year']) && isset($_GET['month'])) { $params = array( 'year' => $_GET['year'],         'month' => $_GET['month'],     ); } $params['url']  = 'demo.php'; require_once 'calendar.class.php'; ?>                                                         $cal = new Calendar($params); $cal->display();             ?>

复制代码

$params = array();
if (isset($_GET['year']) && isset($_GET['month'])) {
    $params = array(
        'year' => $_GET['year'],
        'month' => $_GET['month'],
    );
}
$params['url']  = 'demo.php';
require_once 'calendar.class.php';
?>
