I've searched around for calendars that is on PHP but all I searched are date time picker.
But what I only want is a simple calendar that shows me the date, without picking them.
I just need the calendar to display simply like how a normal calendar works in our Operating System, thanks.
Is there any way?

Firstly copy the source code below to a class file "calendar. php". We will go through each important function. This "Calendar" class is a complete object, which will echo a HTML calendar upon calling its "show()" function.
Here's one you can use: http://keithdevens.com/software/php_calendar
<?php
//http://keithdevens.com/software/php_calendar
$time = time();
$today = date('j', $time);
$days = array($today => array(null, null,'<div id="today">' . $today . '</div>'));
$pn = array('«' => date('n', $time) - 1, '»' => date('n', $time) + 1);
echo generate_calendar(date('Y', $time), date('n', $time), $days, 1, null, 0);
// PHP Calendar (version 2 . 3), written by Keith Devens
// http://keithdevens . com/software/php_calendar
// see example at http://keithdevens . com/weblog
// License: http://keithdevens . com/software/license
function generate_calendar($year, $month, $days = array(), $day_name_length = 3, $month_href = NULL, $first_day = 0, $pn = array())
{
$first_of_month = gmmktime(0, 0, 0, $month, 1, $year);
// remember that mktime will automatically correct if invalid dates are entered
// for instance, mktime(0,0,0,12,32,1997) will be the date for Jan 1, 1998
// this provides a built in "rounding" feature to generate_calendar()
$day_names = array(); //generate all the day names according to the current locale
for ($n = 0, $t = (3 + $first_day) * 86400; $n < 7; $n++, $t+=86400) //January 4, 1970 was a Sunday
$day_names[$n] = ucfirst(gmstrftime('%A', $t)); //%A means full textual day name
list($month, $year, $month_name, $weekday) = explode(',', gmstrftime('%m, %Y, %B, %w', $first_of_month));
$weekday = ($weekday + 7 - $first_day) % 7; //adjust for $first_day
$title = htmlentities(ucfirst($month_name)) . $year; //note that some locales don't capitalize month and day names
//Begin calendar . Uses a real <caption> . See http://diveintomark . org/archives/2002/07/03
@list($p, $pl) = each($pn); @list($n, $nl) = each($pn); //previous and next links, if applicable
if($p) $p = '<span class="calendar-prev">' . ($pl ? '<a href="' . htmlspecialchars($pl) . '">' . $p . '</a>' : $p) . '</span> ';
if($n) $n = ' <span class="calendar-next">' . ($nl ? '<a href="' . htmlspecialchars($nl) . '">' . $n . '</a>' : $n) . '</span>';
$calendar = "<div class=\"mini_calendar\">\n<table>" . "\n" .
'<caption class="calendar-month">' . $p . ($month_href ? '<a href="' . htmlspecialchars($month_href) . '">' . $title . '</a>' : $title) . $n . "</caption>\n<tr>";
if($day_name_length)
{ //if the day names should be shown ($day_name_length > 0)
//if day_name_length is >3, the full name of the day will be printed
foreach($day_names as $d)
$calendar .= '<th abbr="' . htmlentities($d) . '">' . htmlentities($day_name_length < 4 ? substr($d,0,$day_name_length) : $d) . '</th>';
$calendar .= "</tr>\n<tr>";
}
if($weekday > 0)
{
for ($i = 0; $i < $weekday; $i++)
{
$calendar .= '<td> </td>'; //initial 'empty' days
}
}
for($day = 1, $days_in_month = gmdate('t',$first_of_month); $day <= $days_in_month; $day++, $weekday++)
{
if($weekday == 7)
{
$weekday = 0; //start a new week
$calendar .= "</tr>\n<tr>";
}
if(isset($days[$day]) and is_array($days[$day]))
{
@list($link, $classes, $content) = $days[$day];
if(is_null($content)) $content = $day;
$calendar .= '<td' . ($classes ? ' class="' . htmlspecialchars($classes) . '">' : '>') .
($link ? '<a href="' . htmlspecialchars($link) . '">' . $content . '</a>' : $content) . '</td>';
}
else $calendar .= "<td>$day</td>";
}
if($weekday != 7) $calendar .= '<td id="emptydays" colspan="' . (7-$weekday) . '"> </td>'; //remaining "empty" days
return $calendar . "</tr>\n</table>\n</div>\n";
}
?>
It's a pretty basic mini calendar. No fancy functions.

I have written just one such with PHP5 + ajax(if you are need to use it):

public $show_month_selector = true;
public function __construct($atts = array()) {
if (isset($atts['first_day_of_week'])) {
$this->first_day_of_week = $atts['first_day_of_week'];

$this->current_year = date('Y');
