最近開發(fā)需求中需要輸出一個日歷,由于該日歷和數(shù)據(jù)庫中的數(shù)據(jù)扯有太多關(guān)系。于是沒有選擇比較常見的用js生成的日歷,而是用php輸出了一個日歷表格。ok,下面將如何用php輸出日歷的程序和大家分享一下。
php輸出的日歷效果如下圖:
具體代碼如下:
<p><?php</p>/*<br />* php 輸出日歷程序<br />*/ <br />header("Content-type: text/html;charset=utf-8");<br />$year=(!isset($_GET['year'])||$_GET['year']=="")?date("Y"):$_GET['year'];<br />$month=(!isset($_GET['month'])||$_GET['month']=="")?date("n"):$_GET['month'];<br />$curUrl=$_SERVER['PHP_SELF'];<br /><br />if($year<1971){<br /> echo "出錯!";<br /> echo "<BR>";<br /> echo "<a href=",$curUrl,">Back</a>";<br /> exit();<br />}<br />?> <br /><table width="200" border="1" cellspacing="0" cellpadding="0" bordercolor="#E7E7E7" style="font-size:12px;" align="center"> <br /><tr align="center"><td colspan="2"> <br /><?php <br />//<-------當(dāng)月份超出1至12時的處理;開始-------> <br />if($month<1){<br /> $month=12;<br /> $year-=1;<br />}<br />if($month>12){<br /> $month=1;<br /> $year+=1;<br />}<br />//<-------當(dāng)月份超出1至12時的處理;結(jié)束-------> <br />//<---------上一年,下一年,上月,下月的連接處理及輸出;開始---------> <br />echo "<a href=",$curUrl,"?year=".($year-1)."&month=".$month."><<</a>年<a href=",$curUrl,"?year=".($year+1)."&month=".$month.">>></a>";<br />?> <br /></td><td colspan="3"><?php echo $year."年".$month."月";?> <br /></td><td colspan="2"> <br /><?php <br />echo "<a href=",$curUrl,"?month=".($month-1)."&year=".$year."><<</a>月<a href=",$curUrl,"?month=".($month+1)."&year=".$year.">>></a>";<br />//<--------上一年,下一年,上月,下月的連接處理及輸出;結(jié)束---------> <br />?></td></tr> <br /><tr align=center><td><font color="red">日</font></td><td>一</td><td>二</td><td>三</td><td>四</td><td>五</td><td>六</td></tr><tr> <br /><?php <br />$d=date("d");<br />$FirstDay=date("w",mktime(0,0,0,$month,1,$year));//取得任何一個月的一號是星期幾,用于計算一號是由表格的第幾格開始<br />$bgtoday=date("d");<br />function font_color($month,$today,$year){//用于計算星期天的字體顏色<br /> $sunday=date("w",mktime(0,0,0,$month,$today,$year));<br /> if($sunday=="0"){<br /> $FontColor="red";<br /> }else{<br /> $FontColor="black";<br /> }<br /> return $FontColor;<br />}<br />function bgcolor($month,$bgtoday,$today_i,$year){//用于計算當(dāng)日的背景顏色<br /> $show_today=date("d",mktime(0,0,0,$month,$today_i,$year));<br /> $sys_today=date("d",mktime(0,0,0,$month,$bgtoday,$year));<br /> if($show_today==$sys_today){<br /> $bgcolor="bgcolor=#6699FF";<br /> }else{<br /> $bgcolor="";<br /> }<br /> return $bgcolor;<br />}<br />function font_style($month,$today,$year){//用于計算星期天的字體風(fēng)格<br /> $sunday=date("w",mktime(0,0,0,$month,$today,$year));<br /> if($sunday=="0"){<br /> $FontStyle="<strong>";<br /> }else{<br /> $Font;<br /> }<br /> return $FontStyle;<br />}<br />for($i=0;$i<=$FirstDay;$i++){//此for用于輸出某個月的一號位置<br /> for($i;$i<$FirstDay;$i++){<br /> echo "<td align=center> </td>\n";<br /> }<br /> if($i==$FirstDay){<br /> echo "<td align=center ".bgcolor($month,$bgtoday,1,$year)."><font color=".font_color($month,1,$year).">".font_style($month,1,$year)."1</font></td>\n";<br /> if($FirstDay==6){//判斷1號是否星期六<br /> echo "</tr>";<br /> }<br /> }<br />}<br />$countMonth=date("t",mktime(0,0,0,$month,1,$year));//某月的總天數(shù) <br />for($i=2;$i<=$countMonth;$i++){//輸出由1號定位,隨后2號直至月尾的所有號數(shù)<br /> echo "<td align=center ".bgcolor($month,$bgtoday,$i,$year)."><font color=".font_color($month,$i,$year).">".font_style($month,$i,$year)."$i</font></td>\n";<br /> if(date("w",mktime(0,0,0,$month,$i,$year))==6){//判斷該日是否星期六<br /> echo "</tr>\n";<br /> }<br />}<br />?> <br /></table>
