Jun 20, 2016 pm 01:04 PM

最近开发需求中需要输出一个日历,由于该日历和数据库中的数据扯有太多关系。于是没有选择比较常见的用js生成的日历,而是用php输出了一个日历表格。ok,下面将如何用php输出日历的程序和大家分享一下。

php输出的日历效果如下图:


具体代码如下:

<p><?php</p>/*<br />* php 输出日历程序<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($year<1971){<br />	echo "出错!";<br />	echo "<BR>";<br />	echo "<a href=",$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 />//<-------当月份超出1至12时的处理;开始-------> <br />if($month<1){<br />	$month=12;<br />	$year-=1;<br />}<br />if($month>12){<br />	$month=1;<br />	$year+=1;<br />}<br />//<-------当月份超出1至12时的处理;结束-------> <br />//<---------上一年,下一年,上月,下月的连接处理及输出;开始---------> <br />echo "<a href=",$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,下月的连接处理及输出;结束---------> <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));//取得任何一个月的一号是星期几,用于计算一号是由表格的第几格开始<br />$bgtoday=date("d");<br />function font_color($month,$today,$year){//用于计算星期天的字体颜色<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){//用于计算当日的背景颜色<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){//用于计算星期天的字体风格<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;$i++){//此for用于输出某个月的一号位置<br />	for($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($FirstDay==6){//判断1号是否星期六<br />			echo "</tr>";<br />		}<br />	}<br />}<br />$countMonth=date("t",mktime(0,0,0,$month,1,$year));//某月的总天数 <br />for($i=2;$i<=$countMonth;$i++){//输出由1号定位,随后2号直至月尾的所有号数<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){//判断该日是否星期六<br />		echo "</tr>\n";<br />	}<br />}<br />?> <br /></table>

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
