PHP经典项目案例-(一)博客管理系统3
本篇给出首页左侧导航栏及右部公告区的实现。
六、左侧导航栏:
1、日历:
这里单独一个php文件,在显示日历的那个地方直接引用该文件即可:
cale.php
<?php class calendar{ private $year,$month,$day; private $week=array("Sun","Mon","Tue","Wed","Thu","Fri","Sat"); private $_month=array( "01"=>"一月", "02"=>"二月", "03"=>"三月", "04"=>"四月", "05"=>"五月", "06"=>"六月", "07"=>"七月", "08"=>"八月", "09"=>"九月", "10"=>"十月", "11"=>"十一月", "12"=>"十二月" ); function setyear($year){ //设置年份 $this->year=$year; } function getyear(){ //获得年份 return $this->year; } function setmonth($month){ //设置月份 $this->month=$month; } function getmonth(){ //获得月份 return $this->month; } function setday($day){ //设置日期 $this->day=$day; } function getday(){ //获得日期 return $this->day; } function OUT(){ //输出日历 $this->_env(); //设置显示的日期 $week=$this->getweek($this->year,$this->month,$this->day); //获得日期为星期几 $fweek=$this->getweek($this->year,$this->month,1); //获得此月第一天为星期几 echo "<div style="width:255;font:9pt"> <form action="%24_SERVER%5BPHP_SELF%5D" method="'post'" style="'margin:0'"> <select name="'month'" onchange="'this.form.submit();'">"; for($ttmpa=1;$ttmpamonth)==0){ $select="selected style='background-color:#FAFDE2'"; }else{ $select=""; } echo "<option value="'$ttmpb'">".$this->_month[$ttmpb]."</option>"; } echo " </select> <select name="'year'" onchange="'this.form.submit();'">"; //输出年份,前后10年 for($ctmpa=$this->year-10;$ctmpayear+10;$ctmpa++){ if($ctmpa>2050){ break; } if($ctmpayear)==0){ $select="selected style='background-color:#FAFDE2'"; }else{ $select=""; } echo "<option value="'$ctmpa'">$ctmpa</option>"; } echo "</select> </form> <br> <table border="0" align="center">"; for($Tmpa=0;$Tmpa<count>week);$Tmpa++){ //输出星期的标头 echo "<td>".$this->week[$Tmpa]."</td>"; } for($tmpb=1;$tmpbmonth,$this->day,$this->year));$tmpb++){ //输出所有日期 if(strcmp($tmpb,$this->day)==0){ //获得当前日期,并采用特色颜色做为标记 $flag=" bgcolor='#FF3366'"; }else{ $flag=' bgcolor=#FAFDE2'; } if($tmpb==1){ echo "<tr>"; for($tmpc=0;$tmpc"; } } if(strcmp($this->getweek($this->year,$this->month,$tmpb),0)==0){ //如果是周日 echo "</tr> <tr> <td align="'center'">$tmpb</td>"; }else{ echo "<td align="'center'">$tmpb</td>"; } } echo "</tr></count> </table> </div>"; } //获得方法内指定的日期的星期数 function getweek($year,$month,$day){ $week=date("w",mktime(0,0,0,$month,$day,$year)); //获得星期 return $week; //获得星期 } function _env(){ if(isset($_POST["month"])){ $month=$_POST["month"]; }else{ $month=date("m"); //默认为本月 } if(isset($_POST["year"])){ $year=$_POST["year"]; }else{ $year=date("Y"); //默认为本年 } $this->setyear($year); $this->setmonth($month); $date=sprintf('%1d',date('d')); $this->setday($date); }} $D=new calendar; $D->OUT(); ?>
在index.php里面直接引用该文件
<!-- 日历显示 --> <tr> <span style="white-space:pre"> </span><td height="155" align="center" valign="top"><?php include 'cale.php';?></td> </tr>
2、最新文章显示:
<!-- 最新文章显示 --><tr> <span style="white-space:pre"> </span><td height="125" align="center" valign="top"> <table width="200" border="0" cellpadding="0" cellspacing="0"> <tr> <span style="white-space:pre"> </span><td> <table width="201" border="0" cellpadding="0" cellspacing="0" style="margin-top:25px" valign="top"> </table> </td> </tr> <?php $sql="select id,title from tb_article order by id desc limit 5"; $res = $sqlHelper->execute_dql($sql); $i=1; while($info=$res->fetch_assoc()){ ?> <tr> <span style="white-space:pre"> </span><td width="201" align="left" valign="top"> <a href="article.php?file_id=<?php%20echo%20%24info%5B'id'%5D;?>" target="_blank"><font size="2"><?php echo $i."、".substr($info['title'],0,27);?></font></a> </td> </tr> <?php $i=$i+1; } ?> <tr> <td height="10" align="right"><a href="file_more.php"><img src="images/more.gif" style="max-width:90%" style="max-width:90%" border="0" alt="PHP经典项目案例-(1)博客管理系统3" > </a></td> </tr> </table> </td> </tr>
这里给出上面用到的方法实现代码:
sqlHelper.class.php部分代码:
class SqlHelper{ public $mysqli; public $dbname="db_tmlog"; public $username="root"; public $password="root"; public $host="localhost"; public function __construct(){ $this->mysqli = new mysqli($this->host, $this->username, $this->password, $this->dbname); if($this->mysqli->connect_error){ die("连接失败".$this->mysqli->connect_error); } $this->mysqli->query("set names utf8"); } //执行dql语句 public function execute_dql($sql){ $res = $this->mysqli->query($sql) or die($this->mysqli->error); //这里返回的是一个结果集,当调用$row = $res->fetch_assoc()时是一条一条的向下走,应该使用while循环 return $res; } <span style="font-family: Arial, Helvetica, sans-serif;">}</span>
dql语句就是简单的查询语句。
在使用数据库查询之前,先把这个文件包进去,然后new一个工具类对象,然后使用对象调用里面的函数。
3、最新图片显示
<!-- 最新图片显示 --><tr> <span style="white-space:pre"> </span><td height="201" align="center" valign="top"> <br> <table width="145" border="0" cellspacing="0" cellpadding="0"> <tr> <span style="white-space:pre"> </span><td> <table width="201" border="0" cellspacing="0" cellpadding="0" valign="top" style="margin-top:5px;"> <?php <span style="white-space:pre"> $sql="select id,tpmc,file from tb_tpsc order by id desc limit 2"; $res2 = $sqlHelper->execute_dql($sql); while($info=$res2->fetch_assoc()){ <span style="white-space:pre"> </span>$query="select * from tb_tpsc where id=".$info['id']; <span style="white-space:pre"> </span>$result=$sqlHelper->execute_dql($query); <span style="white-space:pre"> </span>if($row = $result->fetch_assoc()){ <span style="white-space:pre"> </span>$data = $row['file']; <span style="white-space:pre"> </span>} ?> <tr> <span style="white-space:pre"> </span><td width="9" rowspan="2" align="center"> </td> <td width="147" align="center"> <a href="image.php?recid=<?php%20echo%20%24info%5B'id'%5D;%20?>" target="_blank"> <img src="<?php%20echo%20%24data;?>" style="max-width:90%" style="max-width:90%" border="0" alt="PHP经典项目案例-(1)博客管理系统3" > </a> </td> <td width="10" rowspan="2" align="center"> </td> </tr> <tr> <td align="center">图片名称:<?php echo $info['tpmc'];?> </td> </tr> <?php } ?> <tr> <span style="white-space:pre"> </span><td colspan="3" height="10" align="right"><a href="pic_more.php"><img src="images/more.gif" style="max-width:90%" style="max-width:90%" border="0" alt="PHP经典项目案例-(1)博客管理系统3" > </a></td> </tr> </table> </td> </tr> </table> </td> </tr>
同样使用了数据库查询。
4、公告区实现
在公告区使用了我以前没有见过的一个标签
它里面设置了一些属性,就是当鼠标停留在上面的时候它就停止滚动,离开的时候就开始滚动。
<?php <span style="white-space:pre"> $p_sql = "select * from tb_public order by id desc"; $p_rst = $sqlHelper->execute_dql($p_sql);?><marquee onmouseover="this.stop()" style="width:426px; height:280px" onmouseout="this.start()" scrollamount="2" scrolldelay="7" direction="up" align=""><span style="FONT-SIZE: 9pt"><center> <?php <span style="white-space:pre"> </center></span>while($p_row = $p_rst->fetch_row()){?><a href="#" onclick="wopen=open('show_pub.php?id=<?php echo $p_row[0]; ?>','','height=200,width=1000,scollbars=no')"><?php echo $p_row[1]; ?></a><br> <?php }?></marquee>
到这里我们的首页基本就实现了。这是index.php 的完整代码:index.php提取码:iu09

Part 1: Initial Troubleshooting Steps Checking Apple’s System Status: Before delving into complex solutions, let’s start with the basics. The problem may not lie with your device; Apple's servers may be down. Visit Apple's System Status page to see if the AppStore is working properly. If there's a problem, all you can do is wait for Apple to fix it. Check your internet connection: Make sure you have a stable internet connection as the "Unable to connect to AppStore" issue can sometimes be attributed to a poor connection.

The differences are: 1. div is a block-level element, and span is an inline element; 2. div will automatically occupy a line, while span will not automatically wrap; 3. div is used to wrap larger structures and layouts, and span is used to wrap Text or other inline elements; 4. div can contain other block-level elements and inline elements, and span can contain other inline elements.

A colleague got stuck due to a bug pointed by this. Vue2’s this pointing problem caused an arrow function to be used, resulting in the inability to get the corresponding props. He didn't know it when I introduced it to him, and then I deliberately looked at the front-end communication group. So far, at least 70% of front-end programmers still don't understand it. Today I will share with you this link. If everything is wrong If you haven’t learned it yet, please give me a big mouth.

This article will help you interpret the vue source code and introduce why you can use this to access properties in various options in Vue2. I hope it will be helpful to everyone!

Watch4pro and gt each have different features and applicable scenarios. If you focus on comprehensive functions, high performance and stylish appearance, and are willing to bear a higher price, then Watch 4 Pro may be more suitable. If you don’t have high functional requirements and pay more attention to battery life and reasonable price, then the GT series may be more suitable. The final choice should be decided based on personal needs, budget and preferences. It is recommended to carefully consider your own needs before purchasing and refer to the reviews and comparisons of various products to make a more informed choice.
