内容发错了,下边应该是分页的内容,想加个首页和尾页
<?php $pages=ceil($count/$list_num); echo "<table width=740 border=0 cellspacing=0 cellpadding=0 align=center class='text'> <tbody> <tr> <td width='190'><font color='#ff0000'>目前共有".$count."条记录</font> </td> <td width='205'>共".$pages."页</td>"; if($offset){ $preoffset=$offset-$list_num; print "<td width='170'><a href=\"?offset=$preoffset\">上一页</a></td>";} else { echo "<td width='170'>上一页</td>"; } $newoffset=$offset+$list_num; if(($pages!=0)&&(($newoffset/$list_num)!=$pages)) { print("<td width='170'><a href=\"?offset=$newoffset\">下一页</a></td>"); } else{ echo "<td width='170'>下一页</td>";} $pageno=($offset/$list_num)+1; echo "<td width='112' class=text>第<input class=text type='text' size='4'value=".$pageno." readonly>页</td> <td width='4'> </td></tr></table>"; ?>

居然两个print语句的写法不一样……唉,进步空间很大 关于尾页的问题我还想问一下,加入我的列表有6也,我加入了尾页的语句后,点“尾页”后,系统没有显示第6页的内容,而是只显示了一个列表头,并且在第()页处显示的是第(6.666667)页,这是怎么回事呢?
你的总页数也就是你的尾页数
你这里的总页数是$pages,那么尾页数也是$pages
你这个应该要计算要清楚,如果有小数点的要+1的
$pages=ceil($count/$list_num); 这里这个总页数是正确的,不过要判断一下$list_num不能为0哦

$pages=ceil($count/$list_num); 这里这个总页数是正确的,不过要判断一下$list_num不能为0哦 不好意思我是个菜鸟,所以想加问一句,我这个$list_num是之前定义过等于30的,为什么还要判断不能为0呢?还有就是那我的尾页语句应该怎么写?如果我写成>

有定义了就好,只是你怎么会计算出小数了呢?ceil这个可是取整数的啊
$pageno=($offset/$list_num)+1;
你这个干吗还要算一次呢?
你那个文本框里默认的不应该是当前页么?就算不是当前页,这里不应该重新算吧?就算要重新算,你也要取整数啊
php页面首部出现一大段注释说明,怎么找到是哪写的,
注释的内容,如下:
$pageno=($offset/$list_num)+1;
你这个干吗还要算一次呢?
你那个文本框里默认的不应该是当前页么?就算不是当前页,这里不应该重新算吧?就算要重新算,你也要取整数啊 那是不是我应该把这句去掉?
$pageno=($offset/$list_num)+1;然后把第$pageno页改成第$pages页?
$pageno=floor(($offset/$list_num)+1); //改成这样呢
$pageno=floor(($offset/$list_num)+1); //改成这样呢 嗯,跳到最后一页了,但是最后一页只显示列表的头
$pageno = ceil($offset/$list_num);
ceil 取得 大于等于 $offset/$list_num 的最小整数
$pageno = ceil($offset/$list_num);
ceil 取得 大于等于 $offset/$list_num 的最小整数 嗯,问题是这样的话,第1页显示的是第0页,我还是直接不要尾页这个功能了吧

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
