本文实例讲述了php获取文章的方法。分享给大家供大家参考。具体方法如下:
今天发现一个站的出现问题,是直接到了本频道最新发布的文章了,按原理应该是文章本身ID的前与后的ID才是上下页吧,下面我来与大家详细讲述一下.
先看个例子:1,2,3,4,5.
假如上面5个是ID了,我要对我们要用order by id asc得出的排序应该是,4,好了原理就这么简.
sql实现方法,代码如下:
:
代码如下:
$sql ="Select 字段 from 表名 where id>3 order by id asc limit 1";
得出的结果与我们想的是一样的,好了最后我把自己以前写的一个函数分享给各位,代码如下:
代码如下:
/*
int $tag 0
int $fid
*/
function nextPre($tag=0,$zid,$fid)
{
if( $tag )
{
$sql ="Select 字段 from 表名 where id
}
else
{
$sql ="Select 字段 from 表名 where id>$fid order by id asc limit 1";
}
//$sql = "Select * from 表名 where order by id desc limit 0,10";
$result = mysql_query($sql) or die('query error');
if( mysql_num_rows( $result ) )
{
$rs = mysql_fetch_array( $result );
return "".$rs['title']."";
}
else
{
return '没有了';
}
}
希望本文所述对大家的PHP程序设计有所帮助。

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.
