本文实例讲述了thinkphp浏览历史功能实现方法,分享给大家供大家参考。具体实现方法分析如下:
历史浏览功能都是使用了cookie功能记录用户信息放到了本地了,这样我们只要读取存储在cookies中的值就可以了,下面来给大家介绍一个基于thinkphp 实现浏览历史功能例子。
就像浏览器一样,能够记录访问了哪些页面,这样能够减少时间,下面我们实现浏览历史的功能。
1.在你需要记录浏览数据的产品或新闻页面,记录cookie需要保存的信息,例如下面这行代码,把页面ID,产品名称,价格,缩略图,网址传给cookie_history。
2.function.php 里面添加代码
+----------------------------------------------------------
* 浏览记录按照时间排序
+----------------------------------------------------------
*/
function my_sort($a, $b){
$a = substr($a,1);
$b = substr($b,1);
if ($a == $b) return 0;
return ($a > $b) ? -1 : 1;
}
/**
+----------------------------------------------------------
* 网页浏览记录生成
+----------------------------------------------------------
*/
function cookie_history($id,$title,$price,$img,$url){
$dealinfo['title'] = $title;
$dealinfo['price'] = $price;
$dealinfo['img'] = $img;
$dealinfo['url'] = $url;
$time = 't'.NOW_TIME;
$cookie_history = array($time => json_encode($dealinfo)); //设置cookie
if (!cookie('history')){//cookie空,初始一个
cookie('history',$cookie_history);
}else{
$new_history = array_merge(cookie('history'),$cookie_history);//添加新浏览数据
uksort($new_history, "my_sort");//按照浏览时间排序
$history = array_unique($new_history);
if (count($history) > 4){
$history = array_slice($history,0,4);
}
cookie('history',$history);
}
}
/**
+----------------------------------------------------------
* 网页浏览记录读取
+----------------------------------------------------------
*/
function cookie_history_read(){
$arr = cookie('history');
foreach ((array)$arr as $k => $v){
$list[$k] = json_decode($v,true);
}
return $list;
}
3.在需要显示浏览记录的页面输出信息
模板里面用volist显示出来就行了。
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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
