php技术生成静态页面的实现（Implementation of static page generation by PHP Technology）php技术生成静态页面的实现(Implementation of static page generation by PHP Technology) One, PHP script and dynamic page. PHP script is a server-side scripting program, which can be mixed with HTML files by embedding and other methods. It can also be used in class, function encapsulation and other forms to deal with user requests in the form of templates. In any way, the basic principle is this. The request from the client requests a page - Web server are introduced to specify the corresponding script processing - script is loaded by the server server - specified PHP parser script analytical form HTML language form - parsing HTML sentence on the way back to the browser. It is not difficult to see, after the page sent to the browser, PHP does not exist, has been transformed into HTML statement. The client requests a dynamic file, and in fact there is no real file, where the PHP corresponds to the page, and then sends it back to the browser. This page processing method is called dynamic page. Two, static page. Static page refers to the server really exists only contains HTML and JS, CSS and other clients run the script page. Its a way of dealing with it. The request from the client requests a page - WEB server to confirm and load a page - WEB server will package the page to transfer back to the browser. From this process, we compare the dynamic page, you can present. The dynamic page is required by the Web server PHP parser parsing, and often need to connect to the database, the database access operation, and then to form the HTML language information packet; and a static page, without analysis, without connecting to the database, sent directly, which can greatly reduce the server pressure, improve server load capacity, providing significant page open speed and website the overall speed of opening. However, the disadvantage is that the request can not be processed dynamically, and the file must exist on the server. Three, template and template analysis. The template has not filled the content HTML file yet. For example: Temp.html Code: Here are the quotes: Title This is a file files templets PHP processing: Here are the quotes: Templetest.php Code: $title = HP enthusiasts test template; $file = TwoMax Inter test templet, Author:Sheyi; $fp = fopen (temp.html, R); $content = FREAD ($fp, filesize (temp.html); $content = str_replace (file, $file, $content); $content = str_replace (Title, $title, $content); Echo $content; ? Template parsing process, the PHP script parsed by the results obtained by filling (content) into the template process. Template classes are usually used. Currently popular template parsing classes are phplib, Smarty, fastsmarty, and so on. The principle of template parsing is usually substitution. Some programmers are accustomed to putting judgment, loop, and other processing into template files, using analytic class processing, the typical application is block concept, simply speaking is a cycle processing. PHP script specifies the number of cycles, how to cycle, replace, etc., and then the template parsing class specific implementation of these operations. Well, compared to the static pages and dynamic pages of their respective advantages and disadvantages, and now we will talk about how to use PHP to generate static files. Static pages generated by PHP do not refer to dynamic parsing of PHP, output HTML pages, but to create HTML pages with PHP. At the same time, because of the non writable of HTML, if we create the HTML, if you want to modify, you need to delete the re generated. Of course, you can also choose regular modifications, But personally think that doing so is better than deleting the re generated faster, some gains outweigh the gains. ) Get down to business。 Used PHP file operation function of PHP FANS know, there is a file operation function fopen in PHP, namely open the file. If the file does not exist, try to create it. This is the theoretical foundation that PHP can be used to create HTML files. You can create a file whenever you have the permissions to write the folder in the HTML file, that is, permissions define 0777. For UNIX systems, the Win system does not need to be considered. Still, for example, if we modify the last sentence and specify a static file named test.html in the test directory: Code: Here are the quotes: $title = extension international test template; $file = TwoMax Inter test templet, Author:_Max MatrixTwo_Max; $fp = fopen (temp.html, R); $content = FREAD ($fp, filesize (temp.html); $content = str_replace (file, $file, $content); $content = str_replace (Title, $title, $content); Echo / / $content; $filename = test/test.html; $handle = fopen ($filename, w); / / create a file to open the file pointer. * Check if the file was created and writable * / If (. Is_writable ($filename) Die (file:.$filename.) is not writable. Please check its properties and try again; If (! Fwrite ($handle, $content) / / information will be written to the file Die (generated file .$filename. failed!); Fclose ($handle); / / close pointer Die (create file .$filename.) succeed!; ? Practical application of common problems solution reference: First, the article list problem: Create a field in the database, log file name, each generates a file, the file name will be automatically stored in the database for the recommended articles, only to the specified folder in the file storing static page. Use PHP operation processing article list, save as string, generate page replace this string. For example, in the page, the list of articles is added to the tag articletable, and in the PHP processing file: Code: Here are the quotes: $title = extension international test template; $file = TwoMax Inter test templet, Author:_Max MatrixTwo_Max; $fp = fopen (temp.html, R); $content = FREAD ($fp, filesize (temp.html); $content = str_replace (file, $file, $content); $content = str_replace (Title, $title, $content); Start / / generate a list $list =; $sql = select id, title, filename from article; $query = mysql_query ($sql); While ($result = mysql_fetch_array ($query) $list =.$resulttitle. ; $content = str_replace (articletable, $list, $content); / / end of list generation Echo / / $content; $filename = test/test.html; $handle = fopen ($filename, w); / / create a file to open the file pointer. * Check if the file was created and writable * / (if! is_writable($文件名) 死(“文件:“美元。文件名。”不可写，请检查其属性后重试”); 如果(fwrite($手柄，$content) /将信息写入文件 死(“生成文件”。$文件名。”失败”); 关闭文件(美元/关闭指针处理); 死(“创建文件”。$文件名。”成功”); , 二、分页问题。 如我们指定分页时，每页20篇。某子频道列表内文章经数据库查询为45条，则，首先我们通过查询得到如下参数:1，总页数;2，每页篇数。第二步，为($我= 0;我 allpages美元美元;i+)，页面元素获取，分析，文章生成，都在此循环中执行。不同的是，死(“创建文件”。$文件名。”成功“;这句去掉，放到循环后的显示，因为该语句将中止程序执行。例: 代码: 以下是引用片段: $ FP = fopen(“温度。HTML”、“R”); $content = fread($ FP，文件大小(“温度。html”); 页=“20美元; SQL =“选择ID美元从第信道= $ channelid ”; 查询= mysql_query美元($ SQL); Num = mysql_num_rows美元($查询); allpages美元=细胞($民元/页); 为($我= 0;美元美元美元我 大致思路如此，其中如其它数据生成，数据输入输出检查，分页内容指向等可酌情在页面中加入。 在实际文章系统处理过程当中，还有许多问题有待考虑，与动态页面不同之处，需注意的地方还有很多但大致思路即是如此，其它方面可举一反三而得。 我们先回顾一些基本的概念。 一、PHP脚本与动态页面。 脚本是一种服务器端脚本程序可通过嵌入等方法与PHP，HTML文件混合，也可以类， The form of function encapsulation is used to deal with users request in the form of template. In any way, the basic principle is this. The request from the client requests a page - Web server are introduced to specify the corresponding script processing - script is loaded by the server server - specified PHP parser script analytical form HTML language form - parsing HTML sentence on the way back to the browser.

If the file does not exist, try to create it. This is the theoretical foundation that PHP can be used to create HTML files.
