One, PHP script with dynamic page.
PHP script is a server-side script, can be embedded and other methods and HTML files can be mixed, or class, function encapsulation and other forms, in the form of templates to the user request processing. In any way, the rationale for it is such. Requested by the client, request a page-----The >web server introduces the specified script for processing-----> script is loaded into the server-----> parsing the script by the server-specified PHP parser forms the HTML language----> The parsed HTML statement is passed back to the browser in a package way. It is not difficult to see that after the page is sent to the browser, PHP does not exist, has been converted into an HTML statement. Customer requests for a dynamic file, in fact there is no real file exists there, is the PHP parsing the corresponding page, and then sent back to the browser. This kind of page processing is called "Dynamic page".
Second, PHP static page.
A static page is a page that does exist on the server side that contains only HTML and client-run scripts such as JS,CSS. The way it's handled is. A request is made by a client requesting a page----the >web server confirms and loads a page----The >web server passes the page back to the browser as a package. From this process, we compare the dynamic page, you can now. The dynamic page needs to be parsed by the PHP parser of the Web server, and it is usually necessary to connect the database, make the database access operation, then the HTML language information packet can be formed, while the static page, no need to parse, need not connect the database, send directly, can greatly reduce the server pressure, improve the server load capacity, Dramatically provides page opening speed and website overall opening speed. However, the disadvantage is that the request cannot be processed dynamically and the file must exist on the server.
Three, template and template parsing.
The template is not yet populated with the content HTML file. For example:
Temp.html
- <HTML>
- < TITLE > {title} TITLE>
- <BODY>
- Thisisa{file}file ' Stemplets
- BODY>
- HTML>
PHP static page Processing:
- templetest.php
- php
- $ title = "Web Teaching Network test template" ;
- $ file = "Webjxtesttemplet,
Author:web@webjx.com ";- $ 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;
- ?>
Well, compared to the static page and dynamic page each of the pros and cons, now we say, how to generate static files in PHP.
PHP generated static page does not refer to the dynamic parsing of PHP, the output of HTML pages, but the use of PHP to create HTML pages. At the same time, because the HTML is not writable, we create the HTML if there are changes, we need to delete the regeneration. (Of course, you can also choose to use the regular to modify, but personally think that does not make it easier to delete the regeneration is faster, some outweigh the loss.) )
