When we browsed some websites, we often saw news that was just updated. If we had manual maintenance, it would be a very tedious task. However, we can Program To control the update operation, it will become very convenient (I am not going to be lazy ).

Here, I use PHP to implement this function. The principle is to sort the news in reverse order based on the news release time, and display the News Connection list on a page. Each connection corresponds to a news content webpage. The procedure is as follows:

1. First, create a directory under your site and save the edited news pages under this directory. In the future, all news pages will be placed here for easy maintenance. News pages are in hypertext format (not to mention html ), the first behavior is "<HTML>

2. Write a program to automatically update news (assuming the file name is paixu. php)

The source program is as follows:

<? PHP
$ Fp = array ("FILENAME" => "", "filetime" => "", "firstline" => ""); // create an array to save the file name and the first line of the file
$ Dd = Dir ('Save the news directory'); // read the Save directory of the news File
$ I = 0;
Clearstatcache ();
While ($ file = $ DD-> Read () // read the files in the directory cyclically
{
If (is_file ($ DD-> path. "/". $ file ))
{
$ FP [$ I] ["FILENAME"] = $ DD-> path. "/". $ file; // save the file name
$ Fr = fopen ($ DD-> path. "/". $ file, "R ");
$ FP [$ I] ["firstline"] = fgetss ($ FR, 60 ); // remove the HTML Tag and save the first line of the file (that is, why do we need to write the news header line in the required format)
Fclose ($ fr );
If ($ time = date ("y m d H: I", filemtime ($ DD-> path. "/". $ file) // save the file time as the sorting condition.
{
$ FP [$ I] ["filetime"] = $ time;
}
$ I ++;
}
}
$ I = count ($ FP); // number of files saved
$ I-= 4;
For ($ J = 0; $ j <$ I; $ J ++) // follow the bubble Algorithm Sort (Computer reports already exist Article Introduced, I am not so arrogant)
For ($ k = $ I; $ k> $ J; $ k --)
If ($ FP [$ J] ["filetime"] <= $ FP [$ K] ["filetime"])
{
$ C = $ FP [$ J] ["filetime"];
$ Fname = $ FP [$ J] ["FILENAME"];
$ Fcontent = $ FP ["$ J"] ["firstline"];
$ FP [$ J] ["filetime"] = $ FP [$ K] ["filetime"];
$ FP [$ J] ["FILENAME"] = $ FP [$ K] ["FILENAME"];
$ FP [$ J] ["firstline"] = $ FP [$ K] ["firstline"];
$ FP [$ K] ["filetime"] = $ C; // line30
$ FP [$ K] ["FILENAME"] = $ fname;
$ FP [$ K] ["firstline"] = $ fcontent;
}
For ($ I = 0; $ I <= (count ($ FP)-4); $ I ++) // read the saved file information and connect it accordingly
{
Echo "<tr> <TD> ";
Echo "<a href = ". $ FP [$ I] ["FILENAME"]. "> ". $ FP [$ I] ["firstline"]. "</a> ";
Echo "</TD> <TD class = font1> ";
Echo "(". $ FP [$ I] ["filetime"]. ") <br> \ n ";
Echo "</TD> </tr> ";
}
$ DD-> close ();
?>

3. Put the program and directory on your website, and then input http: // website name/directory/panxu. php In the browser. Can you see it?

Finally, let's say a few more words (I am not making more money, but mainly serving the people). Your website must support the PHP function.

In addition, I only provide basic functions. You can add more control functions, as well as page modification and beautification. What do you need? Do you mean I am not responsible? I am suffering ...). Well, it will be here first. What is wrong, please give me more advice, can send email: zbclh@sina.com and I contact.
