Three homepage news publishing makes it easier for you to update (on)
-------- Each time you add a message to the homepage and add two sentences, You have to upload the entire page. This is really not worth it! As a result, lazy people like lanfeng have come up with a permanent solution to implement dynamic real-time, remote management and editing, and automatic maintenance. It can also be used as a virtual Community . (If you change it, you can automatically generate a feed for your news center on the homepage .) Forgive me for all these features.
-------- Insert a few digress first. When we build a website, do we use HTML to embellish PHP in the middle or use PHP to generate HTML? Professional websites can centralize a function on one page and call different modules to implement each sub-function. (does the client have only one page? I have not tried ). In any case, software reuse with modular functions is an important method for efficient development (it can also save your host space ).
-------- Okay. let's modularize the functions. Read carefully for beginners Code Pay special attention to the usage of basic functions. Experts can skip this section, huh, huh (so seriously? I am so sorry -().
<? PHP
/* Head. php to avoid being directly typed into head. Inc to download your Source code , It is best to use PHP as the suffix so that your server will first intercept it for processing */
Echo "<HTML> Echo "the path to network management" // if the title changes frequently, you can create a function.
Echo "</title> ?>
This is a functional block for writing HTML headers.
<? PHP
/* Makestr. php defines a function that processes hyperlinks in the public text, assuming the link form in the text is $ {http://www.yoyonow.net | Network Management path }*/
Function makestr ($ text)
{$ STR = $ text;
$ A = strstr ($ S, '$}'); // remove the substring before '$ {' in $ S.
If ($ ){
$ B = strstr ($ ,'}');
If ($ B ){
$ LA = strlen ($ A); $ ls = strlen ($ S); // obtain the string length
$ S = substr ($ A, 0, $ LS-$ la); // obtain the substring. The second parameter is the starting point, and the third parameter is the number of characters.
$ A = substr ($ A, 2); // remove '$ {'
$ LB = strlen ($ B); $ LA = strlen ($ );
$ A = substr ($ A, 0, $ la-$ lb); // retrieve the hyperlink
$ B = substr ($ B, 1); // remove '}'
$ Ta = strstr ($ A, "|"); // you can specify whether the link text exists.
If ($ Ta ){
$ LA = strlen ($ A); $ lT = (strlen ($ Ta );
$ Linktext = substr ($ A, $ la-$ LT + 1 );
$ A = substr ($ A, 0, $ la-$ lt );
}
Else {
$ Linktext = $;
}
$ S = $ S. "<a herf =" ". $ A." ">. $ linktext." </a>. $ B; // prepare the returned string.
}
}
Return ($ S );
}
-------- If you are a newbie, you should look for an HTML getting started book. Otherwise, it is difficult to become a PHP master. These functions that you start to look very simple and process strings. After your clever use, you can do a lot of beautiful things. In the next lecture, we can see the results we have prepared for a long time.
