PHP generates HTML files in various ways introduction _php tutorial

This article introduces three kinds of methods that can be used to generate HTML files in PHP, before using PHP's Ob_start, followed by a friend of the Smarty template to generate the method.

I often see people on the Internet to ask how to static the entire dynamic site, in fact, the method is very simple.

The code is as follows	Copy Code
Add Ob_start () at the beginning of your service; Ob_start (); Here's your code. Add Ob_end_clean () at the end and output this page to a variable $temp = Ob_get_contents (); Ob_end_clean (); Write file $fp = fopen (' filename ', ' w '); Fwrite ($FP, $temp) or Die (' Write file error '); ?>

This is only the most basic method, is not very practical, because the site is to be updated, to periodically regenerate the HTML
Here's how I use it:

The code is as follows

Copy Code

if (file_exists ("xxx.html")) { $time = time (); File modification time and the current time difference of half an hour, direct to the HTML file, otherwise regenerate HTML if ($time-filemtime ("xxx.html") < 30*60) { Header ("Location:xxx.html"); } } Add Ob_start () at the beginning of your service; Ob_start (); Detailed content of the page Add Ob_end_clean () at the end and output this page to a variable $temp = Ob_get_contents (); Ob_end_clean (); Write file $fp = fopen (' xxx.html ', ' W '); Fwrite ($FP, $temp) or Die (' Write file error '); Re-orientation Header ("Location:xxx.html");

The cache files used above will be overloaded when generated in large numbers, so let's introduce a more efficient approach

The following is the submission page for the input content:
File name: aa.html

The code is as follows	Copy Code
Submit Page

Here is the code snippet:
File name: bb.php

The code is as follows

Copy Code

Defining date Functions function GetDateTime () { $datetime =getdate (); $strReturn = $datetime ["Year"]. " -"; $strReturn = $strReturn. $datetime ["Mon"]. " -"; $strReturn = $strReturn. $datetime ["Mday"]; return $strReturn; } Defining a Time function (file name) function gettime () { $times =getdate (); $strtime = $times ["Year"]; $strtime = $strtime. $times ["mon"]; $strtime = $strtime. $times ["Mday"]; $strtime = $strtime. $times ["Minutes"]; $strtime = $strtime. $times ["seconds"]; return $strtime; } ?> Determine if the commit value is empty $submit =$_post["Submit"]; Defining File header Information $htmltitle =$_post["HTMLTitle"]; Define file Contents $htmlbody =$_post["HTMLBody"]; if ($submit) { Defining HTML file Tags $html 1= $html 1. ""; $html 1= $html 1. ""; $html 1= $html 1. ""; <br/> $html 1= $html 1. $htmltitle <br/> $html 1= $html 1.""; $html 1= $html 1. " "; $html 1= $html 1. ""; $html 1= $html 1. ""; $html 1= $html 1. " "; $html 1= $html 1." "; $html 1= $html 1. $htmltitle; $html 1= $html 1. " "; $html 1= $html 1. $htmlbody; $html 1= $html 1. " "; $html 1= $html 1. ""; $html 1= $html 1. ""; Determine if today's folder exists if (!is_dir (GetDateTime ())) { If it does not exist, establish mkdir (GetDateTime (), 0777); } Write HTML file $filedir =getdatetime (); $filename =gettime (); $filename = $filename. ". HTML "; $FP =fopen ("$filedir/$filename", "w"); Fwrite ($fp, $html 1); Fclose ($FP); echo ""; } ?>

If the prompt file is successfully written, then you will succeed, then go back to your corresponding directory to see if there is any static HTML file generated!

Smarty Template Generation Method

The code is as follows

Copy Code

Require_once ("./config/config.php"); Ob_start (); $id =$_get[id]; $sql = "SELECT * FROM table_name where id= ' $id '"; $result =mysql_query ($sql); $rs =mysql_fetch_object ($result); $smarty->assign ("Showtitle", $rs->title); $smarty->assign ("Showcontent", $rs->content); $smarty->display ("content.html"); $this _my_f= ob_get_contents (); Ob_end_clean (); $filename = "$id. html"; Tohtmlfile_cjjer ($filename, $this _my_f); File Generation function function Tohtmlfile_cjjer ($file _cjjer_name, $file _cjjer_content) { if (Is_file ($file _cjjer_name)) { @unlink ($file _cjjer_name); exist, delete it } $cjjer _handle = fopen ($file _cjjer_name, "w"); Create a file if (!is_writable ($file _cjjer_name)) {//Judge Write permission return false; } if (!fwrite ($cjjer _handle, $file _cjjer_content)) { return false; } Fclose ($cjjer _handle); Close pointer return $file _cjjer_name; Return file name } ?>

There is a method fetch () in smarty that gets the template page content, and it declares the prototype as follows:

The code is as follows	Copy Code
function fetch ($resource _name, $cache _id = null, $compile _id = null, $display = False) ?>

The first parameter is the template name, the second parameter is the cached ID, the third parameter is the compilation ID, and the fourth parameter is whether the template content is displayed. Generate static page We need to use this method.

The code is as follows

Copy Code

$smarty = new Smarty (); Other template substitution syntax ... The following sentence gets all the contents of the page, note that the last parameter is False $content = $smarty->fetch (' template name. TPL ', NULL, NULL, FALSE); The following writes the contents to a static file $fp = fopen (' news.html ', ' W '); Fwrite ($fp, $content); Fclose ($FP); OK, here This news.html static page is generated, you can handle your next work. ?>

All right, in combination with the above method, we generate the file almost the same way, first read out the data and then give us a defined template, and finally use the fopen function to generate a. html file.
