PHP method to generate static pages and detailed version of implementation code_PHP tutorial

The main ones used in php are fread() and fwirte(). After the static page is generated, it will involve modification issues. Here you can use the regular matching method to replace the changed parts of the template. However, this method is too troublesome. The recommended method is to directly cut off the originally generated template and regenerate it. Haha, it is really done.
Another point that needs to be explained is that this method of generating static pages is generally used for pages that change infrequently, such as the final page of information. For list pages, it is also advisable if the information is not updated very frequently. Nowadays, there are many popular blog or forum programs on the Internet that can generate static pages. They all generate HTML "semi-automatically" by manually clicking the "Generate HTML Page" button in the background. But for some portal websites with a very large amount of information, it will not work. Because static pages are called "static" because they cannot change automatically. If the information list is updated 100 times a day, then the static list page will be regenerated 100 times. If I had 10 columns like this, it would be enough to make me vomit blood just thinking about it.
Okay, without further ado, let’s take a look at the actual program demonstration:
First: It is implemented using the ob function. The code is relatively simple and the efficiency is relatively high.

Copy code The code is as follows:

ob_start();
@readfile(" http://tools.jb51.net/");
$text = ob_get_flush();
$myfile = fopen("myfile.html","w");
$text =
str_replace ("{counent}",$string,$text);
fwrite($myfile,$text);
ob_clean();
?>

Because even if you want to generate a static page, the dynamic reading part must be retained. After inserting the data into the database, pass the url to the readfile function, then read it into the cache, and fwrite to generate a static page. This is what Tutuo appreciates most. A practice. The fewest lines of code and the highest efficiency. http://tools.jb51.net/ is a bare page, that is, pure content, without header, tail, or menu. In this way, you can customize your own template myfile.html more freely. If you only require the generation of static pages, this basically meets the needs.
second: Generate static html page normally.
This method is to do it step by step, fread the page, and then str_replace the replacement
First, create the final content page:
PHP code

Copy code The code is as follows:

$title = "http://siyizhu.com test template";
$file = "TwoMax Inter test templet,
author：[email=Matrix@Two_Max]Matrix@Two_Max[/email]";
$fp = fopen ("temp.html","r");
$content = fread($ fp,filesize ("temp.html"));
$content = str_replace("{file}",$file,$content);
$content = str_replace("{title}",$title, $content);
$filename = "test/test.html";
$handle = fopen ($filename,"w"); //Open the file pointer and create the file
/* Check whether the file Created and writable*/
if (!is_writable ($filename))
{
die ("File: ".$filename." is not writable, please check its properties and try again!") ;
}
if (!fwrite ($handle,$content))
{ //Write information to file
die ("Generate file".$filename."Failed!");
}
fclose ($handle); //Close pointer
die ("Create file".$filename."Success!");
?>

This step is relatively simple. It's just a matter of simple variable substitution. If you want to generate a static list page, the principle is the same. Use a program to generate a list of articles, treat it as a large variable, and replace the variables in the template. This is how the page turning page of the list is. Of course, if the information is updated, the list page will also need to be regenerated.
PHP code

Copy code The code is as follows:

$title = "http://";
$file = "TwoMax Inter test templet,
author:[email=Matrix@Two_Max]Matrix@ Two_Max[/email]";
$fp = fopen ("temp.html","r");
$content = fread ($fp,filesize ("temp.html"));
$content = str_replace ("{file}",$file,$content);
$content = str_replace ("{title}",$title,$content);
//Start generating list
$list = '';
$sql = "select id,title,filename from article";
$query = mysql_query ($sql);
while($result = mysql_fetch_array ($query))
{
$list .= ''.$result['title'].'
';
}
$content .= str_replace("{articletable}",$list,$content);//End of generating list
// echo $content;
$ filename = "test/test.html";
$handle = fopen ($filename,"w");
//Open the file pointer and create the file
/* Check whether the file is created and writable */
if(!is_writable ($filename))
{
die ("File: ".$filename." is not writable, please check its properties and try again!");
}
if(!fwrite($handle,$content))
{ //Write information to the file
die ("Generate file".$filename."Failed!");
}
fclose($handle); //Close pointer
die ("Create file ".$filename." Success! ");
?>

About page turning:
If we specify paging, there are 20 articles per page. The articles in a certain sub-channel list are 45 after the database query, then , First, we obtain the following parameters through query: 1. Total number of pages; 2. Number of articles per page. Second step, for ($i = 0; $i < allpages; $i++), page element acquisition, analysis, and articles. Generation, are all executed in this loop. The difference is that the sentence die ("Create file".$filename."Success!"; is removed and placed in the display after the loop, because this statement will terminate the program execution.
Example:
PHP code

Copy code The code is as follows:

$fp = fopen ("temp.html","r");
$content = fread ($fp,filesize ("temp.html"));
$onepage = '20';
$sql = " select id from article where channel='$channelid'";
$query = mysql_query ($sql);
$num = mysql_num_rows ($query);
$allpages = ceil ($num / $onepage );
for ($i = 0;$i<$allpages; $i++)
{
if ($i == 0)
{
$indexpath = "index.html ";
}
else
{
$indexpath = "index_".$i."html";
}
$start = $i * $onepage;
$list = '';
$sql_for_page = "select name,filename,title from article where channel='$channelid' limit $start,$onepage";
$query_for_page = mysql_query ($sql_for_page);
while ($result = $query_for_page)
{
$list .= ''.$title.'
';
}
$content = str_replace("{articletable}",$list,$content);
if (is_file ($indexpath))
{
@unlink ($indexpath); //If the file already exists, delete it
}
$handle = fopen ($indexpath,"w"); //Open the file pointer and create the file
/*Check whether the file is created and writable*/
if (!is_writable ($indexpath))
{
echo "File: ".$indexpath." is not writable, please check its properties. Try again! "; //Modify to echo
}
if (!fwrite ($handle,$content))
{//Write information to the file
echo "Generate file".$indexpath." fail! "; //Modify to echo
}
fclose ($handle); //Close pointer
}
fclose ($fp);
die ("Generating paging file is completed, as generated Not complete, please check the file permission system and regenerate! ");
?>

Third: smarty template generates static pages
smarty itself has a fetch function, which has a few functions Similar to fread(), it can be used to generate static pages.
This example must look familiar to you. Yes, the example of the fetch function in the smarty manual is always classic compared to the official example! PHP code

Copy code The code is as follows:

include("Smarty.class.php" );
$smarty = new Smarty;
$smarty->caching = true;
// only do db calls if cache doesn't exist
if(!$smarty->is_cached ("index.tpl"))
{// dummy up some data
$address = "245 N 50th";
$db_data = array("City" => "Lincoln", "State " => "Nebraska", "Zip" => "68502");
$smarty->assign("Name","Fred");
$smarty->assign("Address ",$address);
$smarty->assign($db_data);
}// capture the output
$output = $smarty->fetch("index.tpl");
//This place is the key// do something with $output here
echo $output; //hoho see the output result, then what? After fwrite, we will get the result we want.
$fp = fopen("archives/2005/05/19/0001.html", "w");
fwrite($fp, $content);
fclose($fp);

PHP code

Copy code The code is as follows:

ob_start();
echo "Hello World!";
$content = ob_get_contents();//Get all the content output by the php page
$fp = fopen("archives/2005/05/19/0001.html", " w");
fwrite($fp, $content);
fclose($fp);
?>
