Code _php Techniques for general PHP dynamic generation of static HTML Web pages

We know that PHP read MySQL dynamic display, in the case of large access, there will be a lot of performance problems, if the rental of other people's virtual host, will be due to excessive CPU consumption is limited CPU, resulting in web pages can not be accessed. I am here to give a PHP dynamic generation of HTML method, can greatly reduce the server CPU load.

First set up the. htaccess file to convert the dynamically invoked parameter to a static HTML URL address, such as a file that will be in the post directory, forwarded to the wp-post.php file in the root directory, and a similar statement to include:

Rewriterule ^post/([a-z0-9\-]+\.html) $ wp-post.php?$1$2

Then modify the wp-post.php file and add the following PHP code at the beginning of the file:

Copy Code code as follows:

Ob_start ();
$qstring = Isset ($_server[%26quot; Query_string%26quot;]) ? $_server[%26quot; Query_string%26quot;] :%26quot;%26quot;;
Define (%26quot; Html_file%26quot, $_server[' Document_root '].%26quot;/post/%26quot; $qstring);

if (file_exists (html_file))
{
$LCFT = Filemtime (html_file);
if (($LCFT + 3600)%26gt; time ())//Determine if the HTML file was last generated for more than 1 hours, if there is no direct output of the file content
{
Echo (file_get_contents (html_file));
Exit (0);
}
}

Then there is the existing PHP code, followed by the following PHP code at the end of the current code:

Copy Code code as follows:

Define (%26quot; htmlmeta%26quot;,%26quot;%26lt;! --a real static HTML file created at%26quot;. Date (%26quot; Y-m-d h:i:s%26quot).%26quot; --%26gt;%26quot;);
$buffer = Ob_get_flush ();
$fp = fopen (html_file,%26quot;w%26quot;);
if ($FP)
{
Fwrite ($FP, $buffer. Htmlmeta);
Fclose ($FP);
}

OK, then look at your static HTML page, and if there's a comment line at the end of the page, you've successfully created a static HTML file.

One application of this method is the%26ldquo I wrote earlier; WordPress Annual Blog Statistics plug-in%26rdquo, the statistical plug-ins because of the query 10 times database, many people visit the time will have a lot of performance problems, using my introduction of this dynamic generation of HTML technology, one day to query, generate a ranking of statistics, solves the query database performance problem perfectly.
