If you have implemented a PHP application using an object oriented approach and are disappointed with the performance you get, then this article is worth looking at. Here I will explain how you can use templates to cache your web pages and serve pure static pages. Using this technique you can have complex algorithms for rendering articles, or whatever you like, and still get the performance of static pages.

If you are wondering about how templates works please read the article about block templates here. This first code snippet shows how you can implement the page caching mechanism. Here I check if page caching is enabled, if it is disabled the page is just generated as usual. If page caching is enabled the code checks for a cached version. If there exists no cached versions of the page, one is generated.

// read from .ini file 
$PageCaching = "enabled"

// check if caching is enabled
if ( $PageCaching == "enabled" )
{
    $cachedFile = "cache/page.cache";
                    
    if ( file_exists( $cachedFile ) )
    {
        include( $cachedFile );
    }
    else
    {
        createPage( true, $cachedFile );
    }            
}
else
{
    createPage( false );
}
