I did some 'playing' in this area a little while ago, with some
success, but did not complete it due to some other technical
difficulties that I did not have time to resolve. Anyhow, I was saving
the buffered output as an MD5'd name including session variables and
the requested URL string to ensure that the effect of session
variables was taken into consideration. The code may help.
The code was:
(please excuse any poor coding, I've only been doing PHP a year)
<?php
// Class to handle hashing and file checking/retrieval
include("includes/staticHtml.inc.php");
if ($_SERVER['QUERY_STRING'])
$to_hash = $_SERVER['PHP_SELF'].$_SERVER['QUERY_STRING'];
else
$to_hash = $_SERVER['PHP_SELF'];
$static = new static_html($to_hash, $_SESSION);
if ($static->status == 'new') // Did not exist
{
ob_start(); // Start output buffering
}else{
echo $static->html;
exit();
}
// Page processing here
$str = ob_get_contents();
//Save static html
$static->save_html($str);
ob_flush();
?>
**** includes/staticHtml.inc.php ****
<?php
class static_html
{
var $status;
var $html;
var $hash;
var $static_path;
function static_html($fullUrl, $session)
{ // constructor
$this->$static_path = "/static";
$ssn = implode('_',$session);
$this->hash = md5($fullUrl.$ssn);;
$this->find_html();
}
function find_html()
{
$path = $this->$static_path.$this->hash.'.htm';
if (file_exists($path))
{
$this->html = file_get_contents($path);
$this->status = 'old';
}else{
$this->status = 'new';
}
}
function save_html($str)
{
if ($this->find_html() != 'old')
{
// save html
$path = $this->$static_path.$this->hash.'.htm';
$fp = fopen($path,'w');
$sts = fwrite($fp,$str);
fclose($fp);
}
}
}
?>
