This may work, although I just made it up. I can see already that you'd
have some problems with multiple scripts running at once. If a script
opens the cache, then a second script saves new cache information before
the first script saves it's data, the first script would overwrite the
second script's update.
Maybe instead of a read at the beginning of script execution, a read at
the beginning of each query would be better?
Save cache results to a file:
<?
// script start
$querycache = unserialize(file_get_contents("query.cache"));
/*
$querycache format:
array('sql' => array(), 'result'=>array(), 'time'=>array());
For each sql statement 'sql' you have a result array.
*/
// run all your queries through a function:
function query($sql) {
$cached = array_search($sql, $querycache['sql'])
// check to see if the result is old
if (time() - $querycache['time'][$cached] > $max_time) {
unset($querycache['time'][$cached]);
unset($querycache['sql'][$cached]);
unset($querycache['result'][$cached]);
$cached = false;
}
if ($cached) {
return $querycache['result'][$cached];
} else {
$result = mysql_query($sql);
$querycache['sql'][] = $sql;
$index = array_search($querycache['sql']);
$querycache['time'][$index] = time();
while ($r = assoc($result)) {
$querycache['result'][$index][] = $r;
}
// save cache for other scripts
file_put_contents('query.cache', serialize($querycache));
return $querycache['result'][$index];
}
}
... It's actually kind of a complicated process now that I'm thinking
about it.

Hi all,
I'm trying to improve the performance for visitors, and I want to know
if there is some way to store the mySQL results of .php scripts in
webpages.
So, in example, when requesting
http://www.mydomain.com/script.php?id=110 , it can be redirected to
his cached version http://www.mydomain.com/id110.html.
Any code or information would be appreciated,
Regards,
