simple file cache and check in php
just a quick cache bit of code, may need tweaking to actually work... i just added it here as i thought it was re-usable.
Also requires simple_html_dom library.
PHP
/* file cache */
require_once("lib/simple_html_dom.php");
$import_url_md5 = md5($import_url);
$current_working_directory = getcwd();
$filename = $current_working_directory . "/cache/" . $import_url_md5 . ".html";
$filename_link = "/cache/" . $import_url_md5 . ".html";
// cache it... or not...
$file_cache = true;
if($file_cache) {
if(file_exists($filename)) {
$out .= "using cache file: <a href='$filename_link'>$filename_link</a> <br />";
$html = file_get_html($filename);
} else {
$out .= "added cache file: <a href='$filename_link'>$filename_link</a> <br />";
$html = file_get_html($import_url);
// save it for later...
file_put_contents(
$filename,
$html
);
}
} else {
// no cache
$out .= "cache disabled<br />";
$html = file_get_html($import_url);
}
// return $out;
// exit();
