Cache Xml Files — Twitter Api

I have built a small database which use the Twitter API to extract data from the listed members XML files (http://twitter.com/users/show.xml?screen_name=username) and it works well, but since the database makes several calls everytime a page loads I get kicked out very quickly, even with a small memberbase. So I wonder what solution would help with this problem?

I have considered dropping the XML data into the database and saving each XML file on the server, but I am not sure what solution would be best?

Help. Php Delete Old Files

I need YOUR help with a piece of code. My body normally helps me, but he’s on vacation.

I have a folder (/var/www/html/upload/files/) where files are uploaded to. There can be files at the root of (/uploads/) and there can be files in subfolders of (/uploads/). eg: (/uploads/subfolder1/files_here), (/uploads/subfolder2/files_here)

I want to modify my script (below) that only delete old files at the root (/uploads/), to also delete files (but NOT subfolders) older than 10 days. Do not delete subfolders, regardless of date.

You can modify the existing code to make it more efficient, if you have time/patience.
I’m grateful for your help.

This is the code I have for the root folder (not recursive):
$dir = ‘/var/www/html/upload/files/’;

echo «STARTING\n»;
if (is_dir($dir)) if ($dh = opendir($dir)) while ($file = readdir($dh)) if(!is_dir($dir.$file)) if (filemtime($dir.$file) < strtotime('-10 days')) < //if 10 days old, delete
echo «Deleting $dir.$file (old)\n»;
unlink($dir.$file);
>
>
>
> else echo «ERROR. Could not open directory: $dir\n»;
>
> else echo «ERROR. Specified path is not a directory: $dir\n»;
>
closedir($dh);
echo «DONE\n»;

Delete Files From Server

I have a php script that I wrote that enters information into a database and uploads images to the server.

What I need to do now is delete the files from the server when the corresponding database records are deleted. How would I go about doing that?

Delete Files After X Amount Of Time

Im a newb here, so bear with me! Still learning the ropes.

I want to delete all files from my server that are 6 hours old since being uploaded to the site. I believe i need a cron job? I currently have this script in its framework.

//time interval for deletion to occur.
$x = 30;

//the file you wish to delete
$file_name = ‘file.txt’;

//extract difference
$difference = $current_time — $file_creation_time;

//if difference = $x. then delete file
if ($difference == $x) unlink($file_name);
>

Would that work automatically or would it need a cron to run it?

And how could i test it, that bit worries me.

Script To Delete Files And Database Entries Based On Date

Maybe some of the great coders here can help this noob out.
So here is what I have so far:

Code: [Select]//set age criteria for deletion
$age = 60;

//get current date
$datenow = date(«Y-m-d»);

//set the range we want to delete
$delete_range = $datenow — $age;

//get old user_id from users table
$oldusers_users = mysql_query («SELECT user_id FROM users WHERE lastvisit < $delete_range ");

//get user_id from images table that correspond to users table
$oldusers_images = mysql_query («SELECT user_id FROM images WHERE $oldusers_users=user_id.images «);

//find folders that correspond to the usernames and delete
$oldusers_files = mysql_query («SELECT username FROM users WHERE lastvisit < $delete_range ");
//print out username
//$result = mysql_($oldusers_files);
$foldername = mysql_result($oldusers_files, 0);

$sigspath = «sigs/»;
unlink($sigspath . $foldername . «.gif/index.php»);
rmdir($sigspath . $foldername . «.gif»);
//now delete user_id’s from database
mysql_query(«DELETE * FROM users WHERE user_id=$oldusers_users»);
mysql_query(«DELETE * FROM images WHERE user_id=$oldusers_images»);
unset($oldusers_users, $oldusers_images, $oldusers_files, $foldername, $sigspath );
mysql_close($link);
Right now it is only returning the first entry, not the entire list that meets the criteria. It does delete that one file though but does not remover the rows from the database.

I am sure the database stuff is jacked up I am really new to that part. What am I doing wrong here or is there a better way to do this perhaps

Cache A File

I need to know when a file was last modified to see if the browser has an updated cached version, if the browser does use its cache otherwise get the most current version.

Problem With Cache?

I have some JavaScript that sends an AJAX request to the following PHP script every 4 seconds. The idea behind this is that every 4 seconds a new, randomly generate piece of content is loaded. This works fine in Firefox and Chrome, however when I test it in IE it seems to just load the same piece of content over and over again. I’m pretty sure there is nothing wrong with the script so could this be something to do with IE caching the first piece of content returned? Thanks for any help.

$random_number = 0;
$random_number = rand(1,6);

Cache Headers

Hi Guys I have recently been looking into implementing browser caching after reading this: https://developers.g. ctices/caching There are a few things in that google article that don’t make much sense to me so I’m hoping someone can clarify. Firstly Question The document says: » we recommend that you configure your web server to explicitly set caching headers and apply them to all cacheable static resources» This implies you can set caching headers for just some resources. How would you do this? Lets assume I only wanted to set caching headers for a file styles.css — would I need to output headers within the CSS file and then change the extension to .php? e.g.

Second question Etags have me very confused. How would you set etag headers for specific files and then generally? And if you set the etag in the header of the main php page does that mean everything gets cached? Any help someone can provide would be very, very welcome! Drongo

Twitter Cache?

Does anyone know how to cache Tweets as to not reach the API rate limit? I am using the Twitter-provided widget to display multiple profiles on a website, but the API hits the limit of 150 per hour. Is there any way to cache the Tweets and still use this widget? Or does anyone know of a good widget that caches, or simple code?

If anyone knows, please explain in newbie terms.

Cache Question

I have a question about caching files, the way i have seen people do it on tutorials is they save the file to a cache/ folder if non exists, then check if it exists when the page loads so if it doesn’t then load the file normally or if it does then include the cache/file but what is the difference? if the browser has to load the file every time someone goes to it so you cache it for better performance isn’t including the cache/file just the exact same thing? the server still has to download the included cached file.
