Written by : In my previous post, i explained how to cache feeds directly in json format and show them in your web page from the cache file. In this post, i will show you how to get feeds from search api with having multiple usernames and store them in a file. Credit goes to Scott for his work back in 2009, i have modified the script to my taste and clean it a little bit.
1st of all create a directory named cache (better in the same directory where the script will be saved). Change the permissions to write into the directory. Time interval i set to 10 minutes, you can change it in the script. Now copy and paste the following script and save it as anyname.php. You can modify it to your taste as you wish..
<style>
#twitter {
padding:5px 15px;
line-height:1.6em;
}
#twitter ul li{margin:10px 0; background:none; padding:0}
#twitter span a {color:#35d0ff}
#twitter a:link {color:#35d0ff; font-style:italic}
#twitter a:visited {color:#35d0ff; font-style:italic}
</style>

Just run this script in the browser, few changes you might need by changing usernames, one thing more i would like to mention is if you want one user feeds, just input one username like:
parse_twitter_cache_feed(“username”, 5);
And that’s it.
