This post looks at how to move an email into Gmail’s trash with PHP IMAP.
When a CSS or Javascript file is changed the visitor’s browser needs to get the latest copy of the file to reflect the changes, but it will have been cached and may cause rendering or functionality issues depending on the changes. To force reloading of the CSS and Javascript file the files should be renamed each time they are changed; this can be automated by using PHP to add the timestamp of the file into the filename.
