Update: Amazon has now made it so you can set expiration times on objects in S3, see more here: https://forums.aws.amazon.com/ann.jspa?annID=1303
Recently I was working on a project where we upload backups to Amazon S3. I wanted to keep the files around for a certain duration and remove any files that were older than a month. We use the s3cmd utility for most of our command line based calls to S3, however it doesn’t have a built in “delete any file in this bucket that is older than 30 days” function. After googling around a bit, we found some python based scripts, however there wasn’t any that was a simple bash script that would do what I was looking for. I whipped this one up real quick, it may not be the best looking but it gets the job done:
So earlier today I was working on a Facebook App and wanted to use “partials” in a similar fashion as Symfony’s partials. At this point, I realized I had no idea how Symfony placed variables into the current execution scope when you do things like
include_partial("somePartial", array("foo" => $foo, "bar" => $bar));
A bit of digging led me to the extract() function in PHP.
From the documentation, “extract — Import variables into the current symbol table from an array”.
