Amazon S3 Tools, Using PHP

If you haven’t heard of Amazon S3, check it out here. It’s remote storage for your files, at $0.15 per GB per month. You sign up for an account for free, then pay at the end of each month for the GB and data transfer you used. It’s nice and cheap, and I find it better than an FTP account to backup files, for a couple reasons. 1) It’s cheap, pay only for what you use. 2) Interface is all HTTP REST making it easier to interface with in code. 3) It’s cheap 4) You can make select files public readable and available via an HTTP address 5) There is a Firefox extension, S3 Organizer, that looks like an FTP client, you can move files back and forth from your desktop. 6) It’s all the hype right now 7) It’s cheap remote backup.

The HTTP REST interface is easy to use with PHP. I made a few command line utils with PHP:
s3ls <path> – lists file details in S3 account that are prefixed with <path>
s3put <file> – stores file in S3 account in the same dir it’s in on your server
s3get <file> – retrieves file from S3 account – can use absolute path, else it assumes current working directory
s3syncdir <dir> – removes files from S3 that no longer exist on server, then uploads any missing or modified files to S3

Index for God Sake!

Taken from:

http://mysqlhow2.com/viewtopic.php?t=8

If you have a database that is returning slow result you might want to optimize your queries and do indexing.

But how to tell which of the queries need to be optimized.

Lets look at the rulsts of the querey without returning all the results:
You will use the EXPLAIN clause
Explain clause will show rows returned in your query. (The more rows the slower the return)
