When i did some optimization of a cluster based webapp lately, I was wondering how Memcache was speading my cache entries over the cluster. So i did some research for monitoring tools. [...] Inspired by [memcache.php], i wrote a small script that fetches all data from a memcache cluster, gets all keys out of it and then sorts and displays them in a list. Yes it it ugly and yes: the memcacheD is not answering other requests while doing a cachedump.

He includes the 22 line script in the post to spit back the data in a simple array. From there it can be styled whoever you'd like.

Andrey has implemented a little mysqlnd only addition to mysqli_debug(): 'm' - dump memory information. It works like the other options described in PHP: Debugging ext/mysqli and mysqlnd with the only difference that it is only available with mysqlnd.

A comparison of the "before option 'm'" and "after option 'm'" is also included.

What do you do when you have a feature in your Web application that takes longer than a second or two to finish? You need some type of offline processing solution. Check out several methods for offline servicing of long-running jobs in your PHP application.

He talks about cron and its role in offline processing (including a basic primer on its format) before getting into the example itself. He looks at three examples:

• building an email queue
• building a generic queue system
• dumping out the database
