Whilst trying to setup LDAP authentication for the first time in Zend Framework, I can across this little quirk when passing parameters to Zend_Auth_Adapter_Ldap, namely that I wasn't passing an array even though it was an array (which I checked using Zend_Debug) Basically Zend Framework expects you to have multiple LDAP servers (even if you have alternative failover in place on a single...
Since you can't simply get Imagemagick from a respository and have the legwork done for you, this is a great guide to follow. Once I've got a spare minute I will revise this for Zend Server (CE) as you can skip a few steps with that.
If you need to get access to the column names of a Zend_Db_Table object (filtering a list of column names so that you discard any that don't match up, for example) then as found on StackOverflow you can do the following:
$table->info(Zend_Db_Table_Abstract::COLS);
Which of course works from within the object itself, so you could write a method such as:
Whilst trying to figure out why Zend Server CE wasn't working properly on my Mac (again...) I realised that something was wrong with the version of Apache shipped with OS X. Luckily Chris Oliver found the problem in the Apache control script.
If you are migrating from a single instance of Drupal to a multi-site installation, you may encounter a problem or two along the way in terms of certain things breaking as they aren't where they used to be. Since Drupal is almost solely reliant upon the database during it's bootstrap process, more often than not if something is misconfigured you can end up with the white screen of death (which...

It is not safe to rely on the system's timezone settings.
If you see this thrown at the E_STRICT level by PHP, then you need to let PHP know which timezone the server is currently running in, by either running the following function in PHP:
date_default_timezone_set('Europe/London');
... where Europe/London is a supported timezone or setting it in php.ini:
date.timezone = "Europe/London"
If you want to manipulate a Number Object (variable) to a specific precision or to fixed decimal places, instead of manipulating the Number itself you can use the Number Class conversion Methods such as toFixed and toPrecision and cast the String Objects they return back to Number Objects: pi = Number(Math.PI.toFixed(2)); trace(pi); // 3.14 Not a replacement for a dedicated rounding function for...
Something that has bugged me a few times, but I needed to figure out this time, as a Flash beginner, is that because everything is an object (and thus an instance of a class, including primatives) you more often than not (unless using primitives/statics) bind everything because you're always passing variables by reference.
An ActionScript Compiler bug that I discovered today (that has been open for 5 years according to Adobe! ) whereby a compliation error caused in one timeline script will cascade to another without an appropriate warning as to where it was generated.
