I use Phing for a lot of different tasks, it helps me to automate things that I would otherwise mess up if left to my own devices. Prime candidates for Phing scripts are things that I don't do that much and forget how to do them, or that have a number of complex steps. The only problem I have found is that because many of the Phing scripts I create rely on system changes (eg, configuring an Apache server) they therefore require system changing privileges. Normally I would just prefix the Phing command with sudo, but every now and then I forget all about that step and the build fails.
During DrupalCampNW 2012 last November the company we hired to record the sessions also spent some time interviewing the people who attended. From these interviews we were able to create three videos, two from the main event and one about what Drupal means to different people. These videos are now complete so I'm posting them here so everyone can see. I think they came out really well.
I was recently working on a module that contained a content type as a feature. When the module was enabled the hook_install() hook set up a collection of taxonomy terms which were used within the content type as a field. Whilst testing this out I realised that although the terms were installed correctly the default value of the field changed depending on which system the module was installed on. The reason for this was that the term ID was being used to pull out the default term from the database, which is the normal behaviour in Drupal.
Getting the first or last item from an array in PHP is usually quite easy. If you create an array and then add a bunch of values to it then the array index will increment by 1 for every element you add. This means that in order to get the first element from an array you just reference the default stating position (0). To get the last item in the array the index key will be the length of the array, minus 1. Here is some example code showing this.
Alternative PHP Cache (APC) is an opcode and variable cache for PHP. When you run a PHP script it is first compiled into a series of opcodes which are then used by the Zend engine to run the program before being discarded. APC sits between the source files and the Zend engine and will stop the opcodes generated during the PHP script execution being thrown away. This means that when you run a PHP script a second time the work done in generating the opcodes has already been done and the script will execute faster.
I recently have started looking into making myself a PHP Zend Certified Engineer and after doing a bit of research I found that the standard PHP string and array functions appear to be a large part of the exam material. So as a starting point (and for future revision) I decided it might be a good idea to create a revision sheet for those functions.
