• PHP date localisation with setlocale July 20, 2015

  Localising sites can be a chore, but PHP has the venerable setlocale() to use system locales. These are like templates or profiles that describe how various types of data should be displayed. Should a price have a comma or point to indicate the decimals? When printing a date should PHP output Monday or Montag? All of these considerations are locale specific and they map to a geographical area. Various cultures have their own standards for displaying this kind of information not to mention different languages to accommodate. Read more ⇒

• Simultaneously benchmark many URLs with ApacheBench and GNU parallel June 25, 2015

  Once in a while you come across situations where someone wants to know what a server can do or how many requests it can handle under a realistic load scenario. It could simply be that you want to hit a large selection of sites or even that you want to simultaneously hit a number of different pages on the same site. In my case I am testing the performance of a Drupal multisite installation where one core set of code is shared by many sites on different URLs. Read more ⇒

• Memoization or function cache May 18, 2015

  A little known feature of PHP’s static keyword is that it allows for memoization or function caching. This is a process whereby a functions heavy lifting can be cached so that subsequent calls are faster. It is possible to store any value in a memoized way such as arrays or even objects. This is done without any external side effects - that is to say that the code calling the function will require no changes to support memoization. Read more ⇒

• PHP Function Objects April 16, 2015

  It is possible to treat a class instance as a function in PHP. Quite often this is referred to as a functor even though it should really be known as a function object. This is because functions actually serve a different role in languages that support their use. The convenience of having a reusable function that can be overloaded and carry a context is something to weigh up against using functions or closures. Read more ⇒

• HHVM vs Zephir vs PHP: The showdown February 28, 2014

  Since its inception the slow running speed of PHP has been widely publicised and over the years there have been a number of improvements. The first Zend Engine arrived with PHP4 and delivered various performance enhancements (among other features). Each release since this time has delivered some sort of increased efficiency in one way or another. It has become more interesting recently however with three projects looking for improvements in different ways. Read more ⇒

• Speaking about Functional PHP at BrightonPHP and PHP Hampshire January 9, 2014

  I have been invited to speak at both the upcoming meetings of BrightonPHP and PHP Hampshire about functional programming. This is off the back of the site I created for my (soon to be released) book tentatively entitled Functional Programming in PHP. To get a better idea of what the talk will include I have prepared an abstract: In the PHP world functions are generally sneered at due to their simplicity and perceived as an evil side effect of spaghetti code.

• Add a duration or interval to a date January 3, 2014

  In PHP you can easily add a duration to a DateTime instance in a number of ways. I will review the most common methods for completing the task starting with those available on the DateTime object itself. If you are running PHP 5.2 then the only way to achieve this is to call the modify method. This allows you to pass in a date format, but in this case we are most interested in the relative formats.
