So, this will cause an exception: $a = 2; $f = function($i) { return $i + $a; } $f(1); […] Read more – ‘PHP Closures’.

These will focus on the technical details of developing web sites and applications so will probably be interesting to only a subset of readers. Within the next few months, time permitting, we will be […] Read more – ‘From the Laboratory: Image Resizing and Thumbnail Creation’.
