It’s generally not a good idea to mess about with error reporting levels – just turn them on while developing and off in production.
However, I recently came across a situation where I wanted to suppress the error notices being generated while developing a particular class.
An autoloader class was generating notices while looking for files – a useful feature as it shows the paths where it wasn’t finding the files, so I didn’t want to change the source of the error notices.
Instead, the solution was to change the error reporting levels in the class using the autoloader using PHP’s error_reporting function. This function returns the previous error reporting level when called, allowing it to be set back later on.
function __construct( \PDO $db, $p = array() )
// Change error reporting level
$this->old_error_reporting_level = error_reporting( E_ERROR | E_WARNING | E_PARSE );
// Change error reporting level back
error_reporting( $this->old_error_reporting_level );
Maybe someone else will find this useful!
I keep having to Google this so thought I’d record it here.

Have just found that you can import a list of choices for dropdown fields in Wufoo.
This is great for long lists of options, for example countries. You can choose from a load of pre-defined lists (which can added to), or paste a list of choices.
All they need to add now is an easy way to share and re-use these customised fields among other forms.
There are a few CSS grid systems out there, some as part of frameworks, some stand alone, most of which use a column system – splitting the overall container width into a number of columns and then using classes like
col-2 to give an element a width equal to 2 columns.
Quite early on in my HTML coding days, I got to grips with percentage widths in CSS so I find these columns a bit too removed from the actual width and the relative dimensions of elements in a design.
Instead, I like using fractional CSS classes to define widths, e.g.
width_half which applies the CSS
width: 50%;, and started re-using these classes in various projects… which led to this mini CSS framework.
It provides classes like
w_1_8 which give an element a width of one half and one eighth of it’s container respectively.
Combined with a border box reset which I first read about here and simple container, row and gutter classes, it makes for a simple and small CSS grid system.
