PHP Splat Function
One of my favorite MooTools functions is $splat(). Splat takes a given argument and returns an array if the argument is not already an array. This is especially helpful when I've coded my script to cycle through an array of items for processing one at a time.
The PHP Code
function splat($input)
{
return is_array($input) ? $input : array($input);
}
When do I use this? Lets say I have a list of items that I can delete individually or alternatively I can use checkboxes to select many to delete at once. Using splat() will ensure my code works if the user chooses to delete one item individually.

Client-side APIs on mobile and desktop devices are quickly providing the same APIs. Of course our mobile devices got access to some of these APIs first, but those APIs are slowly making their way to the desktop. One of those APIs is the getUserMedia API...

I spent a few months experimenting with different approaches for writing simple, elegant and maintainable media queries with Sass. Each solution had something that I really liked, but I couldn't find one that covered everything I needed to do, so I ventured into creating my...

Let's be honest, form validation with JavaScript can be a real bitch. On a real basic level, however, it's not that bad. HTML5 has jumped in to some extent, providing a few attributes to allow us to mark fields as required or only valid if matching...

Mobile and desktop browser vendors do their best to help us not look like idiots by providing us autocomplete, autocorrect, and autocapitalize features. Unfortunately these features can sometimes get in the way; we don't always want or need the help they provide. Luckily most browsers allow...
Slick!
splat()’s a pretty cool sounding function name, but I still prefer PHP’s explode().
@Will: And the both deal with arrays!
David,
I see you writing (if) statements in a unique way that looks a lot cleaner…me being OCD I am really into this idea…can you explain more in depth the basics of writing an if statement this way…preferably an example of an if, else, and else if…that would be awesome.
Thanks,
Seth
@Seth: Do a site search for “ternary.” That will get you all of my articles on the topic.
You can also use typecasting:
$a = (array) $b;instead of$a = splat($b);I agree with Bob and usually use typecasting for this sort of things.
There are small differences, however. For example, if you pass an object into splat, you’ll get an object inside of the array. If you typecast an object, you will get an array containing the objects properties. That is one point to typecasting, in my opinion.
Splat, on the other hand, handles null better. If you pass null into splat, you will get a null inside of the array. If you typecast a null, you will get an empty array. This is disappointing because this means there is no way to differentiate between $input being empty and $input being null.
Keep in mind that if you typecast an array, you get the same array, not the same array inside another array.
Therefore, you can get the best of both worlds with the following:
function splat($input)
{
return is_null($input) ? array(null) : (array) $input;
}
Been working with forms a lot lately while I convert some of my flat php stuff to Ajax / Mootools. This is fantastic!
