My Coding Style Today I Change

I admit, I've always been more of a Trekkie than a Star Wars fan. (did I just hear some light sabers firing up?) I mean, there's not even a collective term for Star Wars fans. Calling them "Star Wars fans" seems forced (no pun intended). That said, Yoda has given good advice, on occasion, and I have to think that both he and Spock would approve of the notation named for him.

Determing if an array has duplicate values in PHP

Recently, I had the need to determine whether an array had duplicate values in it. It didn't matter what the duplicate values were, or how many duplicates there were, either of which can be answered with array_count_values(), I just needed to know whether there were any at all; a boolean answer.

There are a lot of ways to approach it, but I found this to be the the most minimal:

$temp_array = array_unique($original_array);
$duplicates = sizeof($temp_array) != sizeof($original_array);

roundDown for php

It seems crazy that php doesn't have a native roundDown function.

It does have round(), which has various modes, but they only provide for rounding down if the starting value is < .5   In some cases, one must round up (the number of boxes needed to hold a quantity of items), but in some, it is necessary to always round down, in particular anywhere that a fraction of something makes no sense because the item is either whole or not.

There are numeric ways to accomplish this, such as:

$rounded_value = floor($value / 10^x) * 10^x

PhpStorm and xdebug in the browser - the missing instruction

I spent the usual two lifetimes getting xdebug working (again) after upgrading to a new major version of phpStorm. Finally, I could debug a standalone php script in the IDE, but all attempts to do so from the browser were fruitless.

It turns out that phpStorm and the browser were using different versions of php.

Things to do (note that I am using Macports):

Using the Correct Ruler

Sometimes, the guys controlling the synapses are asleep at the switch, and things I've always known are momentarily gone. It's one thing when I know that to be the case — knowing what I don't know — such as seeing an actress on the screen and being asked who it is. I knew until I was asked. It's not knowing that I don't know that's the bigger problem...not realizing that I've forgotten, because the switchman hasn't fallen asleep, he's thrown the wrong switch.

The Secret to drupal_add_js

drupal_add_js() doesn't add javascript or jquery to your Drupal page? Let's take a look at why, and how to fix it.

Sometimes we need javascript or jquery in our Drupal page. If the script needs to appear on every page, we could just add it to our page template, but what if we want it only on one page?

We could create a page template for the page on which we want it. If the requirement is static and small, that is a way to do it, though putting the script directly in the template is not the best-practices way to do it, for several reasons.

Why PHP?

languages - J. Ayen Green - Ayen Designs

Whenever I sit down to design the architecture of a new application, I sit back and ponder. For the past few years, my decision continues to be: php.

I have read many blog entries on the merits of choosing php, ruby or java, and theories on why programmers make choices in opposition to the blogger's. It's my turn to weigh in, for what it's worth.
