The Travails of Traversal

13 07 2016

Flickr: By JacobDavis

The venerated foreach-loop may seem to have formed a part of PHP from the outset, but it actually entered the language starting with PHP 4, apparently appropriated from Perl. While nowadays, this control structure provides a convenient way to iterate over an array or object without the complication of conditional looping inherent in for, while, and do-while loops, it was originally intended to provide a way to easily traverse arrays (see PHP Manual published 3-6-2003).

Reaching for the Stars

In 2014, Davey Shafik, author of the Zend PHP 5 Certification Study Guide, presented a proposal to the PHP Internals List recommending the addition of yet another operator, the spaceship. While the operator’s name may connote PHP blasting off, its down-to-earth function scarcely relates to outer space. Read the rest of this entry »





The Erroneous Basis of base_convert()

Some bugs linger from one version of PHP to the next, such as the one associated with base_convert() and other base conversion functions. It has existed at least since the long, gone days of PHP 4. It even managed to escape the notice of Eevee in his encyclopedic rant railing against PHP a few years ago. An understandable oversight, given that nowadays developers usually apply themselves to other endeavors than converting values from one base to another. Read the rest of this entry »





PHP: Classy Dynamics

Devotees of PHP may worry with the debut of PHP 7 that users have lost the beloved language we’ve known over the past twenty years. In truth, the newest version generally conforms to previous ones. In fact, the advent of PHP 7 heralds a technology distinguished by greater flexibility and consistency.

Modulating the Modulo

A recent article contrasting PHP with Ruby, denigrates making comparisons of one language with others, dismissing such efforts as worthless save for being a clickbait strategy. Yet, sometimes the best way to understand the familiar requires venturing out and exploring something new. If one only knows PHP, a developer may still write quality code. But, learning about C, JavaScript and Python, all of which have influenced PHP, may enhance one’s appreciation for its nuances.And, let’s not forget the other “P” in the pod, Perl, which had a pivotal bearing on PHP’s early development. Speaking of Perl, its creator Larry Wall drew inspiration from UNIX. Of particular interest, that operating system’s (OS) Bourne Shell has an open-sourced cousin bash (the “Bourne Again Shell”), knowledge of which may also enhance one’s appreciation for PHP.

While looking forward to the upcoming official release of the latest incarnation of PHP, namely PHP7 (slated for November 12th), spending a moment or two reviewing such basics as the expression statement should enhance one’s appreciation for PHP and how this powerful feature contributes to its feasibility, permitting it to reign more than two decades.

Someone posted an interesting JavaScript question recently at StackOverflow, concerning how one may  convert a date string into Unix time without the timezone effecting the result. In reflecting on that question, I also discovered a “trick” by which one can fool a local date object to a degree.

PHP: Going to Zero

2 12 2014

Flickr: by djniks

Following in the tradition of its predecessor Perl, PHP has its own secret operators (see “Inchworm on a Stick“).Today let’s explore the heretofore unknown PHP operator, “->”, most remarkable for quickly reducing a numerical value to zero.  At first sight, one might mistake this symbol for PHP’s arrow operator designed to access an object’s properties and methods, until one realizes that two hyphens instead of one distinguish this arrow.  So, why have we yet to hear about this new operator? What is its name and why does the operator precedence table (see Manual) neglect to include it?

Elizabeth Barrett Browning pondered affairs of the heart when she penned her famous love poem, a fragment of which entitles this piece as an acknowledgment of PHP’s characteristic TIMTOWTDI (“there is more than one way to do it”) approach, particularly prevalent in displaying data.

One of the earliest ways to do output involved PHP utilizing an echo command written in C for the express purpose of Read the rest of this entry »

Taking Stock of the Stack in PHP

29 03 2014

flickr: by cvfyne

Introduction

You may have heard about ‘the stack’ or call stack, part of a computer’s random access memory (RAM), wherein a function, including its parameters and return value, reside temporarily. One retrieves them on the basis of FILO (First In, Last Out), synonymous with LIFO (Last In, First Out). Users of high-level languages like C and PHP are much less likely to directly handle this stack. Read the rest of this entry »

The WordPress.com stats helper monkeys prepared a 2015 annual report for this blog.

Here's an excerpt:

A New York City subway train holds 1,200 people. This blog was viewed about 5,100 times in 2015. If it were a NYC subway train, it would take about 4 trips to carry that many people.
