SimpleXML with all of it’s faults is still a great way to interact with XML. Most of it’s shortcomings are related to debugging and how it handles invalid XML is no exception. Let’s take a look at what happens when we load an invalid XML string: $xml = " <?xml

I think one of my biggest gripes with adopting that TDD life is that I feel I’m in the minority with my friends even though the concept appears to be quite mainstream these days. One of the common pushbacks I receive is that it’s hard to write unit tests for

I love hosting my blog on GitHub by way of Jekyll but the Liquid templating system is far from a robust scripting language in my opinion. With the rise of Medium, I’ve been seeing the read time on more and more articles and figured it was time to add the

Fizz buzz is a fairly common screening question to help sniff out non-programmers during the interview process. The task is to print out numbers 1 through 100 but for multiples of 3 print out “Fizz” instead of the number and for multiples of 5 print “Buzz” instead. If the number

I’ve been doing a lot of API integration recently and cURL ends up being exceptionally handy when you are POSTing to an endpoint. Fortunately using cURL in PHP is really easy: // Sets our destination URL $endpoint_url = 'https://somesite.com/path/to/endpoint'; // Creates our data array that we want to post to

Looping through a date range isn’t as simple as looping through an array with foreach but it doesn’t take much additional code to get the job done. To loop through a date range you will need to use a loop (I prefer a while loop) and increment the date by

The topic of break and continue came up the other day and I thought it would make for a good blog post. You’re probably familiar with break moreso than continue because it is part of a switch statement’s syntax. Both break and continue can also be used inside of looping

PHP is a C-style language and thus uses fancy braces to wrap or hug control structures. PHP is also a language that is extremely flexible so you can also get by without using fancy braces. You will never get away from them entirely as functions and classes / class methods

SimpleXML is pretty much the de facto standard for dealing with XML in PHP. The biggest problem with SimpleXML is that it is a pseudo-object that you can’t print_r() or var_dump() to see what’s going on. I recently ran into a situation where it would have been super nice to

We recently discussed parsing XML with SimpleXML and since that writing I ran into a situation where I needed to parse a SOAP response. As it turns out, SOAP responses are a totally different beast when it comes to parsing them with SimpleXML. SOAP responses contain namespaces on some if

On this 238th anniversary of the United States of America, I felt it appropriate to post an article on how to determine what day the July 4th National Holiday is observed on. There are two rules to the observances. First, if the holiday falls on a Saturday, it is observed

Full disclosure, I don’t actually have a staging server for my personal projects. I develop locally in a very similar environment as my production server and any time I have to do something major, like upgrading the OS or upgrading software between major revisions, I always do a dry run

Parsing XML in PHP couldn’t be easier thanks to the SimpleXML extension. SimpleXML allows you to read in an XML string, verify that it is in fact XML and can create an object that you can interact with by way of the node names in the XML.The SimpleXML extension also

I have an upcoming freelance project coming up that includes checking an IMAP email account as well as working with XML in PHP. Let’s talk about connecting to an IMAP account in PHP, don’t worry, I’ll discuss parsing XML next week ;) For the sake of example, we’re going to

A little late on the Mother’s Day part, but since today is Father’s Day, I figured it would be fun to discuss how to obtain the dates for these moving holidays. To do so, all we need to use is use strtotime and tell it when the holiday will occur

This post was supposed to be a discussion of my migration back to Android from iOS but direction changed yesterday morning. At 9:30 am I found myself in the middle of a DDoS attack that was affecting the rack my server lives on. My sites slowed to a crawl and

Have you ever run into a scenario where you have to loop through a set of data and perform database queries for each iteration? Obviously we shouldn’t run them one by one, so we end up using a TRANSACTION or even just building out one large query in the case

You are probably already familiar with $_GET, $_POST and $_REQUEST but what about $_PUT? Trick question, $_PUT (as well as as $_HEAD and $_DELETE) doesn’t exist in PHP at this time. Never fear! We can create a $_PUT array with the following code: if ($_SERVER['REQUEST_METHOD'] == 'PUT') { parse_str(file_get_contents("php://input"), $_PUT);

I’ve been taking a lot of programming tests / challenges recently as I was in the market for a new [and hopefully exciting] opportunity to spend my time on. Because of this, I am full of new blog post ideas based on the questions / challenges asked. This week I’m

I tend to shy away from these self gratifying posts about my own open source contributions, but I’m going to make the exception because this particularly library has been receiving quote a few downloads this month. I’m unsure for the increase, but my Google Places PHP Library has had over

If you know me then you know I fucking adore Redis. Over the last few years it’s slowly worked it’s way into the majority of the things I have built. Unfortunately, recently I ran into a problem that Redis could easily accomplish but would require more RAM than I have

Today I went on a mission to find a PHP function that I’ve never used before and knew nothing about. The mission was such a success that I have two functions to discuss and honestly, I’m pretty sure I’ll never use them. That being said, if the need ever arises

I’ve discussed the use of preg_replace_callback in the past in regard to passing variables to anonymous functions but never touched on how to use preg_replace_callback or the fact that the /e modifier has been deprecated in PHP 5.5+. Even though /e still works in PHP 5.5 in the near future

PHP Data Objects (PDO) is arguably the best database abstraction layer available in PHP. It provides a consistent interface across multiple datasources (MySQL, PostgreSQL, et cetera) and helps boost your site’s security by way of prepared statements. It even supports transactions which we’ll be taking a look at here. Database

Hi, my name is Josh and I am a Vim addict. I have been for quite a while now, nearly 15 years by my estimates. I love everything about it but in all honesty, I have only really started to get “good” with it in the last couple of years.
