Creating Sparklines In PHP
A sparkline is a very small line graph that is intended to convey some simple information, usually in terms of a numeric value over time. They tend to lack axes or other labels and are added to information readouts in order to expand on numbers in order to give them more context.
PHP:CSI - Improving Bad PHP Logging Code
I read The Daily WTF every now and then and one story about bad logging code in PHP stood out to me. The post looked at some PHP code that was created to log a string to a file, but would have progressively slowed down the application every time a log was generated.
Generating Histogram Colour Analysis Graphs From Images In PHP
If you've ever looked at the settings in a digital camera, or have experience with image processing programs like GIMP, then you may have seen a colour histogram. This is a simple graph that shows the amount of different shades of colour are present in the image.
PHP:CSI - To Switch, Or Not To Switch?
I was writing unit tests for a API mapping function recently and came across this interesting issue. The code I was writing tests for was in a legacy codebase that I was making changes to, and it made sense to have some unit tests in there before I started work to ensure everything worked before and after.
Drupal 9: Generating Header Images For Pages Of Content Using PHP
Embedding image within pages of content helps both within the design of the page and when shared on social media. If you set up meta tags to point at a particular image then that image will appear when the page is shared on social media. This makes your page stand out more.

The first loop will return 0 and the second one as 1. reason being, while, first checks the condition and fails and do while, first executes it and then checks the condition.

PermalinkI've got a question about the do while order, what will happen if you rotate it to while do? I am sorry if it sounds like a stupid question I admit I am a beginner and really would like to learn, thank you.

PermalinkHi Daniel,
It's fine to ask questions, especially if you're learning!
So I'm assuming you mean converting the structure to this:
This results in a syntax error as PHP doesn't know what to do with the "do" at the end of the statement. In PHP there is a while loop and a do-while loop, but not a while-do loop.
The question in this post is meant to show the differences between while and do-while, showing that the code in the do-while loop is run at least once, even if the outcome of the while check is false.
I hope that helps a little?
