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.

PHP:CSI - Date Is Less Than One Month Ago
Working with logic surrounding dates can sometimes be difficult and it's fairly common to come across really subtle date and time based bugs.

Anyone tell me how to get extension of that file

In the examples above I have used the following to extract the extension of the file.
However, I have not written it this way for a number of years now. My preferred route is to use the pathinfo() function. This will return information about the file name passed to it. For example.
Will print out.
If you want to get *just* the file extension then you pass in the PATHINFO_EXTENSION flag to the pathinfo() function. Like this.
This returns a string instead of the full array of file info, so the function now prints this:
I hope that answers your question?
