An enum, or enumeration, is a data type that consists of a set of named values. In PHP, enums allow you to create a fixed set of constants representing a specific data type. The primary purpose of enums in PHP is to provide a convenient way to define a set of related constants representing a…
I am not a big fan of the “Try Catch” syntax in PHP, but in some cases, it is necessary. This is a way of capturing exceptions in a section of code and gives you complete control over what to do. The basic syntax is: I find the code gets messy and hard to understand…
Beyond Compare is a legendary piece of software that I have been using for at least ten years. It compares files and folders with an easy-to-use interface and plenty of advanced features. I have used it to manually check code/version changes, organise photos, efficiently transfer files, and much more. For old-school web development, the FTP…
This shorthand syntax is a nice and simple way to increase or decrease an integer variable by 1: And for subtracting: You may know this already, but there is a bit more to these operators when working with strings that you might not be aware of: It gets even more interesting… See more examples in…
PHP has developed into a more strictly typed language in recent years. Type Declarations help with that and are a fairly new addition to PHP, with recent releases improving them further. They give you more precise, concise code, clarity, validation, type-hinting and more. But first… what are Type Declarations? Take a look at this example:…
JavaScript can be a frustrating language. Tame this beast with these tips and tricks.
If you have come to JavaScript from a background in Java or C, you will like the variation on the “for loop“. It is similar to the “for loop” in Perl, Python or PHP but with a little twist. You can use a for loop to repeatedly run a block of code or once for…
One of the key concepts of JavaScript is the keyword this, which signifies the JavaScript context object. If you write an inner function, you can access any local variables you define in the outer function exactly as if you had defined them locally. You can also access any arguments you pass to a function as if…
It is possible to define multiple functions with the same name in JavaScript, and the last one you define will be the one that runs. This is unlike other languages, where you can distinguish between functions by using a different number of arguments when you call the function. Most programmers will only think about this…
JavaScript allows the use of anonymous functions with full closures. Functions are objects, and you can pass them as arguments like any other object. The scope of a function includes all the names in the scope where it was declared. As you declare functions at run time and local variables can remain after the function…
