Suppose you know how to create plain Dohsa ( Dohsa class) , and you wanted to add flavor to it. You are thinking to prepare MasalaDohsa and OnionDohsa from this plain Dohsa.
So instead of modifying the main Dohsa class, you can add OnionDohsa and MasalaDohsa class which will extend dohsaDecorator class and add the flavor on the main plain Dohsa.

The code uses the glob function to fetch images with specific extensions and then displays the images using HTML.
By using func_get_args(), you can capture and handle any number of parameters passed to a function, making your PHP functions more flexible and versatile.
array_walk() and array_map() both are used to work with the individual array element. array_walk() allows for operations to be performed on each element, but it does not return a new array. Instead, it operates directly on the original array and is typically used for side effects like printing, modifying elements in-place, or other operations where the result is not needed in a new array.
On the other hand, array_map() Returns a new array with modified values.
This guide demonstrates how to use braces to properly nest ternary operators in PHP, ensuring correct evaluation and avoiding common errors with practical example.
In Line 7 and 11 you can see how the first braces are used between the ternary operators which makes the output different.
Continue reading “Exploring Nested Ternary Operations in PHP”Here I will try to show about how to find different elements between arrays using array_diff and array_diff_assoc functions in PHP. This will help you to understand array differentiation based on values and keys.
