What’s the difference between unset() and unlink()
These two PHP functions are identical on performing some undo operations but differ in the type of data on which they are applied to perform such undo functionalities.
Basically unlink is used in file management in PHP. For example, you have uploaded a file, and you have to delete that file from the PHP code then you can use the unlink function to delete that file. While unset is used for variable and array. For example, you have undefined the variable, you can use an unset function or you can also undefined any particular index of an array using the unset function
