Unlink
It is used to delete the file used in the context.
Example :
unlink('test.html');
Unset
It is used to unset or destroy the variable.
Example :
unset($var);
If a global variable is attempted to "unset" inside a function, the local variable is destroyed.

In PHP unlink() is a function for file system handling, unlink() is used to delete files (physical).
And unset() is a function for variable management. It will make a variable undefined. Unset () is used to destroy a variable in PHP. In can be used to remove a single variable, multiple variables, or an element from an array.
