This is the line of code that it reference to.

 

$file_ext = strtolower(end(explode(".", $file_name)));

 

Can someone please help me

end expects an actual array variable as a parameter -

 

The array. This array is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.

 

You need to assign the result of the explode() statement to a program variable and then supply that as the parameter to the end() statement.
