Strict Standards: Only variables should be passed by referen
Posted: Tue Apr 16, 2013 1:10 pm
This code works as intended( thanks in part to people in this forum) but I keep getting this warning.
Strict Standards: Only variables should be passed by reference in C:\xampp\htdocs\dpSite\new_upload.php on line 20
this is the script:
line 20 $extension = end(explode(".", $_FILES["file"]["name"])); is the one that was cited in the warning message.
Is it telling me that $extension should be passed by value and if so how would I do that?
