I’m developing a new PHP file under Windows 10. Each time I run the file (which terminates with an error), the source file disappears. Also somehow its name is blacklisted so I can’t just resave the file with the same name. I have to give it a new name. So if my file is called testfile.php, after I run it there is no file testfile.php, and if I try to resave the file as this name it says I don’t have permission. So I have to resave it as testfile2.php, testfile3.php etc.
Why is this happening?
