Why can I only open files in C:\\windows when using file_get_contents to open a file?

Question

Why when I use file_get_contents() to open a file, I can only open files in C:\\windows, but not elsewhere. I put the test file somewhere else. I am afraid that it will modify other files in windows.

Answer 1

It can be opened. If it is not in the same directory, you must write the complete path name, not just the file name.
