What is the preferred method with php to test and see if a file
[pattern] exists?
For example, i only need to search in one directory, that may have any
number of files named such as afile1.txt, afile2.txt, afile3.txt,
.... And also, bfile1.txt, bfile2.txt, bfile3.txt, ...
I want to see if any such file 'family' exists. That is, i want to
see if there is any file named bfile[1-9][0-9]+.txt. I don't care
which bfile number exists, i just want to know if any bfile exists.
I hope this is clear enough, if not let me know.

After some more research it seems my options are:
1) loop through the directory contents
2) use scandir (then search the resulting array)
3) use glob. I am not familiar with the glob pattern library, it does
not seem like i have the full power of regex when using glob is this
correct? Also, searching the whole filesystem seems...overkill.
What do you suggest, is there a 4th option?
