php check if file exist: check only portion

Question

in php we can check if file exist using

if(file_exists("destination/"))
{
    condition
}

but what I wanted to do is...

for example I already have this file on my destination

hello_this_is_filename(2).doc

how would I know if there is a file in that directory having a name containing a character

hello_this_is_filename

I wanted to search that way because... if there is exists on that directory, what will I do is... renaming the file into

hello_this_is_filename(3).doc

I also need to count the existence of my search so I know what number I'm going to put like

(3), (4), (5) and so on

any help?

Use glob.

if (count(glob("destination/hello_this_is_filename*.doc"))) {
  //...
}
