parsing a string for keywords

[bill]

I need to parse a set of directory entries (of photo image files)
and pull out the names of the subjects, which is in the filename.

A file name could contain 1 or more subject names from a limited
set of 18 possibilities.

eg: the possibilities might be: Aoife, Alana, Liam, Paddy.....

the file name might be: 0709-Aoife-Alana-DSC12435.jpg

I could do 18 stripos() calls to check for all 18 possibilities,
but I thought I would run it by the more experienced to see if
you can suggest an easier way

thanks in advance.

$possibities = array('foo','bar','baz'........);
$filenameparts = explode('-',$filename);
$matches = array_intersect($filenameparts,$possibities);

$possibities = array('foo','bar','baz'........);
$filenameparts = explode('-',$filename);
$matches = array_intersect($filenameparts,$possibities);

Addendum, if you want a case-insensitive comparison (PHP >= 5):
$matches = array_uintersect($filenameparts,$possibities,'strc asecmp');

You could iterate through your arrays, changing the case of each
element to lower/higher, and then compare with array_intersect. If you
just put strtolower() around the second argument of explode, that
should take care of that array. You could use array_map for the
former.
