Possible flags (scratched out of fnmatch.h):
...::...
FNM_PATHNAME:
> Slash in $string only matches slash in $pattern.
FNM_PERIOD:
> Leading period in $string must be exactly matched by period in $pattern.
FNM_NOESCAPE:
> Disable backslash escaping.
FNM_NOSYS:
> Obsolescent.
FNM_FILE_NAME:
> Alias of FNM_PATHNAME.
FNM_LEADING_DIR:
> From fnmatch.h: /* Ignore `/...' after a match. */
FNM_CASEFOLD:
> Caseless match.
Since they’re appearing in file.c, but are not available in PHP, we’ll have to define them ourselves:
<?php
define('FNM_PATHNAME', 1);
define('FNM_PERIOD', 4);
define('FNM_NOESCAPE', 2);
define('FNM_FILE_NAME', FNM_PATHNAME);
define('FNM_LEADING_DIR', 8);
define('FNM_CASEFOLD', 16);
?>
I didn’t test any of these except casefold, which worked for me.
