FNMATCH
Match filename against a pattern
SYNTAX
fnmatch ( string $pattern , string $string [, int $flags = 0 ] ) : bool
PARAMETERS
pattern
The shell wildcard pattern.
string
The tested string. This function is especially useful for filenames, but may also be used on regular strings.
The average user may be used to shell patterns or at least in their simplest form to '?' and '*' wildcards so using fnmatch() instead of preg_match() for frontend search expression input may be way more convenient for non-programming users.
flags
The value of flags can be any combination of the following flags, joined with the binary OR (|) operator.
NUMBER | NAME | DESCRIPTION |
---|---|---|
1 | FNM_PATHNAME | Slash in string only matches slash in the given pattern. |
2 | FNM_NOESCAPE | Disable backslash escaping. |
4 | FNM_PERIOD | Leading period in string must be exactly matched by period in the given pattern. |
16 | FNM_CASEFOLD | Caseless match. Part of the GNU extension. |
RETURN
Returns TRUE if there is a match, FALSE otherwise.
