fnmatch - Match filename against a pattern
Manual
Code Examples

fnmatch( string$pattern, string$filename, [int$flags = 0] ): bool

fnmatch checks if the passed filename would match the given shell wildcard pattern.

Parameters

pattern

The shell wildcard pattern.

filename

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.

FNM_CASEFOLD Caseless match. Part of the GNU extension.

Return Values

Returns true if there is a match, false otherwise.

For now, this function is not available on non-POSIX compliant systems except Windows.
