fnmatch — Match filename against a pattern
$pattern
, string $string
[, int $flags = 0
] )
fnmatch() checks if the passed string would
match the given shell wildcard pattern.
patternThe shell wildcard pattern.
stringThe 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 following flags, joined with the
binary OR (|) operator.
