] )
fnmatch() checks if the passed string would
match the given shell wildcard pattern.
Parameters
-

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
flagscan be any combination of the following flags, joined with the binary OR (|) operator.A list of possible flags for fnmatch() FlagDescription FNM_NOESCAPEDisable backslash escaping. FNM_PATHNAMESlash in string only matches slash in the given pattern. FNM_PERIODLeading period in string must be exactly matched by period in the given pattern. FNM_CASEFOLDCaseless match. Part of the GNU extension.
