FNMATCH(3)								 1								FNMATCH(3)

fnmatch - Match filename against a pattern

SYNOPSIS
       bool fnmatch (string  $pattern, string  $string, [int  $flags])

DESCRIPTION
       fnmatch(3) checks if the passed $string would match the given shell wildcard $pattern.

PARAMETERS
	      o $pattern
		- The shell wildcard pattern.

	      o $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(3)  instead	of
		preg_match(3) for frontend search expression input may be way more convenient for non-programming users.

	      o $flags
		- The value of $flags can be any combination of the following flags, joined with the binary OR (|) operator.
