fnmatch() checks if the passed string would match the given shell wildcard pattern .
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 ereg() or preg_match() for frontend search expression input may be way more convenient for non-programming users.
flags
See the Unix manpage on fnmatch(3) for flag names (as long as they are not documented here).
Return Values
Returns TRUE if there is a match, FALSE otherwise.
Examples
Example #1 Checking a color name against a shell wildcard pattern
<?php if (fnmatch("*gr[ae]y", $color)) { echo "some form of gray ..."; } ?>
Notes
