A revised better alternative for fnmatch on windows. It should work well on PHP >= 4.0.0
<?php
if (!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
return @preg_match(
'/^' . strtr(addcslashes($pattern, '/\\.+^$(){}=!<>|'),
array('*' => '.*', '?' => '.?')) . '$/i', $string
);
}
}
?>
fnmatch
(PHP 4 >= 4.3.0, PHP 5)
fnmatch — Match filename against a pattern
Description
bool fnmatch ( string $pattern, string $string [, int $flags] )fnmatch() checks if the passed string would match the given shell wildcard pattern.
This 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.
Example 627. Checking a color name against a shell wildcard pattern.
<?php
if (fnmatch("*gr[ae]y", $color)) {
echo "some form of gray ...";
}
?>
Warning
For now this function is not available on Windows or other non-POSIX compliant systems.
See also glob(), ereg(), preg_match() and the Unix manpage on fnmatch(3) for flag names (as long as they are not documented here ).

soywiz's function didnt seem to work for me, but this did.
<?php
if(!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
return preg_match("#^".strtr(preg_quote($pattern, '#'), array('\*' => '.*', '\?' => '.'))."$#i", $string);
} // end
} // end if
?>

A better "fnmatch" alternative for windows that converts a fnmatch pattern into a preg one. It should work on PHP >= 4.0.0
<?php
if (!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
return @preg_match('/^' . strtr(addcslashes($pattern, '\\.+^$(){}=!<>|'), array('*' => '.*', '?' => '.?')) . '$/i', $string);
}
}
?>

The last line of soywiz at gmail dot com windows replacement should be changed to:
return preg_match('/' . $npattern . '$/i', $string);
otherwise, a pattern for *.xml will match file.xml~ or any else anything with the text *.xml in it, regardless of position.

A "fnmatch" alternative that converts the pattern, to a valid preg one and uses preg_match then. It will work on windows.
<?php
if (!function_exists('fnmatch')) {
function fnmatch($pattern, $string) {
for ($op = 0, $npattern = '', $n = 0, $l = strlen($pattern); $n < $l; $n++) {
switch ($c = $pattern[$n]) {
case '\\':
$npattern .= '\\' . @$pattern[++$n];
break;
case '.': case '+': case '^': case '$': case '(': case ')': case '{': case '}': case '=': case '!': case '<': case '>': case '|':
$npattern .= '\\' . $c;
break;
case '?': case '*':
$npattern .= '.' . $c;
break;
case '[': case ']': default:
$npattern .= $c;
if ($c == '[') {
$op++;
} else if ($c == ']') {
if ($op == 0) return false;
$op--;
}
break;
}
}
if ($op != 0) return false;
return preg_match('/' . $npattern . '/i', $string);
}
}
?>

you couls also try this function that I wrote before I found fnmatch:
function WildToReg($str)
{
$s = "";
for ($i = 0; $i < strlen($str); $i++)
{
$c = $str{$i};
if ($c =='?')
$s .= '.'; // any character
else if ($c == '*')
$s .= '.*'; // 0 or more any characters
else if ($c == '[' || $c == ']')
$s .= $c; // one of characters within []
else
$s .= '\\' . $c;
}
$s = '^' . $s . '$';
//trim redundant ^ or $
//eg ^.*\.txt$ matches exactly the same as \.txt$
if (substr($s,0,3) == "^.*")
$s = substr($s,3);
if (substr($s,-3,3) == ".*$")
$s = substr($s,0,-3);
return $s;
}
if (ereg(WildToReg("*.txt"), $fn))
print "$fn is a text file";
else
print "$fn is not a text file";
