這裡有一個完善的解決方案,它支援否定字元類別和四個已記錄的旗標。
<?php
if (!function_exists('fnmatch')) {
define('FNM_PATHNAME', 1);
define('FNM_NOESCAPE', 2);
define('FNM_PERIOD', 4);
define('FNM_CASEFOLD', 16);
function fnmatch($pattern, $string, $flags = 0) {
return pcre_fnmatch($pattern, $string, $flags);
}
}
function pcre_fnmatch($pattern, $string, $flags = 0) {
$modifiers = null;
$transforms = array(
'\*' => '.*',
'\?' => '.',
'\[\!' => '[^',
'\[' => '[',
'\]' => ']',
'\.' => '\.',
'\\' => '\\\\'
);
if ($flags & FNM_PATHNAME) {
$transforms['\*'] = '[^/]*';
}
if ($flags & FNM_NOESCAPE) {
unset($transforms['\\']);
}
if ($flags & FNM_CASEFOLD) {
$modifiers .= 'i';
}
if ($flags & FNM_PERIOD) {
if (strpos($string, '.') === 0 && strpos($pattern, '.') !== 0) return false;
}
$pattern = '#^'
. strtr(preg_quote($pattern, '#'), $transforms)
. '$#'
. $modifiers;
return (boolean)preg_match($pattern, $string);
}
?>
這可能需要進一步測試,但它似乎與原生 fnmatch 的實作功能相同。
