// deprecated // list($username, $password) = explode(',', $myString); $username = explode('=', $username); $username = str_replace('+', ' ', $username[1]); $password = explode('=', $password); $password = $password[1]; // new version, independent of order // $pairs = explode(',', $myString); foreach($pairs as $pair){ list($key, $value) = explode('=', $pair); $results[$key] = str_replace('+', ' ', $value); } // $results['user'] // $results['pass']C. parse_str。我建议这个，这可能是最好的选择。parse_str(str_replace(',', '&', $myString), $results);肉簧咸缮
if(preg_match('/^user=(.+?),pass=(.+?)$/', $myString, $matches)){// if there's no match, this won't be executed $username = $matches[1]; $password = $matches[2]; }。例如，您知道密码只包含字符a-z（仅小写）和0-9，您应该将第二个（。+？）替换为。如果您甚至知道它是固定长度，在MD5哈希的情况下，您应该将替换为{32}
