使用 jsoup 从 HTML 中提取所有链接的例子

字节顺序记号（英：byte-order mark，BOM）是位于码点 U+FEFF 的统一码字符（"零宽度无断空白"）。当以 UTF-16 或 UTF-32 来将UCS/统一码字符所组成的字串编码时，这个字符被用来标示其字节序。它常被用来当做标示文件是以 UTF-8 、 UTF-16 或 UTF-32 编码的记号。

class cryption {

	function en($str,$key) {
		$ret='';
		$str = base64_encode ($str);
		for ($i=0; $i			$d_str=substr($str, $i, 1);
			$int =ord($d_str);
			$int=$int^$key;
			$hex=strtoupper(dechex($int));
			$ret.=$hex;
		}
		return $ret;
	}

	function de($str,$key) {
		$ret='';
		for ($i=0; $i			$hex=substr($str, $i, 2);
			$dec=hexdec($hex);
			$dec=$dec^$key;
			$ret.=chr($dec);
			$i=$i+2;
		}
		return base64_decode($ret);
