计算两个文件的相对路径(php)

方法一:

/** * 计算$path2相对于$path1的路径 * * @param string $path1 * @param string $path2 * @author 陌路烟云 <[e-mail]> * @since 2014-06-13 * @return string */function get_relative_path($path1='', $path2=''){$arr_path1 = explode('/', $path1);$arr_path2 = explode('/', $path2);$intersection = array_intersect($arr_path1, $arr_path2);$pathinfo = str_repeat('../', count($arr_path1)-count($intersection)-1);for( $i = count($intersection); $i <= count($arr_path2)-2; $i++ ){$pathinfo.= $arr_path2[$i].'/';}return $pathinfo;}$a = '/a/b/b/d/e/f.php'; $b = '/a/b/b/12/34/c.php';echo get_relative_path($a,$b);
