note 82010 added to function.realpath

my relative-path function, not smallest but was very usefull for me. <?php function relativepath($dest_realpath = null) { if (is_null($dest_realpath)) $dest_realpath = realpath(dirname(__FILE__)); else $dest_realpath = realpath($dest_realpath); if (!file_exists($dest_realpath)) return false; $file = substr($dest_realpath, strrpos($dest_realpath, '/') + 1); $dest = substr($dest_realpath, 0, strrpos($dest_realpath, '/') + 1); $curr = getcwd() . '/'; $similar_func = create_function('$x,$y,$z', '$str = strlen($x) > strlen($y) ? array($x, $y) : array($y, $x); list($str1, $str2) = $str; $r = ""; for($i=0;$str1[$i];$i++){ if ($str1[$i] != $str2[$i]) break; $r .= $str1[$i]; }; $r = substr($r, 0, strrpos($r, $z)); return empty($r) || $r == $z ? null : $r;'); $similar = $similar_func($curr, $dest, '/'); if ($similar) { $back = substr_count(str_replace($similar, '', $curr), '/') - 1; $dest = str_repeat('../', $back) . str_replace($similar . '/', '', $dest); } else { $dest = str_repeat('../', substr_count($curr, '/') - 1) . substr($dest, 1); } return $dest . $file; } echo relativepath(dirname(__FILE__) . '/../test/example.php'); ?> ---- Server IP: 69.147.83.197 Probable Submitter: 201.68.33.181 ---- Manual Page -- http://www.php.net/manual/en/function.realpath.php Edit -- https://master.php.net/note/edit/82010 Del: integrated -- https://master.php.net/note/delete/82010/integrated Del: useless -- https://master.php.net/note/delete/82010/useless Del: bad code -- https://master.php.net/note/delete/82010/bad+code Del: spam -- https://master.php.net/note/delete/82010/spam Del: non-english -- https://master.php.net/note/delete/82010/non-english Del: in docs -- https://master.php.net/note/delete/82010/in+docs Del: other reasons-- https://master.php.net/note/delete/82010 Reject -- https://master.php.net/note/reject/82010 Search -- https://master.php.net/manage/user-notes.php
