note 77203 added to function.realpath

Given real paths of two files, this function finds the relative path of one ($dest) with respect to the other ($root). echo rel_path('a/b/c', 'd/e'); // './../../a/b/c' echo rel_path('a/b/c', 'a/b/c/d/e'); // './../..' echo rel_path('a/b/c/d/e', 'a/b/c'); // './d/e' function rel_path($dest, $root = '', $dir_sep = '/') { $root = explode($dir_sep, $root); $dest = explode($dir_sep, $dest); $path = '.'; $fix = ''; $diff = 0; for($i = -1; ++$i < max(($rC = count($root)), ($dC = count($dest)));) { if(isset($root[$i]) and isset($dest[$i])) { if($diff) { $path .= $dir_sep. '..'; $fix .= $dir_sep. $dest[$i]; continue; } if($root[$i] != $dest[$i]) { $diff = 1; $path .= $dir_sep. '..'; $fix .= $dir_sep. $dest[$i]; continue; } } elseif(!isset($root[$i]) and isset($dest[$i])) { for($j = $i-1; ++$j < $dC;) { $fix .= $dir_sep. $dest[$j]; } break; } elseif(isset($root[$i]) and !isset($dest[$i])) { for($j = $i-1; ++$j < $rC;) { $fix = $dir_sep. '..'. $fix; } break; } } return $path. $fix; } ---- Server IP: 203.199.124.111 Probable Submitter: 85.195.119.14 ---- Manual Page -- http://www.php.net/manual/en/function.realpath.php Edit -- https://master.php.net/note/edit/77203 Del: integrated -- https://master.php.net/note/delete/77203/integrated Del: useless -- https://master.php.net/note/delete/77203/useless Del: bad code -- https://master.php.net/note/delete/77203/bad+code Del: spam -- https://master.php.net/note/delete/77203/spam Del: non-english -- https://master.php.net/note/delete/77203/non-english Del: in docs -- https://master.php.net/note/delete/77203/in+docs Del: other reasons-- https://master.php.net/note/delete/77203 Reject -- https://master.php.net/note/reject/77203 Search -- https://master.php.net/manage/user-notes.php
