note 118071 added to function.print-r

This is an update from Matt's print_r_reverse() solution that works not only with Arrays, but also with stdClass objects. I expect someone finds it useful. <?php function print_r_reverse($in) { $lines = explode("\n", trim($in)); if ( (trim($lines[0]) != 'Array') && (trim($lines[0]) != 'stdClass Object') ){ // bottomed out to something that isn't an array or object return $in; } else { // this is an array or stdClass object, lets parse it if (preg_match("/(\s{4,})\(/", $lines[1], $match)) { // this is a tested array/recursive call to this function // take a set of spaces off the beginning $spaces = $match[1]; $spaces_length = strlen($spaces); $lines_total = count($lines); for ($i = 0; $i < $lines_total; $i++) { if (substr($lines[$i], 0, $spaces_length) == $spaces) { $lines[$i] = substr($lines[$i], $spaces_length); } } } $class = trim( $lines[0] ); array_shift($lines); // Array or stdClass Object array_shift($lines); // ( array_pop($lines); // ) $in = implode("\n", $lines); // make sure we only match stuff with 4 preceding spaces (stuff for this array and not a nested one) preg_match_all("/^\s{4}\[(.+?)\] \=\> /m", $in, $matches, PREG_OFFSET_CAPTURE | PREG_SET_ORDER); $pos = array(); $previous_key = ''; $in_length = strlen($in); // store the following in $pos: // array with key = key of the parsed array's item // value = array(start position in $in, $end position in $in) foreach ($matches as $match) { $key = $match[1][0]; $start = $match[0][1] + strlen($match[0][0]); $pos[$key] = array($start, $in_length); if ($previous_key != '') $pos[$previous_key][1] = $match[0][1] - 1; $previous_key = $key; } // behave differently depending on the type switch( $class ){ case 'Array': $ret = array(); foreach ($pos as $key => $where) { // recursively see if the parsed out value is an array/object too $ret[$key] = print_r_reverse(substr($in, $where[0], $where[1] - $where[0])); } break; case 'stdClass Object': $ret = new stdClass(); foreach ($pos as $key => $where) { // recursively see if the parsed out value is an array/object too $ret->$key = print_r_reverse(substr($in, $where[0], $where[1] - $where[0])); } break; default: throw new Exception( 'Type not allowed' ); } return $ret; } } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 84.127.239.199 ---- Manual Page -- http://php.net/manual/en/function.print-r.php Edit -- https://master.php.net/note/edit/118071 Del: integrated -- https://master.php.net/note/delete/118071/integrated Del: useless -- https://master.php.net/note/delete/118071/useless Del: bad code -- https://master.php.net/note/delete/118071/bad+code Del: spam -- https://master.php.net/note/delete/118071/spam Del: non-english -- https://master.php.net/note/delete/118071/non-english Del: in docs -- https://master.php.net/note/delete/118071/in+docs Del: other reasons-- https://master.php.net/note/delete/118071 Reject -- https://master.php.net/note/reject/118071 Search -- https://master.php.net/manage/user-notes.php
