note 121039 added to function.print-r

A slight amendment to Matt's awesome print_r_reverse function (Thank You, a life-saver - data recovery :-) . If the output is copied from a Windows system, the end of lines may include the return character "\r" and so the scalar (string) elements will include a trailing "\r" character that isn't suppose to be there. To resolve, replace the first line in the function with... <?php $lines = preg_split('#\r?\n#', trim($in)); ?> This will work for both cases (Linux and Windows). I include the entire function below for completeness, but all credit to Matt, the original author, Thank You. <?php //Author: Matt (http://us3.php.net/print_r) function print_r_reverse($in) { $lines = preg_split('#\r?\n#', trim($in)); if (trim($lines[0]) != 'Array') { // bottomed out to something that isn't an array return $in; } else { // this is an array, lets parse it if (preg_match("/(\s{5,})\(/", $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], $spaces_length); } } } array_shift($lines); // Array 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; } $ret = array(); foreach ($pos as $key => $where) { // recursively see if the parsed out value is an array too $ret[$key] = print_r_reverse(substr($in, $where[0], $where[1] - $where[0])); } return $ret; } } ?> ---- Server IP: 216.194.115.244 Probable Submitter: 51.6.76.104 ---- Manual Page -- http://php.net/manual/en/function.print-r.php Edit -- https://master.php.net/note/edit/121039 Del: integrated -- https://master.php.net/note/delete/121039/integrated Del: useless -- https://master.php.net/note/delete/121039/useless Del: bad code -- https://master.php.net/note/delete/121039/bad+code Del: spam -- https://master.php.net/note/delete/121039/spam Del: non-english -- https://master.php.net/note/delete/121039/non-english Del: in docs -- https://master.php.net/note/delete/121039/in+docs Del: other reasons-- https://master.php.net/note/delete/121039 Reject -- https://master.php.net/note/reject/121039 Search -- https://master.php.net/manage/user-notes.php
