note 116284 added to debugger

p_r() is a function for logging variable values. In this example the function p_r() does only log when the URL parameter d=<nonzero> is set. Reset it by d=0. When the parameter is a valid filename (relative to the script's path) it will be logged to that file rather than to the browser. [code] @session_start(); // debug if (isset($_GET['d'])) { $_SESSION['d'] = $_GET['d']; } if (@$_SESSION['d']) { function p_r($exp) { $res = ""; $trace = debug_backtrace(); $level = 0; $e = error_reporting(E_ALL&~E_NOTICE); $file = strrpos($trace[$level]['file'], "/"); $file = substr($trace[$level]['file'],$file+1); $line = date("H:i:s"). " " . $file . ' ' . $trace[$level]['line'] . ' ' . $trace[$level+1]['function'] . "()"; $e = error_reporting($e); if (!is_string($exp)) $exp = var_export($exp,1); if (substr($_SESSION["d"],-4)==".log") { file_put_contents ($_SESSION["d"],$line . ": ". $exp . "\n", FILE_APPEND); } else { $res = $line . "\n<pre>".htmlentities($exp). "</pre>\n"; echo $res; } return $res; } // refresh to prevent timeout $a = $_SESSION['d']; $_SESSION['d'] = $a; error_reporting (E_ALL); } else { function p_r() {} } // end if debug [/code] ---- Server IP: 72.52.91.14 Probable Submitter: 46.165.210.17 ---- Manual Page -- http://php.net/manual/en/debugger.php Edit -- https://master.php.net/note/edit/116284 Del: integrated -- https://master.php.net/note/delete/116284/integrated Del: useless -- https://master.php.net/note/delete/116284/useless Del: bad code -- https://master.php.net/note/delete/116284/bad+code Del: spam -- https://master.php.net/note/delete/116284/spam Del: non-english -- https://master.php.net/note/delete/116284/non-english Del: in docs -- https://master.php.net/note/delete/116284/in+docs Del: other reasons-- https://master.php.net/note/delete/116284 Reject -- https://master.php.net/note/reject/116284 Search -- https://master.php.net/manage/user-notes.php
