note 125237 added to function.debug-print-backtrace

If your show your error messages in HTML (with suitable safety using entities), this function won't work nicely because it uses newlines for formatting. Here is a function that works similarly, but using <BR> tags. Insert it near the beginning of your program to add a stack to Warning output only, or modify it as you like: // Here is code for error stack output in HTML: function error_handler_callback($errno,$message,$file,$line,$context) { if ($errno === E_WARNING) echo "Stack, innermost first:<br>".nl2br((new Exception())->getTraceAsString()); return false; // to execute the regular error handler } set_error_handler("error_handler_callback"); ---- Server IP: 45.112.84.4 Probable Submitter: 103.51.166.36 (proxied: 98.2.238.89) ---- Manual Page -- http://php.net/manual/en/function.debug-print-backtrace.php Edit -- https://master.php.net/note/edit/125237 Del: integrated -- https://master.php.net/note/delete/125237/integrated Del: useless -- https://master.php.net/note/delete/125237/useless Del: bad code -- https://master.php.net/note/delete/125237/bad+code Del: spam -- https://master.php.net/note/delete/125237/spam Del: non-english -- https://master.php.net/note/delete/125237/non-english Del: in docs -- https://master.php.net/note/delete/125237/in+docs Del: other reasons-- https://master.php.net/note/delete/125237 Reject -- https://master.php.net/note/reject/125237 Search -- https://master.php.net/manage/user-notes.php
