I have posted this in debug_print_backtrace() as well but I thought I would put it here because it
applies to both functions really:
Most methods of getting the backtrace and printing are susceptible to a certain runtime flaw.
If the user is able to produce 100+ errors this will throw an error (max reportable error limit size
reached) which in turn will throw 100+ errors on each nest of get_args() creating an infinite loop
and eventually downing your server.
If you are looking for a simple backtrace that (so far) will not fall to this error then use this:
foreach(debug_backtrace() as $k=>$v){
if($v['function'] == "include" || $v['function'] ==
"include_once" || $v['function'] == "require_once" ||
$v['function'] == "require"){
$backtracel .= "#".$k."
".$v['function']."(".$v['args'][0].") called at
[".$v['file'].":".$v['line']."]<br />";
}else{
$backtracel .= "#".$k." ".$v['function']."() called at
[".$v['file'].":".$v['line']."]<br />";
}
}
