note 92713 added to function.debug-backtrace

Maybe it can be useful ... :) <? function IsRecursiveCall() { $ret=false; $cc=debug_backtrace(); $thisfunction=array_shift($cc); if ($callerfunction=array_shift($cc)) { $name=$callerfunction["function"]; reset($cc); while ($cx=each($cc)) if ($ret=($cx["value"]["function"]==$name)) break; } return $ret; } function GetRecursiveCallLevel() { $ret=0; $cc=debug_backtrace(); $thisfunction=array_shift($cc); if ($callerfunction=array_shift($cc)) { $name=$callerfunction["function"]; reset($cc); while ($cx=each($cc)) if ($cx["value"]["function"]==$name) $ret++; } return $ret; } // -- example -------------------------- function RecursiveFunction() { echo "Recursive function begin.\n"; $level=GetRecursiveCallLevel(); echo "Recursive level is: ".$level."\n"; echo "Is it recursive ?
