Looking for workaround: print_r and var_export cannot run with ob_start's callback function

the functions print_r() and var_export() cannot be run within my ob_start's callback function because those functions use ob_start() internally.  Does anyone know of a workaround so I can simply spit out an array within my callback?
<?php
function mycallback ($buffer){
	$array=(1,2,3,4,5);
	
	//neither of these work
	$result=print_r($array,true);
	$result=var_export($array,true);
 
	$buffer.="<div class=\"debug\">".$result."</div>";
 
	return $buffer;
}
 
  ob_start("mycallback");//buffer on
    include("helloworld.html");
  ob_end_flush();
 
?>
