Simple PHP object dump for those large objects with huge blobs of text or deep nested structures

objectDump.php

<?php
/**
 * Simple object dump for those large objects with huge blobs of text or deep nested structures
 */
function objectDump($object, $size = 70, $max = 5, $level = 0)
{
	if($level > $max) return 'array(...MAX DEPTH REACHED...)';

	$tab = str_repeat("\t", $level);

	$safe = function($string) use(&$size) {
		$string = htmlspecialchars($string, ENT_QUOTES, 'utf-8');

		$string = preg_replace("~\n\s*~", ' ', str_replace("\r", '', $string));
		
		if(strlen($string) > $size) {
			return substr($string, 0, $size) . '...';
		}

		return $string;
	};

	$temp = array_flip(array_keys( (array) $object));

	foreach((array) $object as $key => $value) {
		
		if( ! is_scalar($value) AND $value) {
			$temp[$key] = objectDump($value, $size, $max, $level + 1);
			continue;
		}

		$temp[$key] = ($value === NULL ? 'null' : $safe($value));
	}

	if($level === 0) {
		print "<pre>\n" . print_r($temp, true) . "</pre>\n";
		return;
	}

	return $temp;
}

I get **Warning: htmlspecialchars() expects parameter 1 to be string, array given in /home/x/y/app/code/XXX/Shipping/Helper/Quote.php on line 232

And $tab is not used in your function btw.
