PHP数组调试

Posted 2021-02-24

a more useful way of printing php arrays in a nice readable format and able to decode serialized and json_encoded strings.

function debug_r($array=null,$dump=false,$string_type='serialize')
{	
echo '<pre>'."
";		
if(is_array($array))
{
	if(count($array) > 0)
	{	
		if($dump)
		{
			var_dump($array);
		}else{
			print_r($array);
		}
	}else{
		echo "Array empty"."
";			
	}		
}else if(is_string($array))
{		
	switch($string_type)
	{
		default:
		case 'serialize':
			$array = unserialize($array);
		break;				
		case 'json':
			$array = json_decode($array);
		break;
	}		
	if(count($array) > 0)
	{
		if($dump)
		{
			var_dump($array);
		}else{
			print_r($array);
		}
	}else{
		echo "Array empty"."
";			
	}		
}else{		
	echo 'Invalid format'."
";		
}		
echo '</pre>'."
";		
}//end debug_r
