Q:

PHP printing string

I am using var_dump for printing a variable, named $info. Now I need to print message_id as shown below, but the string is not getting print.
object(stdClass)[10]
  public 'date' => string 'Sun, 14 Oct 2012 19:45:26 +0100' (length=31)
  public 'Date' => string 'Sun, 14 Oct 2012 19:45:26 +0100' (length=31)
  public 'subject' => string 'deposit' (length=7)
  public 'Subject' => string 'deposit' (length=7)
  public 'message_id' => string '<CAKvS7sNb0Cb1AaAbCdEFGHerp5UyJuhfkcJj8P+8CZQj4VTGLA@mail.gmail.com>' (length=68)
  public 'toaddress' => string 'sbsa secretaccount <test@gmail.com>' (length=43)

I'm using this line,
echo $info->message_id;

Also if I try this,
$temp =  '<CAKvS7sNb0Cb1AaAbCdEFGHerp5UyJuhfkcJj8P+8CZQj4VTGLA@mail.gmail.com>';
echo "::$temp::";

Only :::: is getting printed, the $temp variable is ignored? Why?

A:

You have an object, not an array. Use:
echo $info->message_id;

php.net - Objects
In response to your second point - as the string is encapsulated in < and >, the browser will try and display this as HTML, if you view the source of the page, you will see that your $temp string is in there.
You could use htmlentities() in order to convert the characters to HTML entities:
echo htmlentites($temp);
