why not try an implode()?
[this is assuming that you're trying concat with an array of course, and my assumption is based on your "foreach" statement]
it’s a native function, and may work to your benefit

example:
$orange = array(“orange”, “you”, “glad”, “i”, “didn’t”, “say”, “banana”);
$orange_str = implode(” “, $orange);
echo $orange_str; // “orange you glad i didn’t say banana”

doesn’t hurt to try. also, if you don’t like the word implode, you could simply use join() [i like this better because it's like python =)]

What is more likely the case, is in that first way you are actually creating a new string when you concat on $orange_str. While $orange_str .= actually appends to the existing string. This depends on the language. (i.e. Java strings are immutable so when you do += on a java string it actually has to make a brand new string)
