What is the PHP ? : operator called and what does it do?

I feed like a goof but I don’t entirely understand what’s happening in this code:

$var .= ($one || $two) ? function_one( $one, $another) : function_two( $two, $another);

Does that say if $one or $two then $var is equal to fuction_one(), else function_two()? What’s the purpose of using this syntax — speed?

Answer 1

If either $one is true, or $two is true, then the result of calling function_one is appended to $var. Otherwise, the result of calling function_two is appended to $var.

It’s basically shorthand for:

if ($one || $two) {
  $var .= function_one( $one, $another);
} else {
  $var .= function_two( $two, $another);
}
