What to Expect When You're Expecting: PHP 7, Part 1 (Engine Yard)
The Engine Yard blog has an
introduction to the changes coming in the PHP 7 release.
"My personal favorite addition to PHP 7 is the addition of the
Combined Comparison Operator, <=>,otherwise known as the
spaceship operator. [...] It effectively works like strcmp(), or
version_compare(), returning -1 if the left operand is smaller than the
right, 0 if they are equal, and 1 if the left is greater than the
right. The major difference being that it can be used on any two operands,
not just strings, but also integers, floats, arrays, etc."
