Both sides of the "spaceship" are equal, so the answer is 0. PHP will convert '76 trombones' to 76 in this context, as the string starts with '76'. Try it! For php 8.0 and forward the answer is [x] -1, for previous versions the answer is [x] 0. PHP 8 changed the way non-strict comparison between numbers and non-numeric strings work.
