Is this behaviour correct in PHP?
<?php echo '-' . 1 + 1 . ' crazy cats'; ?>
// Outputs:
0 crazy cats
I understand that minus is being concatenated to the first '1' and '-1' casted to integer, and not '2' to string.
Please explain why.
What is the best way to solve it? This one?
<?php echo '-' . (string)1 + 1 . ' crazy cats'; ?>
