Can someone please explain, why the results are different in below two cases?
<?php
echo ((7)??0 / (15)??1);
echo "<br><br>";
echo (((7)??0) / ((15)??1));
?>

See Operator Precedence in the PHP manual.
??
has higher precendance than /
so in the first example since 7
is a true value it wins.
In the second example, the parentheses force precedence.
