In my opinion:
- the operator table docs should be updated to contain all operators (
see comment
https://www.php.net/manual/en/language.operators.precedence.php#121509 )
- "new" should have the highest absolute priority, ie. new
Cl()->method(); should be always interpreted as (new Cl())->method();,
new (Cl()->method()); is very unusual and parenthesis can be always used
to enforce the intended precedence.

Hi devs,
currently new Cl() must be wrapped in parentheses if that object is
further used to call it's method like (new Cl())->method().
It there any reason why not to allow new Cl()->method() ?
Based on https://www.php.net/manual/en/language.operators.precedence.php
- the "new" operator has already the highest precedence, thus there
should be no conflict.
I think that's because removing the parentheses may confuse what was the original intention of author.
class CI {
public function method() { echo 'foo'; }
}
class bar {
public function __construct() {
echo 'bar';
}
}
function CI() {
return new class {
public function method() { return 'bar'; }
};
}
(new CI())->method(); // foo
new (CI()->method()); // bar
Both ways are valid code in PHP8 with no error/warning, till PHP7.4 there was a
Parse error: syntax error, unexpected '('
in the second object construction.
