Other Language books' operator precedence section usually include "(" and
")" - with exception of a Perl book that I have. (In PHP "{" and "}"
should also be considered also). However, PHP Manual is not listed "(" and ")"
in precedence list. It looks like "(" and ")" has higher precedence as it should
be.
Note: If you write following code, you would need "()" to get expected value.
<?php
$bar = true;
$str = "TEST". ($bar ? 'true' : 'false') ."TEST";
?>
Without "(" and ")" you will get only "true" in $str.
(PHP4.0.4pl1/Apache DSO/Linux, PHP4.0.5RC1/Apache DSO/W2K Server)
It's due to precedence, probably.
