Unary operators take only one value, for example , which takes three values; this is usually referred to simply as "the ternary operator" (although it could perhaps more properly be called the conditional operator). The addition of parentheses to show the implicit order makes this clearer: Other Language books' operator precedence section usually include "(" and ")" - with exception of a Perl book that I have. However, PHP Manual is not listed "(" and ")" in precedence list.
A full list of PHP operators follows in the section Operator Precedence. It looks like "(" and ")" has higher precedence as it should be.
If you find it hard to remember operators precedence you can always use parenthesys - "(" and ")".
And even if you get to learn it remember that being a good programmer is not showing you can do code with fewer words.
Here's a complete list of PHP's arithmetic operators: "Pink"); $z = $x $y; // Union of $x and $y var_dump($z); var_dump($x == $y); // Outputs: boolean false var_dump($x === $y); // Outputs: boolean false var_dump($x !
This means you can't use the '
