Ignoring that this makes no sense since the expression in the
parantheses already yields a boolean value, I assume you are looking for
a PHP documentation of the ternary operator (which is not a Java
invention but has its roots in good old C). Here you are:
http://de.php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary
If you want to be sure that the result of your expression is of a
certain type (since you put a "boolean" at the beginning of the line and
PHP does not have strict typing), you can add a cast to the desired type:
$isNull = (bool) ($myObj==null) ? true : false;
Of course you are triple ensuring what can be accomplished by the PHP
engine internal function:
$isNull = is_null($myObj);
