It's worth nothing that, if T_IFSETOR was recognized by the scanner as "?:", then Sascha/GCC "?:" operator is also implemented by this patch, by changing the parser rule from this:
T_IFSETOR '(' variable ',' expr ')'
to this:
T_IFSETOR variable ':' expr

[RFC] ifsetor operator
Hello List,
i also agrre that an internal function is much better. And here is it as such an internal function (that does not result in an expensive function call).
Synopsis: "ifsetor" "(" value "," default ")"
Returns the value if it exists or a given default value.
Syntax: "ifsetor" "(" variable [ "," expression ] ")"
Semantic: - The value in question must be a variable. - The default value can be any expression. - The default value can be omitted in which case NULL will be used.

Hello Jason,
here is your operator patch: http://marcus-boerger.de/php/ext/ze2/ze2-ifsetor-20040416.diff.txt
currently it uses the following syntax:
$var $: $defaul
which would equal
isset($var) ? $var : $default
Notice that at the moment the operator is '$:' and not '?:'. This is because i haven't looked on how to solve the conflicts i get when i use '?:'. If there is more interest in that operator i could invest more work in trying to fix that problem.
best regards marcus
According to your options and the possibility to implement this as a
function. That would only work as a parser internal function like empty
or set. Doing so would be very easy i guess. Though it would require a
new keyword say 'ifsetor' (which reflects its purpose more as 'setor').
best regards marcus
