Hi php internals,
After some long and deep research i finally decided to write my first RFC
about a feature i'd be interested to be improved in the php core: *Nested
enclosing returns*
The main purpose, as the title say, is to have the possibility to nest
multiple return like we can do currently with break/continue.
I thinks it'll being better with a scheme:
function foo($foo = true)
{
if(!$foo)
{
return false, 3;// Please note the second return argument is the
return nesting level
}
else
{
return true;// Default nested return argument is always equal to
1 (if not specified, current)
}
}
function bar($foo = true)
{
foo($foo);
// Some stuff that will never be executed if $foo == false and
nested return argument = 2
echo 'Hi jon !';
}
function baz($foo = true)
{
echo 'Hi bertie !';
foo($foo);
// Some stuff that will never be executed if $foo == false and
nested return argument = 3
echo 'Hi freddy !';
}
baz(true); // Display:
// Hi bertie !
// Hi jon !
// Hi freddy !
baz(false); // Display:
// Hi bertie !
Benefits:
-Wont break compatibility
-May improve code interpretation speed due to part of code skipped by the
nested return.
-Allow "dynamic" return expressions.
Inconveniences:
-May complicate debug/backtrace
