Bug description: if structure inherit else
Description:
------------
I'm requesting a way for the 'if' control struction to be able to inherit
'else' control structures, in a similar matter as below. This will help
prevent duplicated code, and help keep it clean and uncluttered.
I've included an 'expected_equivalent', which is actually less code than
in the 'routine' function. However, if a developer wishes to include a
greater diveristy, it can become a real advantage to use just one 'else'.
Additionally, it I think it would be benefitional for 'if' control
structure to make it more 'complete'.
I also understand there are already numerous ways to do this, which have
the same result and possibly even less code. Nonetheless, I believe this
way could be a better, easier way for certain situations.
Reproduce code:
---------------
<?php
function routine ($foo, $bar)
{
if ($foo === 0) echo "foo is 0\n";
elseif ($foo === 1)
if ($bar === 0) echo "bar is 0\n";
elseif ($bar === 1) echo "bar is 1\n";
else echo "foo: ".$foo.", bar: ".$bar."\n";
# else would apply to both elseif
}
function expected_equivalent ($foo, $bar)
{
if ($foo === 0) echo "foo is 0\n";
elseif ($foo === 1 && $bar === 0) echo "bar is 0\n";
elseif ($foo === 1 && $bar === 1) echo "bar is 1\n";
else echo "foo: ".$foo.", bar: ".$bar."\n";
}
routine (0, 1);
routine (1, 0);
routine (1, 1);
routine (2, 1);
routine (1, 2);
routine (2, 2);
?>
Expected result:
----------------
foo is 0
bar is 0
bar is 1
foo: 2, bar: 1
foo: 1, bar: 2
foo: 2, bar: 2
Actual result:
--------------
foo is 0
bar is 0
bar is 1
foo: 1, bar: 2
