Description:
------------
On php7, $argi & $argn is changed from php5.
Is the intended change?
% echo 12 | ./php-7.0.3/sapi/cli/php -R 'echo $argi, PHP_EOL;'
0
% echo 12 | ./php-7.0.3/sapi/cli/php -R 'echo $argn, PHP_EOL;'
1

Or do I use any alternate variables?
On php5, I think that $argi & $argn is correct.
% echo 12 | ./php-5.6.18/sapi/cli/php -R 'echo $argi, PHP_EOL;'
1
% echo 12 | ./php-5.6.18/sapi/cli/php -R 'echo $argn, PHP_EOL;'
12



Expected result:
----------------
% echo 12 | ./php-7.0.3/sapi/cli/php -R 'echo $argi, PHP_EOL;'
1
% echo 12 | ./php-7.0.3/sapi/cli/php -R 'echo $argn, PHP_EOL;'
12
