@Austin this can be done by changing @$i++= to @++$i<= so only one character must be added.

You can save 3 bytes removing unnecessary $n= in loop condition.

@BenoitEsnard You have to do $argv[1]*1 or $argv[1]+0, otherwise it will print 1 if you give it 0 when it is supposed to print nothing. At least, that's what happens in PHP 5.5.

I have a shorter one for you, but only for PHP 4: for($a=1;@$i++<$n=$N;$a.=" ".($i+print"$a\n"));, pass the URL parameter N=x. This works only on PHP<4.2 because of the directive register_globals (php.net/manual/en/ini.core.php#ini.register-globals) which automatically registers the variables in $_POST, $_GET and so on to the current code automatically. $_GET['Z'] will be registed as the variable $Z. This value defaults to on on those old versions. To work for PHP<5.3, you have to create a php.ini file with register_globals=on

@IsmaelMiguel: I've edited the answer with your idea. Using $argv[1] is better for the no-error version. Too bad we can't use $argc directly.

for($a=1;$i++<$n=$_GET[n];$a.=" ".($i+print"$a\n")); --> try this (full code, using url parameter n with the number)

| Mar 13, 2015 at 20:10 | comment | added | Austin | Sure, go for it. | |
| Mar 13, 2015 at 10:24 | comment | added | Benoit Esnard | Indeed. Are you OK if I edit my answer to add your solution? | |
| Mar 13, 2015 at 10:19 | comment | added | Austin |
Ah ok, then I suppose you would do function f($n){for($a=1;@$i++<$n;$a.=" ".($i+print"$a\n"));}, which is 60 bytes.

@Austin: I've read in a comment that the code must be either a full program reading from input, or a function. Very nice trick, it can be improved by a bit / byte: for($a=1;@$i++<$n;$a.=" ".($i+print"$a\n")); (44 bytes)

45 bytes: for($a=1;@$i<$n;$a.=" ".(@++$i+print"$a\n"));
