Assigning variables on one line

Orc · 03-19-2008, 03:12 PM

How would I do a multiple variable assigning?

example

PHP Code:


			

$foo = 'bar' && $bar = 'foo';

Update: Well my true use would be to assign $foo and $bar to the same value without more lines. Only on one line and clustered together using a comma or whatever.

I'm not entirely sure myself...
I can't really see why you wouldnt just want to..

PHP Code:


			
$foo =  'bar'; $bar = 'foo';

White space doesn't matter, you just need to be sure you end your statement.

I understand that method, :] But I just want to do it in a cluster.

I figured out a way for it to work:

PHP Code:


			
<?php
$foo = $bar = 'foo';

?>

But this isnt two separate values, this is just clustering $foo into $bar which assigns to $foo but umm, I still want to do it clustered multipled variables, with different values.

Yeah, I knew you could do that, I just didn't think you wanted to assign the same value to more than one variable.

;p

Ah well.. I will just do the original method:

PHP Code:


			


$foo = 'foo';

$bar = 'bar';

How about this?

php Code:

list($foo, $bar) = array('foo', 'bar');

well that was my first thought.

yeah, that would work. you could also just load an array up:

PHP Code:


			


$myVars = array(

              'foo' => 'bar',

              'bar' => 'foo'

          );

foreach($myVars as $key => $val) {

   ${$key} = $val;

}

if you just want to do a crap load of vars

If you were going to use an associative array, then extract() would be better than the foreach loop. Though, I'm still struggling to see the purpose here. Why not just assign the values 'normally'... keep it simple.

Extract

PHP Code:


			
$vars = array
(
    'foo' => 'bar',
    'baz' => 'foo'
);
extract($vars);
var_dump($foo, $baz);

Less lines of code? :P

Mmmm, can I know in which use case you need to do that ??

The speed boost gained by less line of code is insignificant as best, readability of your code also goes down loads - it looks nice and obfuscated but keep it simple.
