Initializing array shared values at once

Maybe this isn't possible, I've never seen it myself, but thought I'd ask. If this is my array,

$myarr = arr开发者_开发百科ay(
   'red'   => 7, 
   'green' => 7,
   'blue'  => 18,
   'cyan'  => 14, 
   'pink'  => 18
   'brown' => 18
);

is there a way while initializing the array to set similar values at once? like

'red' && 'green' =>7, 
'blue' && 'pink' && 'brown' => 18,
'cyan' =>14

of course I'm not expecting this syntax to work but is there something that gets me the same idea?

PHP Manual does not provide description of any way to do that. BTW, you may initialize values in the following way:

$myarr['red'] = $myarr['green'] = 7;
$myarr['blue'] = $myarr['pink'] = $myarr['brown'] = 18;
$myarr['cyan'] = 14;

It isn't possible and, honestly, I fail to see a situation it could be useful if the repeated values are in the same array.

Would you like to provide an example, in order for me to get it?

A fun aside:

$bibi = array (
   'foo' == 'bar' => 2,
);
$bubu = array (
   'foo' && 'bar' => 2,
);

Both this syntaxes actually evaluate the expressions on the left. As in, in 2 is assigned to $bibi[0] and $bubu[1].
