Although the manual warned you not to unset element, but sometimes thus is very useful and work as
charm:
$arrChnOut=array(0=>array('ID' => '13',
'ChannelName' => 'Computers'
),
1=>array('ID' => '17',
'ChannelName' => 'Computers'
),
2=>array('ID' => '18',
'ChannelName' => 'Computers'
),
);
array_walk($arrChnOut, create_function('&$v, $k, $arr_rtn', 'if
($k{0}!="_"){$arr_rtn["_".$v[\'ID\']]=$v;unset($arr_rtn[$k]);}'),
&$arrChnOut);
var_export($arrChnOut);
