php Array数组转换问题

Array(    [strwarenum] => Array        (            [0] => 1            [1] => 1        )    [strwareid] => Array        (            [0] => 80            [1] => 79        ))

Array(    [config_id] =>     [strwareid] => ,78,80    [strwarenum] => ,1,1    [config_name] =>     [config_desc] =>     [diycat_id] => )

foreach($b as $k => $v){    $a[$k][]='';    $v=array_reverse($a[$k]);}var_export($b);

Array(    [strwarenum] => Array        (            [80] => 1            [78] => 1        )    [strwareid] => Array        (            [0] => 80            [1] => 78        )    [config_id] =>     [config_name] =>     [config_desc] =>     [diycat_id] => )

$arr=你的数组;foreach($arr as &$v){     if(is_array($v)) $v=','.join(',',$v);}print_r($arr);
