how to get all keys of this multidimensional array

Question

I have similar problem, which is here: solved Problem

But I would like to get such an array in return as final result for this demo array in 1.

thanks a lot!

return array I would like to get:

    [0] => "0.name "
    [1] => "0.id "
    [2] => "0.phone "
    [3] => "0.Base.city "
    [4] => "0.EBase.city "
    [5] => "0.Qty "
    [6] => "1.name "
    [7] => "1.id "
    [8] => "1.phone "
    [9] => "1.Base.city "
    [10]=> "1.EBase.city "
    [11]=> "1.Qty "

I have tried this: But does not work:

        function array_flat(array $myarr)            
        {            
            $myline = "";            
            foreach ($myarr as $key => $value)            
                {            
                if ( $myline == "" ){$myline=sprintf("%s",$myarr[$key]);}            
                else {$myline=sprintf("%s%s",$myline,$myarr[$key]);}            
                }            
            return array($myline);            
        }            

        function array_keys_multi(array $array)            
        {            
            $keys = array();            

            foreach ($array as $key => $value) {            
            $keys[] = $key;            

            if (is_array($value)) {            
                $keys = array_merge($keys, array_keys_multi($value));            
            }            
                else {            
                    $keys = array_flat($keys);            
                }            

            }            

            return $keys;            
        }

Moreover I have found this:Maybe it could help to solve my request: get all path of an array

Do you mean that you want all keys from the key 1 of your array? — Aefits, Sep 13 '17 at 12:05
What is your expected result? Do you want the recursive keys as a string? Do you want a new array containing all keys? If the latter, how do you want to represent recursively found keys? As a new recursive array or something like dot-separation (e.g. 0.EBase.city) ? Please update question with more info... — rkeet, Sep 13 '17 at 12:21
@Nukeface thanks for your help, please see my edited question — Walter Schrabmair, Sep 13 '17 at 12:39

Yes this link did what I wanted: Solution

             function getKeyPaths(array $tree, $glue = '_')                    
             {                                                                 
                 $paths = array();                                             
                 foreach ($tree as $key => &$mixed) {                          
                     if (is_array($mixed)) {                                   
                         $results = getKeyPaths($mixed, $glue);                
                         foreach ($results as $k => &$v) {                     
                             $paths[$key . $glue . $k] = $v;                   
                         }                                                     
                         unset($results);                                      
                     } else {                                                  
                         $paths[$key] = $mixed;                                
                     }                                                         
                 }                                                             

                 return $paths;                                                
             }

to call it by:

     print_r(getKeyPaths($jsonquotesum));

Hi @Walter, though the link may have helped you, posting the solution (the code) that made it work for you in here would help others in the future. Especially since the link contains multiple code blocks ;) — rkeet, Sep 13 '17 at 14:24
@Nukeface thanks for trying to help, but I was faster (in searching the web :) ) — Walter Schrabmair, Sep 13 '17 at 16:17

Use array_key(). You will get all the keys. doc here:

no that is not correct, I think. It must be recursively through the whole tree. But the output should be like me request. – Walter Schrabmair Sep 13 '17 at 12:17
