PHP convert nested array to single array while concatenating keys?

Question

Here is an example array:

 $foo = array(
           \'employer\' => array(
                    \'name\' => \'Foobar Inc\',
                    \'phone\         


        

Answer 1

This will flatten a multidimensional associative array tacking a digit to the key if its a duplicate. If you don't mind having a digit index to differentiate duplicate keys instead of concatenated keys this could be a solution.

$result = array();
array_walk_recursive($your_array, function($v, $k) use (&$result){ $i = ""; for (; isset($result[$k."$i"]); $i++); $result[$k."$i"] = $v; });

I suspect it could be worked on further to do concatenated keys.

The above solution is basically for doing this kind of thing

        
            0                  
        
        
            10
        
    ";
                    // turn the xml into a multidimentional array
            $ob = simplexml_load_string($xml_str);
            $json = json_encode($ob);
            $my_array = json_decode($json, true);

            print_r($my_array);
                    // flatten it
            $result = array();
            array_walk_recursive($my_array, function($v, $k) use (&$result){ $i = ""; for (; isset($result[$k."$i"]); $i++); $result[$k."$i"] = $v; });

            print_r($result);
?>
