PHP Array Conversion

SOURCE array:

$attributes = array(    'Users' => array(        'Name' => 'Name',    ),    'Address' => 'Address',    'Tags' => array(        0 => array(            'Key' => 'Key',            'Value' => 'Value',        ),        1 => array(            'Key' => 'Key',        ),        2 => array(        )    ),);

You want to convert to the following array:

$result = array(    'Users_Name' => 'Name',    'Address' => 'Address',    'Tags_0_Key' => 'Key',    'Tags_0_Value' => 'Value',    'Tags_1_Key' => 'Key',    // 'Tags_2' => '',);

Recursive way to try a half-day, still no solution, how to convert it?

It would be nice if the empty array was to be converted.

  
    $val ) {        $key = array_merge( $prefix, array($key) );        if( is_array($val) ) $res = array_merge( $res, transfer( $val, $key, $glue ) );        else $res[ implode($glue, $key) ] = $val;    }    return $res;}$attributes = array(    'Users' => array(        'Name' => 'Name',    ),    'Address' => 'Address',    'Tags' => array(        0 => array(            'Key' => 'Key',            'Value' => 'Value',        ),        1 => array(            'Key' => 'Key',        ),        2 => array(        )    ),);var_dump( transfer( $attributes ) );

function t($parent_key, $parent_array, &$data) {    foreach ($parent_array as $k => $v) {        if (is_array($v)) {            t("${parent_key}_${k}", $v, $data);        } else {            $data[trim("${parent_key}_${k}", '_')] = $v;        }    }}$data = array();$attributes = array(    'Users' => array(        'Name' => 'Name',    ),    'Address' => 'Address',    'Tags' => array(        0 => array(            'Key' => 'Key',            'Value' => 'Value',        ),        1 => array(            'Key' => 'Key',        ),        2 => array(        )    ),);t('', $attributes, $data);print_r($data);

function deal($array, $prekey){    $res = array();    foreach ($array as $key => $val) {        if(is_array($val)){            $tmp = deal($val, $prekey.$key."_");            $res = array_merge($tmp, $res);        }else{            $res[$prekey.$key] = $val;        }    }    return $res;}print_r(deal($attributes, ''));
