$data['pole']=array( 'address'=>'earth', 'phone number'=>'39028502753' );

echo '<pre>';
var_dump( getValuesByArray($data) );
echo '</pre>';

function getValuesByArray($targetArray){
    if( !is_array($targetArray) ){
        return array($targetArray);
    }
    $tmp=array();
    foreach($targetArray as $key => $value){
        $tmp=array_merge($tmp, getValuesByArray($value) );
    }
