PHP - iterate through array and only show certain values -

i trying show selection of transactions using php , paypal's nvp transactionsearch method.

i transactions appear cannot tidy response , show specific values after - in case being following 4 values per transaction:

l_timestamp,  l_type,  l_transactionid 

my current code is:

$request = http_build_query(array(     "method"    => $action,     "version"   => $config['version'],     "user"      => $config['username'],     "pwd"       => $config['password'],     "signature" => $config['signature'],     "startdate" => $start,     "email" => $email, ));  $ch = curl_init(); curl_setopt($ch, curlopt_url, $url); curl_setopt($ch, curlopt_verbose, 1); curl_setopt($ch, curlopt_ssl_verifypeer, false); curl_setopt($ch, curlopt_ssl_verifyhost, false); curl_setopt($ch, curlopt_returntransfer, 1); curl_setopt($ch, curlopt_post, 1);     curl_setopt($ch, curlopt_postfields, $request);  $result = curl_exec($ch);  if (!$result) {     echo 'no results'; }  parse_str($result, $result);  foreach($result $key => $value){     echo $key.' => '.$value."<br />"; } 

which outputs in 1 below :

l_timestamp0 => 2014-01-15t11:29:21z l_timestamp1 => 2014-01-15t11:09:05z l_timezone0 => gmt l_timezone1 => gmt l_type0 => refund l_type1 => payment l_transactionid0 => 7my22222222222914 l_transactionid1 => 2045555555555594d  , on... 

how can instead output this: (so goes through each transaction next rather each 'value' , onto next, plus not show timezone key)

l_timestamp0 => 2014-01-15t11:29:21z l_type0 => refund l_transactionid0 => 7my22222222222914  l_timestamp1 => 2014-01-15t11:09:05z l_type1 => payment l_transactionid1 => 2045555555555594d 

i think array of arrays better option:

foreach($result $k => $v) {     preg_match('~([a-z_]+)(\d+)$~', $k, $m);     $nested[$m[2]][$m[1]] = $v; } 

which creates nested array this:

array (     [0] => array         (             [l_timestamp] => 2014-01-15t11:29:21z             [l_timezone] => gmt             [l_type] => refund             [l_transactionid] => 7my22222222222914         )      [1] => array         (             [l_timestamp] => 2014-01-15t11:09:05z             [l_timezone] => gmt             [l_type] => payment             [l_transactionid] => 2045555555555594d         )  ) 

it should easy generate desired output this.
