How to generate new address for blockchain wallet

Question

I am trying to generate new address for each wallet using blockchain API using the following code:

<?php

$guid = "7c74bb77-4e25-4eea-a9d3-df1cf6a9d218";

$main_password = "******";

$label = "firsttym";

$json_url = "http://localhost:3000/merchant/$guid/new_address?

password = $main_password & label = $label";

$json_data = file_get_contents($json_url);

$json_feed = json_decode($json_data ,true);

$message = $json_feed->message;

$txid = $json_feed->tx_hash;

?>

I get the following error:

Warning: file_get_contents(localhost:3000/merchant/7c74bb77-4e25-4eea??-a9d3-df1cf6a9d218/…??) [function.file-get-contents]: failed to open stream:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

You can use the following to generate wallet addresses. 
Start the blockchain before making the request using this code:

blockchain-wallet-service start --port 3000

then use the following code:

$url = "http://localhost:3000/merchant/$guid/new_address?password=$password&label=$label";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

   $data = json_decode(curl_exec($ch), TRUE);

   return $data;
