Question

I created a script that can get the unread email list as a feed from the Gmail.
Here is my code:

<?php
//function to get unread emails taking username and password as parameters
function check_email($username, $password)
{ 
    //url to connect to
    $url = "https://mail.google.com/mail/feed/atom"; 

    // sendRequest 
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_USERPWD, $username . ":" . $password);
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_ENCODING, "");
    $curlData = curl_exec($curl);
    curl_close($curl);
    //returning retrieved feed
    return $curlData;

}

//making page to behave like xml document to show feeds
header('Content-Type:text/xml; charset=UTF-8');
//calling function
$feed = check_email("username", "password");
echo $feed;
?>

The output getting like this:

<?xml version="1.0" encoding="UTF-8"?>
<feed version="0.3" xmlns="http://purl.org/atom/ns#">
<title>Gmail - Inbox for [e-mail]</title>
<tagline>New messages in your Gmail Inbox</tagline>
<fullcount>1282</fullcount>
<link rel="alternate" href="http://mail.google.com/mail" type="text/html" />

I want to read the:

<fullcount>1282</fullcount>

tag

When you pass the username and password to this function, it can show the email list.
I need to get only the message count.
Is there any way to catch or count the items?

Answer 1

this is the answer, i read the xml tag using php

$xmlobjc = new SimpleXMLElement($feed);

echo $xmlobjc->fullcount[0];

and replace the header with

header('Content-Type:text/html; charset=UTF-8');
