Create an array from SimpleXMLElement response in php - php

Question

I am trying to import Google contacts in my code. I've successfully imported the contacts but my problem is that, I have to create an array of imported email addresses and I need to pass it to another page. But when I try to create an array, I get an array containing SimpleXMLElement Object.
Here is my code:
oauth.php:
<?php
$client_id='my-cient-id';
$client_secret='my-client-secret';
$redirect_uri='my-redirect-uri';
$max_results = 100;
$auth_code = $_GET["code"];
function curl_file_get_contents($url)
{
$curl = curl_init();
$userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';
curl_setopt($curl,CURLOPT_URL,$url);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($curl,CURLOPT_CONNECTTIMEOUT,5);
curl_setopt($curl, CURLOPT_USERAGENT, $userAgent);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($curl, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($curl, CURLOPT_TIMEOUT, 10);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
$contents = curl_exec($curl);
curl_close($curl);
return $contents;
}
$fields=array(
'code'=> urlencode($auth_code),
'client_id'=> urlencode($client_id),
'client_secret'=> urlencode($client_secret),
'redirect_uri'=> urlencode($redirect_uri),
'grant_type'=> urlencode('authorization_code')
);
$post = '';
foreach($fields as $key=>$value) { $post .= $key.'='.$value.'&'; }
$post = rtrim($post,'&');
$curl = curl_init();
curl_setopt($curl,CURLOPT_URL,'https://accounts.google.com/o/oauth2/token');
curl_setopt($curl,CURLOPT_POST,5);
curl_setopt($curl,CURLOPT_POSTFIELDS,$post);
curl_setopt($curl, CURLOPT_RETURNTRANSFER,TRUE);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER,FALSE);
$result = curl_exec($curl);
curl_close($curl);
$response = json_decode($result);
$accesstoken = $response->access_token;
$url = 'https://www.google.com/m8/feeds/contacts/default/full?max-results='.$max_results.'&oauth_token='.$accesstoken;
$xmlresponse = curl_file_get_contents($url);
if((strlen(stristr($xmlresponse,'Authorization required'))>0) && (strlen(stristr($xmlresponse,'Error '))>0)) //At times you get Authorization error from Google.
{
echo "<h2>OOPS !! Something went wrong. Please try reloading the page.</h2>";
exit();
}
echo "<h3>Email Addresses:</h3>";
$xml = new SimpleXMLElement($xmlresponse);
$xml->registerXPathNamespace('gd', 'http://schemas.google.com/g/2005');
$result = $xml->xpath('//gd:email');
foreach ($result as $title) {
$var=$title->attributes()->address;
echo $var . "<br>"; //here imported contacts is listing properly
$gc[]=array($var); // creates my contacts array
}
print_r($gc); //printing the created array
?>
My result is:
Array ( [0] => Array ( [0] => SimpleXMLElement Object ( [0] => email-address1 ) ) [1] => Array ( [0] => SimpleXMLElement Object ( [0] => email-address2 ) ) )
I need to get like this:
Array ( ([0] => email-address1 ) ( [1] => email-address2 ) )
Can anyone suggest me how to do this. I'm stuck in this for many days. Thanks in advance
Edit
XML Response:
Array ( [0] => SimpleXMLElement Object ( [#attributes] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => emailaddress1 [primary] => true ) ) [1] => SimpleXMLElement Object ( [#attributes] => Array ( [rel] => http://schemas.google.com/g/2005#other [address] => emailaddress2 [primary] => true ) ) )
I have to separate the emailaddress from the response to a php array.!
Edit 2
here is $xmlresponse:
email-id 2015-01-07T09:03:23.311Z profile-name email-id Contacts 2 1 100 http://www.google.com/m8/feeds/contacts/email-id/base/6cc9fe478fd427bb 2014-12-30T04:54:29.902Z
email-id is the mail id from which contacts are imported.

Answer 1

In the first line of the final foreach loop you could try:
$var=(string)$title->attributes()->address;
or:
$var=(string)$title->attributes()->address[0];
Which is a bit of code from http://php.net/manual/en/simplexml.examples-basic.php#116435
I think that the echo statement that lists the email addresses properly is implicitly calling the SimpleXMLElement::_toString(void) method (http://php.net/manual/en/simplexmlelement.tostring.php). So to get the same result when creating the array you can coerce it to a string by putting (string) in front of the variable name.
EDIT:
You might also try this where you add to the array:
$gc[] = $var;
instead of
$gc[] = array($var);
Since the second way creates a new array object and adds $var to it then the assignment operator adds that entire array to $gc. Which would explain why the SimpleXMLObject was itself in an array. The first way ('$gc[] = $var;') will add a new element to the array $gc. Or you could initialise $gc before the foreach loop with:
$gc = array();
And then inside the foreach loop use:
array_push($gc, $var);
You will need to do both of the suggested changes to get the result you want, so:
foreach ($results as $title) {
$var=(string)$title->attributes()->address;
$gc[] = $var;
