On my php page, I am getting the follow output:
Array ( [contact/email] => users_name@email_address.com )
This is produced via the following line in the php code:
print_r($openid->getAttributes()开发者_如何学C);
How do I extract the text users_name@email_address.com
from that array and stick it into a variable $strEmail;
?
So when I echo the variable:
echo $strEmail;
It should output the following on screen:
users_name@email_address.com
Assign the array to a variable and then you can easily access it:
$attributes = $openid->getAttributes();
$strEmail = $attributes['contact/email'];
echo $strEmail; // => users_name@email_address.com
In your specific case, you can do:
$strEmail = reset($openid->getAttributes());
However it's better to suggest as this will work for other cases,too:
$attributes = $openid->getAttributes();
$strEmail = $attributes['contact/email'];
For more details see the PHP Manual about arrays how to access them.
