Getting span contents with “Simple HTML DOM” - php

Question

I'm trying to scrape Twitter tweets from a user page using “Simple HTML DOM”.
I can get the tweets but not their timestamp.
The HTML seems to be like this:
<p class="ProfileTweet-text js-tweet-text u-dir" lang="en" dir="ltr" data-aria-label-part="0">Tweet content<a href="/hashtag/TweetContent?src=hash" data-query-source="hashtag_click" class="twitter-hashtag pretty-link js-nav" dir="ltr" ><s>#</s><b>TweetContent</b></a> <a href="http://t.co/JFredfvgYs" class="twitter-timeline-link u-hidden" data-pre-embedded="true" dir="ltr" >pic.twitter.com/JFredfvgYs</a></p>
The UNIX timestamp is in this:
<span class="js-short-timestamp "
data-aria-label-part="last"
data-time="1411584273"
data-long-form="true" >
Sep 24
</span>
So I'm doing:
<?php
include 'simple_html_dom.php';
$html = file_get_html('https://twitter.com/UserName');
$tweets = $html->find('div.ProfileTweet-contents');
foreach ($tweets as $tweet) {
$tweetText = $tweet->find('p.ProfileTweet-text', 0)->plaintext;
echo $tweetText;
}
?>
... which is fine for getting the tweet text but I don't know how to approach getting that Unix timestamp.
I thought maybe:
<?php
include 'simple_html_dom.php';
$html = file_get_html('https://twitter.com/UserName');
$tweets = $html->find('div.ProfileTweet-contents');
foreach ($tweets as $tweet) {
$tweetText = $tweet->find('p.ProfileTweet-text', 0)->plaintext;
$tweetDate = $tweet->find('span.js-short-timestamp ', 0);
echo $tweetText.' '.$tweetDate->data-time;
?>
... but that's all wrong. Any help?

Most likely because of that property that you're trying to access. Wrapped that hypenated property with this:
$tweetDate->{'data-time'};
Rough example:
$html = file_get_html('https://twitter.com/katyperry');
$tweet_block = $html->find('div.ProfileTweet');
foreach($tweet_block as $tweet) {
// get tweet text
$tweetText = $tweet->find('p.ProfileTweet-text text', 0)->innertext;
echo 'Tweet: ' . $tweetText . '<br/>';
// get tweet stamp
$tweetDate = $tweet->find('a.ProfileTweet-timestamp span.js-short-timestamp', 0);
echo 'Timestamp: ' .$tweetDate->{'data-time'} . '<br/>';
echo '<hr/>';
}
