Server Side Scripting / Coding: preg_match and xml elements from a Twitter feed
Bottom of Page1 to 3 of 3
-
I need some php to extract the latest addition to my Twitter feed...
Eg, the 'description' element from within 'item' from http://twitter.com/statuses/user_timeline.rss?count=1
The below gives me the first description, where $result is the contents of the xml feed:$description=preg_match("/<description>(.*?)<\/description>/", $result, $matchtitle);
$ticker="$matchtitle[1]";
But I need the second instance of description, eg 'James Greig: Wondering how many people use twitter!?!?!?!'
Can I get this using reg_match_all? I want to keep this simple and not use an external xml parsing script, if poss :) -
Think I got it:
$description=preg_match_all("/<description>(.*?)<\/description>/", $result, $matchtitle);
print '<h3>'.substr($matchtitle[0][1],13,-14).'</h3>';
Is there a better way to do this though?
My entire script looks like this now: (Output here)
<?php
function getLatestTwitter($username,$password) {
$host = "http://twitter.com/statuses/user_timeline.rss?count=1";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_POST, 1);
$result = curl_exec($ch);
curl_close($ch);
$description=preg_match_all("/<description>(.*?)<\/description>/", $result, $matchtitle);
print '<h3>'.substr($matchtitle[0][1],13,-14).'</h3>';
}
getLatestTwitter("3stripe","passwordgoeshere");
?> -
I just use lastRSS, I really suck at regular expressions.
