Twitter PHP Script

/ Published in: PHP

A Twitter pull-in that I coded using PHP. Uses the JSON user_timeline Twitter API call. It displays the tweet with links to any urls, users, or hashtags, the time ago, and if it was in reply to anyone.

<?php
// the number of tweets we want to display
$tweetsToDisplay = 10;
$username = "username"; // make sure you change this to your username

$twitterrequest = 'http://api.twitter.com/1/statuses/user_timeline.json?screen_name=' . $username . '&count=' . $tweetsToDisplay;
$twitterci = curl_init($twitterrequest);
curl_setopt($twitterci,CURLOPT_RETURNTRANSFER, TRUE);
$twitterinput = curl_exec($twitterci);
curl_close($twitterci);

// parameter 'true' is necessary for output as PHP array
$tweets = json_decode($twitterinput,true);

echo "<h3><a href=\"http://twitter.com/$username\">Twitter Updates</a></h3>";

if(empty($tweets)){
	echo "Twitter doesn't seem to be working at the moment.";
}else if(!empty($tweets['error'])){
	echo "There was an issue with Twitter.";
}else{
	// Twitter uses the GMT timezone
	date_default_timezone_set('GMT');
	// This is Twitter's response date format
	$curDate = date('D M d H:i:s O Y');
