I think i’m having similar issues with the Twitter feed I’m using on my site. The feed has stopped pulling in individual posts. I’m avoiding the timeline because I need a solution that provides SEO benefit to our site.
Here’s my code:
<?php
/* Class to embed twitter comments for a user into a website page (PHP) */
class myTwit{
var $user = false; // User to show public posts
var $cacheFile = ‘twitcache.txt’; // File to save local cache of Twitter update
var $cachExpire = 600; // Seconds that cache is classed as "old"
var $myTwitHeader = false;
var $postLimit = 20; // 20 = max
var $debug = false;
var $targetBlank = true;
var $postClass = false;
function printError($message){ echo htmlspecialchars($message); exit;}
function debugMsg($message){if ($this->debug == true) echo htmlspecialchars($message).'<br />';}
function formatPlural($val, $qty){
if ($val > 1) return $val.' '.$qty.'s';
else return $val.' '.$qty;
}
function intoRelativeTime($seconds){
if (($seconds / 60 / 60 / 24) > 1) return $this->formatPlural(round($seconds / 60 / 60 / 24), 'day').' ago';
elseif (($seconds / 60 / 60) > 1) return 'about '.$this->formatPlural(round($seconds / 60 / 60), 'hour').' ago';
else if (($seconds / 60 ) > 1) return 'about '.$this->formatPlural(round($seconds / 60), 'minute').' ago';
else return 'about '.round($seconds).' seconds ago';
}
function linkURLs($text){
$in=array( '`((?:https?|ftp)://\S+[[:alnum:]]/?)`si', '`((?<!//)(www\.\S+[[:alnum:]]/?))`si' );
$out=array( '<a href="$1"'.$this->targetAppend.'>$1</a> ', '<a href="http://$1" target="_blank">$1</a>' );
$text = preg_replace($in,$out,$text);
$text = preg_replace('/@([a-zA-Z0-9-_]+)/','@<a href="http://twitter.com/$1"'.$this->targetAppend.'>$1</a>',$text);
return $text;
}
