tweetsigniter Documentation

Let's see step by step explanation of our tweetsigniter class, a twitter codeigniter library. Initially, we have declared all our necessary global variables, like username, password, path, template, timezone etc.

# username field
    public $username;
    # password field
    public $password;
    # maximum no. of values
    public $maxItems;
    # path value
    public $path;
    # timezone value
    public $timezone;
    public $configs = array();
    # template file name
    public $template;

Next comes the constructor method. it defines our template variable. we will replace the template values.

public function  __construct()
    {
        $this->template = "
{text}
";
    }

we set the necessary values with this method like username, password, maxItem shows the maximum no. of items to be displayed, and timezone will be your timezone.

public function setInfo($username, $password, $maxItems = '5', $timezone = '+6')
    {
        $this->username = $username;
        $this->password = $password;
        $this->timezone = $timezone;
        $this->maxItems = $maxItems;
        $this->config();
    }

We set necessary configuraion Information with these function.

public function config()
    {
        $this->configs['template'] = $this->template;
        $this->configs['maxitems'] = $this->maxItems;
    }

The following function shows all your tweets. you can apply css style within the html elements. the cut and resume functions process tweeter responses.

public function easyfeeder()
    {
        $content=$this->twitterXml('http://twitter.com/statuses/user_timeline.xml');
        $items=explode("",$content);
        array_shift($items);

        $retstr="
Latest News
";          foreach($items as $cnt=>$item)         {             if($this->configs['maxitems']>0 and $cnt+1>$this->configs['maxitems']) break;              $created_at=$this->cut("","",$item);             $text=$this->cut("","",$item);             $itemid=$this->cut("","",$item);             $screenname=$this->cut("","",$item);              $created_day = substr($created_at, 0, 3);             $created_monthday = substr($created_at, 4, 6);             $created_timehour = substr($created_at, 11, 2);             $created_timehour = $created_timehour + $this->timezone;             $created_timeminutes = substr($created_at, 14, 2);             $created_year = substr($created_at, 26, 4);             if ($created_timehour == 12) {                 $ampm = "pm";             } else if (($created_timehour > 12) AND ($created_timehour < 24)) {
                $ampm = "pm";
                $created_timehour = $created_timehour - 12;
            } else if ($created_timehour == 24) {
                $ampm = "am";
                $created_timehour = 12;
            } else {
                $ampm = "am";
            }

            $created_at = $created_day . ", " . $created_monthday . ", " . $created_year . " - " . $created_timehour . ":" . $created_timeminutes . $ampm;
            $itemlink = "http://twitter.com/" . $screenname . "/statuses/" . $itemid;

            $tpl=$this->configs['template'];              $tpl=str_replace("{created_at}",$created_at,$tpl);             $tpl=str_replace("{text}",$text,$tpl);             $tpl=str_replace("{itemlink}",$itemlink,$tpl);              $retstr.=$tpl;         }         $retstr.="
";
        return $retstr;
    }

Following is the cut and resume methods that we used in the above method.

public function cut($start,$end,$word)
    {
        $word=substr($word,strpos($word,$start)+strlen($start));
        $word=substr($word,0,strpos($word,$end));
        return $word;
    }

    public function resume($text,$limit=7)
    {
        $words=@explode(" ",$text);
        $words=@array_splice($words,0,$limit);
        $retstr=@implode(" ",$words);
        return $retstr."... ";
    }

The following method will show all you tweeter followers.

public function twitterFollowers()
    {
        $this->template = "

";
        $content=$this->twitterXml('http://twitter.com/statuses/followers.xml');

        $items=explode("",$content);
        array_shift($items);

        $retstr="
Latest News
";          foreach($items as $cnt=>$item)         {             if($this->configs['maxitems']>0 and $cnt+1>$this->configs['maxitems']) break;              $created_at=$this->cut("","",$item);             $text=$this->cut("","",$item);             $itemid=$this->cut("","",$item);             $screenname=$this->cut("","",$item);              $itemlink = "http://twitter.com/" . $screenname;              $tpl=$this->template;              $tpl=str_replace("{text}",$text,$tpl);             $tpl=str_replace("{itemlink}",$itemlink,$tpl);              $retstr.=$tpl;         }         $retstr.="
";
        return $retstr;
    }

This method will show all your tweeter friends.

public function twitterFriends()
    {
        $this->template = "

";
        $content=$this->twitterXml('http://twitter.com/statuses/friends.xml');

        $items=explode("",$content);
        array_shift($items);

        $retstr="
Latest News
";          foreach($items as $cnt=>$item)         {             if($this->configs['maxitems']>0 and $cnt+1>$this->configs['maxitems']) break;              $created_at=$this->cut("","",$item);             $text=$this->cut("","",$item);             $itemid=$this->cut("","",$item);             $screenname=$this->cut("","",$item);              $itemlink = "http://twitter.com/" . $screenname;              $tpl=$this->template;              $tpl=str_replace("{text}",$text,$tpl);             $tpl=str_replace("{itemlink}",$itemlink,$tpl);              $retstr.=$tpl;         }         $retstr.="
";
        return $retstr;
    }

let's see how we have connected with tweeter. we used curl to connect with tweeter. the following method done the trick for us.

function twitterXml($url)
    {
        $curl_handle = curl_init();
        curl_setopt($curl_handle, CURLOPT_URL, "$url");
        curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2);
        curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($curl_handle, CURLOPT_USERPWD, "$this->username:$this->password");
        $buffer = curl_exec($curl_handle);
        curl_close($curl_handle);

        return $buffer;
    }
