Question

I want to add a language parameter. Suppose the user clicks on English, he will get tweets only in English. Right now I am using en by default, but I want support for multiple language

function twitter_class()
{
    $this->realNamePattern = '/\((.*?)\)/';

    $this->searchURL = 'http://search.twitter.com/search.atom?lang=en&q=';
}

$ch= curl_init($this->searchURL . urlencode($q));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);

I want to get the language input from the user.

Answer 1

You can make searchURL some parametrized string function:

$this->searchURL = function($language, $query) {
    $vars = array_map('urlencode', func_get_args() + array('', ''));        
    return vsprintf('http://search.twitter.com/search.atom?lang=%s&q=%s', $vars);
}

When you invoke it, do it like this:

$ch = curl_init($this->searchURL($lang, $q));

Hope this is helpful.

If you don’t have PHP 5.3, just write it as a standard class function:

class twitter_class
{
    ...

    function twitter_class()
    {
        $this->realNamePattern = '/\((.*?)\)/';
    }

    function searchURL($language, $query) {
        $vars = array_map('urlencode', array($language, $query));
        return vsprintf('http://search.twitter.com/search.atom?lang=%s&q=%s', $vars);
    }

    ...

        $ch = curl_init($this->searchURL($lang, $q));
    ...
}
