Twitter Search using the Twitter API v1.1 & PHP

I’ll introduce how to run a Twitter search, customize a query and an advanced technique, search & “auto follow”, using the Twitter API and PHP. Example codes in this post work with the version 1.1 of Twitter API. As usual, I’ll use the twitteroauth library by Abraham Williams to make an implementation easy: https://github.com/abraham/twitteroauth.

How to Run a Twitter Search

Code

<?php
require_once 'lib/twitteroauth.php';

define('CONSUMER_KEY', 'your_consumer_key');
define('CONSUMER_SECRET', 'your_consumer_secret');
define('ACCESS_TOKEN', 'your_access_token');
define('ACCESS_TOKEN_SECRET', 'your_access_token_secret');

function search(array $query)
{
  $toa = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);
  return $toa->get('search/tweets', $query);
}

$query = array(
  "q" => "happy birthday",
);
 
$results = search($query);
 
foreach ($results->statuses as $result) {
  echo $result->user->screen_name . ": " . $result->text . "\n";
}

define('ACCESS_TOKEN_SECRET', 'your_access_token_secret');

function find_users(array $users)
{
    $founds = array();

    $toa = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, ACCESS_TOKEN, ACCESS_TOKEN_SECRET);

    // Up to 100 users per request.
    $userAry = array_slice($users, 0, 100);

    // Init with "not found" for all users.
    foreach ($userAry as $user) {
        $founds[$user] = false;
    }

    // Find existing users by "screen_name".
    $userObjs= $toa->post('users/lookup', array('screen_name' => implode(',', $userAry)));

    // Set "found" for existing users.
    foreach ($userObjs as $userObj) {
        $founds[$userObj->screen_name] = true;
    }

    return $founds;
}
