I'm trying to use the Twitter API in PHP to list tweets that match a hashtag:
$url = 'https://api.twitter.com/1.1/search/tweets.json';
$count = 3;
$hashtag = '#twitter';
$oauth = array(
'oauth_consumer_key' => '##########',
'oauth_nonce' => hash('SHA1', time()),
'oauth_signature' => '',
'oauth_signature_method' => 'HMAC-SHA1',
'oauth_timestamp' => time(),
'oauth_token' => '##########',
'oauth_version' => '1.0'
);
$oauth_vals[] = "q={$hashtag}";
foreach ($oauth as $key => $value)
{
if (empty($value)) continue;
$oauth_vals[] = "{$key}={$value}";
}
$oauth_vals[] = "count={$count}";
$base = 'GET&' . rawurlencode($url) . '&' . rawurlencode(implode('&', $oauth_vals));
$composite_key = rawurlencode('##########') . '&' . rawurlencode('##########');
$oauth_signature = base64_encode(hash_hmac('sha1', $base, $composite_key, true));
$oauth['oauth_signature'] = rawurlencode($oauth_signature);
foreach ($oauth as $key => $value)
{
$auth_header[] = "{$key}=\"{$value}\"";
}
$auth_header = implode(', ', $auth_header);
$options = array(
CURLOPT_HTTPHEADER => array("Authorization: OAuth {$auth_header}"),
CURLOPT_HEADER => false,
CURLOPT_URL => "https://api.twitter.com/1.1/search/tweets.json?q={$hashtag}&count={$count}",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_HTTPGET => true
);
$feed = curl_init();
curl_setopt_array($feed, $options);
$json = curl_exec($feed);
curl_close($feed);
$tweets = json_decode($json, true);
var_dump($tweets); exit;
But I get this error:
array(1) { ["errors"]=> array(1) { [0]=> array(2) { ["message"]=> string(26) "Could not authenticate you" ["code"]=> int(32) } } }
What have I done wrong? All the tokens and keys are correct from my apps section on Twitter... so can't understand why I'm getting this error.
If I do: https://api.twitter.com/1.1/statuses/user_timeline.json?count={$count}&screen_name={$screen_name}
then it works.. so perhaps I'm using incorrect code for the search api?

Well I'm not sure what was wrong with my code, but using this:
https://github.com/J7mbo/twitter-api-php
works great, so I'd recommend using this code if anyone wants to use the Twitter API.
Apparently the parameters MUST be alphabetical order, e.g. count=1&q=#twitter
