我希望能够做到以下几点:
$search_terms[0]='frank';
$search_terms[1]='sinatra';
$search_terms[2]='beyonce';
foreach($search_terms as $term){
$ch = curl_init();
$url ='http://search.twitter.com/search.json?q=' + $term +'&rpp=100';
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
$var = curl_exec($ch);
curl_close($ch);
$obj = json_decode($var, true);
echo $term;
var_dump($obj);
}
但是当我转储$ obj时,我得到一个NULL对象,即使$ term打印正常。

您应该使用.
而不是+
:
$url ='http://search.twitter.com/search.json?q=' . $term . '&rpp=100';
