通过 CURL 循环查询链接并在 PHP 中合并结果数组

Question

下面的代码应该在 twitter 上搜索一个术语，循环遍历所有结果页面并返回一个大数组，并在每一步附加每个页面的结果。

foreach($search_terms as $term){
    //populate the obj array by going through all pages

    //set up connection
    $ch = curl_init();

    // go through all pages and save in an object array
    for($j=1; $j<16;$j++){
        $url ='http://search.twitter.com/search.json?q=' . $term .'&rpp=100&page='.$j.'';
        curl_setopt($ch, CURLOPT_URL,$url);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); 
        $var[$j] = curl_exec($ch);
        curl_close($ch);
        $obj = array_merge((array)$obj,(array)json_decode($var[$j], true));
    }
}

但它不太有效，并且出现以下错误：

curl_setopt(): 3 is not a valid cURL handle resource
curl_exec(): 3 is not a valid cURL handle resource
curl_close(): 3 is not a valid cURL handle resource
...... and this is repeated all the way from 3-> 7...
curl_setopt(): 7 is not a valid cURL handle resource
curl_exec(): 7 is not a valid cURL handle resource
curl_close(): 7 is not a valid cURL handle resource

Answer 1

//set up connection
$ch = curl_init();
// go through all pages and save in an object array

for($j=1; $j<16;$j++){

您需要在循环内调用curl_init()，因为您在每次迭代结束时关闭它。
