php - Curl 有时不会执行所有命令

Question

翼卷曲代码，我有很多preg_match_all();并获得一些数据和网址。有时它会处理所有内容，有时它会遗漏某些部分。

是否有任何功能可以让它等到所有卷曲完成或加快进程？

$ch = curl_init();

curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1); 
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file_path);   // Cookie management.
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file_path); 

$result = curl_exec($ch);

curl_close($ch); 

// Step3. parsing username
preg_match_all("#<span id=\"class\" class=\"tall\">(.*?)</span>#si", $result, $match);

那里有很多 preg_match_all命令
