Question

php curl默认链接超时时间是多少

Answer 1

1. curl代码如下

   123456789101112131415161718192021222324

   /**     * curl操作     * @param unknown_type $pURL     * @param unknown_type $pPostData     * @return unknown     */    public static function getURLContent($pURL, $pPostData = '') {        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $pURL);        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 1); // 连接超时（秒）        curl_setopt($ch, CURLOPT_TIMEOUT, 3); // 执行超时（秒）             if($pPostData) {            curl_setopt($ch, CURLOPT_POST, 1);            curl_setopt($ch, CURLOPT_POSTFIELDS, $pPostData);        }             $out_put = curl_exec($ch);        curl_close($ch);             return $out_put;    }

2. 理论是可以设置无限长的时间，但实际操作中不可能这样做，可根据实际情况设置

   curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 1); // 连接超时（秒）
   curl_setopt($ch, CURLOPT_TIMEOUT, 3); // 执行超时（秒）

Answer 2

global $g_handle;
if (empty($g_handle)) $ch = curl_init();
$options = array(
CURLOPT_URL => $url,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_FRESH_CONNECT => false,
CURLOPT_FORBID_REUSE => false,
CURLOPT_TIMEOUT => $timeout
);
curl_setopt_array($g_handle, $options);
$ret = curl_exec($g_handle);
return $ret;
}
