【问题描述】：
我有一张桌子，里面有大约 20000 个未处理的 Youtube 帖子。 这个表是使用一个可以正常工作的 cronjob 自动填充的。 现在我有一个代码，它应该只有在处理完所有帖子后才会退出。
为此，我必须使用 curl 从 youtube 获取更多信息。 我的代码运行良好，但是在随机的时间/帖子之后，我收到了一个致命错误：
PHP 致命错误：超过 30 秒的最大执行时间 /home/local/domains/domain.com/private/include/classes/Youtube.php 上 第 183 行
这是代码：
public function api_get($url, $params)
{
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
//set the youtube key
$params["key"] = $this->youtube_key;
//boilerplates for CURL
$tuCurl = curl_init();
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
curl_setopt_array($tuCurl, array(
CURLOPT_URL => $url . (strpos($url, "?") === false ? "?" : "") . http_build_query($params),
CURLOPT_PORT => strpos($url, "https") === false ? 80 : 443,
CURLOPT_CONNECTTIMEOUT => 30,
CURLOPT_FRESH_CONNECT => true,
CURLOPT_FORBID_REUSE => true,
CURLOPT_TIMEOUT => 60,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_MAXREDIRS => 5,
CURLOPT_NOPROGRESS => false // only for debugging purposes
));
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
$tuData = curl_exec($tuCurl);
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
if (curl_errno($tuCurl)) {
$curlError = curl_error($tuCurl);
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
curl_close($tuCurl);
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
throw new Elision("[#505011] "._("Curl Error:")." ". $curlError);
}
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
curl_close($tuCurl);
error_log(__FILE__."::".__LINE__." - ".date("U"), 0);
return $tuData;
}
我使用error_log 找出问题出在哪里，当我使用 SSH 运行此代码时，我得到了这个（我只显示最后几行）：

如您所见，相同的代码运行良好，但下一次它不会运行并产生致命错误。 当我重新运行脚本时，它也会随机运行一段时间，然后再次崩溃，因此它不能是输入 url。
任何想法如何解决这个问题，我没有得到致命错误？
编辑：
我忘了补充：
函数 api_get 在类Youtube.php 中。
我从名为youtube_parsing.php 的文件中运行此代码。
在youtube_parsing.php 我有这个来避免执行限制：
set_time_limit(0);
ini_set("max_execution_time", 0);
【问题讨论】：
-
可能是网络延迟问题。您是否尝试在 curl 代码中增加此设置？
CURLOPT_CONNECTTIMEOUT => 30你也可以尝试使用set_time_limit()增加PHP执行时间限制@ -
我已经尝试了各种值，但我并不真正关心 curl 是否失败，我只想编写代码继续，而不是得到一个致命的错误来停止一切。
-
Youtube.php 的第 183 行是什么？看起来它在某个地方有一个 PHP 最大时间限制，它在达到 curl 限制之前就已经达到了。但奇怪的是，您无论如何都避免了执行限制。
-
如果您在 youtube_parsing 中执行 foreach，请尝试将 set_time_limit(0) 放在循环顶部，以便每次都重置时间限制。
-
@gazareth，第 183 行只不过是
curl_exec。我将set_time_limit放在foreach 循环中。我认为这不是一个很好的方法，将它放在上面会更好，但它似乎可以解决问题。
