php curl 抓取網頁 時好時壞

本來都能夠正常抓取
但前幾天開始,變的時好時壞
有時正常運行,有時跑了很久都跑不出來
但用瀏覽器訪問都正常

狀況網址之一: http://report.penghu.gov.tw/OpenFront/report/report_detail.jsp?sysId=C105AQ022

想請問可能是哪方面的原因
謝謝

...你要在curl_exec()之後再執行curl_getinfo()吧XD

這就是在curl_exec()執行的.....

更正:

主要想知道為何
[http_code] => 0
是否可能是請求時出了什麼問題?
現在請求成功率大約只有50%

我測試一下,沒看到問題...另外,curl_getinfo()要在curl_exec()之後執行啦,沒真的去連不會取得資訊阿。

簡單的測試:

<?php
$url = 'http://report.penghu.gov.tw/OpenFront/report/report_detail.jsp?sysId=C105AQ022';

$h = curl_init($url);
curl_setopt($h, CURLOPT_RETURNTRANSFER, true);
$c = curl_exec($h);
$i = curl_getinfo($h);
curl_close($h);
echo nl2br(print_r($i, true));

結果看起來算正常:

Array

[url] => http://report.penghu.gov.tw/OpenFront/report/report_detail.jsp?sysId=C105AQ022
