我在本地有一個問題（Fedora），我沒有在我的服務器（RedHat）上看到問題。當在apache下運行的腳本中使用php的curl函數時，我無法連接到HTTPS服務器。當我從CLI運行完全一樣的腳本時，它沒有任何連接問題。連接到HTTP服務器沒有問題，只能連接到HTTPS。當我在RedHat服務器上運行完全相同的腳本時，它在apache和CLI下運行良好。PHP的libcurl無法連接到https站點
這裏的腳本：
<?php
$ch = curl_init();
curl_setopt_array($ch, [
CURLOPT_URL => "https://www.google.com/",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_VERBOSE => true,
]);
$result = curl_exec($ch);
$headers = curl_getinfo($ch);
echo "Result:\n";
var_export($result);
echo "\n\nHeaders:\n";
var_export($headers);
?>
當我apache下運行它，我得到這個輸出：
Result:
false
Headers:
array (
'url' => 'https://www.google.com/',
'content_type' => NULL,
'http_code' => 0,
'header_size' => 0,

array (
),
'primary_port' => 443,
'local_ip' => '192.168.5.197',
'local_port' => 39900,
)
..而這在錯誤日誌：

任何想法？謝謝。這是PHP 5.5.7。
我應該提及/ bin/curl也可以，而且我試過設置CURLOPT_CAINFO，但是結果是一樣的。 – Greg
