php curl_exec 死掉并退出脚本并显示白屏

Question

这是我的代码:当我尝试连接到 whm/cpanel 以添加新帐户时，这个问题发生了，但是当我尝试从 whm/cpanel 中删除用户时，它工作得很好。我的问题是 curl_exec 线路死机并显示空白屏幕，页面上没有任何错误，并且在 curl_exec 根本没有运行后 curl_error 没有返回任何代码。

感谢您的回答

$curl = curl_init();
# Create Curl Object
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);
# Allow certs that do not match the domain
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);
# Allow self-signed certs
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
# Return contents of transfer on curl_exec
$header[0] = "Authorization: WHM $cpanel_user:" . preg_replace("'(\r|\n)'", "", $whmhash);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 1800);
# Remove newlines from the hash
curl_setopt($curl, CURLOPT_HTTPHEADER, $header);
# Set curl header
curl_setopt($curl, CURLOPT_URL, $command);
# Set your URL
curl_setopt($curl, CURLOPT_FAILONERROR, FALSE);

curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
if( ! $result = curl_exec($curl))
{
    trigger_error(curl_error($curl));
} 

$httpCode = curl_getinfo($curl, CURLINFO_HTTP_CODE);
# Execute Query, assign to $result
if ($result == false) {
    error_log("curl_exec threw error \"" . curl_error($curl) . "\" for $query");
}
curl_close($curl);

你应该使用 curl_errno 来检查 curl 是否有任何错误

替换这个

if( ! $result = curl_exec($curl))
{
    trigger_error(curl_error($curl));
} 

通过

$result = curl_exec($curl);
// Check for errors and display the error message
if($errno = curl_errno($curl)) {
    $error_message = curl_strerror($errno);
    trigger_error("cURL error ({$errno}):\n {$error_message}");
}
