PHP是怎么处理异常的？像下面这样的代码，如何得知是执行成功了还是失败了？

    public function get_user($ch, $apikey) {
        \Think\Log::record('into get_user...');
        curl_setopt($ch, CURLOPT_URL, 'https://sms.xxx.com/v2/user/get.json');
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array('apikey' => $apikey)));

        $response = curl_exec($ch);
        \Think\Log::record('$response : '.$response);
        if (false === $response) {
            die(curl_error);
        }
        return $response;
    }

在一个项目里面, 你很难保证curl发出的http请求一定是正确并且在超时范围内返回的..反而是经常出问题的.
所以为了项目后面的代码能正确处理curl遇到的错误, 我认为抛出异常是最好的方式.
```
$response = curl_exec($ch);
if (false === $response) {
    die(curl_error($ch));
    throw new Exception(curl_error($ch),curl_errno($ch));
}
```

补充 @incNick 的答案，PHP 7 版本，异常多了异常类 Error ，跟 Exception 是平级关系
可以参考
1、http://php.net/manual/zh/migration70.incompatible.php
2、http://php.net/manual/zh/language.errors.php7.php

阳光卐誓言

抛出异常 throw new Exception()
可能触发异常的代码 try{...}
捕获异常 catch(Exception $e){}

补充:

protected function curl($url, $postFields = null)
{
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 5.01; Windows NT 5.1)');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FAILONERROR, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//curl_setopt($ch,CURLOPT_HTTPHEADER,array('Expect:'));
if (is_array($postFields) && 0 < count($postFields))
{
$postBodyString = '';
$postMultipart = false;
foreach ($postFields as $k => $v)
{
if('@' != substr($v, 0, 1))//判断是不是文件上传
{
$postBodyString .= '$k=' . urlencode($v) . '&';
}
else//文件上传用multipart/form-data，否则用www-form-urlencoded
{
$postMultipart = true;
}
}
unset($k, $v);
curl_setopt($ch, CURLOPT_POST, 1);
if ($postMultipart)
{
cur l_setopt($ch, CURLOPT_POSTFIELDS, $postFields);
}
else
{
//var_dump($postBodyString);
curl_setopt($ch, CURLOPT_POSTFIELDS, substr($postBodyString,0,-1));
}
}
$reponse = curl_exec($ch);
//return curl_getinfo($ch);
if (curl_errno($ch))
{
throw new Exception(curl_error($ch),0);
}
else
{
$httpStatusCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if (200 !== $httpStatusCode)
{
throw new Exception($reponse,$httpStatusCode);
}
}
curl_close($ch);
return $reponse;
}

木桌上的年轮_1

$apiKey = '';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://sms.yunpian.com/v2/user/get.json');
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array('apikey' => $apiKey)));
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
$response = curl_exec($ch);
if (false === $response) {
    die(curl_error($ch));
}
print_r($response);

自己运行调试吧，不解释了。
