如何捕获PHP中的curl错误 [英] How to catch curl errors in PHP

问题描述

我使用PHP的 curl 函数将数据从本地计算机发布到Web服务器。我的代码如下：

I am using PHP's curl functions to post data to the web server from my local machine. My code is as follows:

$c = curl_init();
curl_setopt($c, CURLOPT_URL, $url);
curl_setopt($c, CURLOPT_RETURNTRANSFER,true);
curl_setopt($c, CURLOPT_POST, true);
curl_setopt($c, CURLOPT_POSTFIELDS, $data);
$result=curl_exec ($c);

if(curl_exec($c) === false) {
    echo "ok";
}
else {
    echo "error";
}

curl_close ($c);

很遗憾，我无法捕获404,500或网络故障等错误。

Unfortunately I am not able to catch any errors like 404, 500 or network failure. So how will I get to know that data was not posted to or retrieved from the remote?

推荐答案

您可以使用 curl_error（）函数知道是否有错误，例如：

You can use the curl_error() function to know if there was some error, example:

if(curl_error($c))
{
    echo 'error:' . curl_error($c);
}
