curl_exec（）总是返回false [英] curl_exec() always returns false

问题描述

我写了这段简单的代码：

I have written this simple piece of code :

$ch = curl_init();

//Set options
curl_setopt($ch, CURLOPT_URL, "http://www.php.net");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$website_content = curl_exec ($ch);

在我的例子中 $ website_content code> false 。
任何人都可以建议/建议可能出现的错误？

In my case $website_content comes as false. Can anyone suggest/advice something what could be going wrong?

推荐答案

错误检查和处理是程序员的朋友。检查初始化和执行cURL函数的返回值。 curl_error（） 和< a href =http://www.php.net/manual/en/function.curl-errno.php> curl_errno（） 将包含进一步的失败时的信息：

Error checking and handling is the programmer's friend. Check the return values of the initializing and executing cURL functions. curl_error() and curl_errno() will contain further information in case of failure:

try {
    $ch = curl_init();

    if (FALSE === $ch)
        throw new Exception('failed to initialize');

    curl_setopt($ch, CURLOPT_URL, 'http://example.com/');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt(/* ... */);

    $content = curl_exec($ch);

    if (FALSE === $content)
        throw new Exception(curl_error($ch), curl_errno($ch));

    // ...process $content now
} catch(Exception $e) {

    trigger_error(sprintf(
        'Curl failed with error #%d: %s',
        $e->getCode(), $e->getMessage()),
        E_USER_ERROR);

}
