我试图创建一个PHP脚本，它可以从外部服务器请求数据，如HTML内容，然后对接收到的内容做一些事情。下面是我试图实现的一个通用示例:

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;

我在想我应该在这里的某个地方使用curl，但我不确定之后。有人能发布一个通用的例子来说明我是如何做到这一点的吗？

顺晟科技：

如果您只需要GET，并且在服务器上启用了GET，则可以简单地使用

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;

如果您的PHP安装不支持curl，并且不支持curl，这里有一个选项，如果您有pecl:

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;

简单地说:

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;

简单方法

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;

最佳方法（使用卷曲）:

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;

这就是如何使用curl从远程URL获取内容。您可以定义函数并进行类似

的调用

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;

//Get the HTML generated by http://api.somesite.com/

//Now tack on the Unix timestamp of when the data was received
$myFetchedData = $dataFromExternalServer . "\n Data received at: ". time();

echo $myFetchedData;
