通过PHP检索网页内容的最简单方法是什么？

Question

I want to write a function to retrieve the contents of a webpage so it works like:

$url = "example.com";
$pageContent = RetrievePageContent($url);

What would be the easiest way to do this?

Thanks in advance for your help!

Answer 1

$pageContent = file_get_contents($url);

来自： file_get_contents

Answer 2

The easiest way is file_get_contents , which does exactly what you want:

$url = "http://example.com";
$pageContent = file_get_contents($url);

Answer 3

You can use the fopen command and pass it a URL. However, this ability might be disabled by your host. The best practice would be to use the cURL functions . The documentation includes sample code that does exactly what you're trying to do.
