I am learning PHP, and I'm trying to make an application that has a relationship with an external website.

I need to download it.

So I got this code:

$str = file_get_contents($url);

Which should return me the HTML contents of a website.开发者_如何学运维

it works fine for most websites, but for a particular one - http://www.fxp.co.il - it shows crap.

What is the problem ? What can I do to fix it ?

Thank you !

Well, you should actually inspect the response headers as they tell you about the encoding of the data returned file_get_contents.

For example, if it's gzip encoded, you need to uncompress it.

Normally you won't notice that because file_get_contents() sends a request in a way that the server knows that it does not support compression.

However some servers just do not care and send you compressed responses anyway:

<?php

$url = 'http://www.fxp.co.il/';

$buffer = file_get_contents($url);

echo $url, '<hr>', '<pre>', implode("\n", $http_response_header), '</pre>';

$bare = gzdecode($buffer);

echo '<hr>', htmlspecialchars(substr($bare, 0, 256));

Output:

http://www.fxp.co.il/
