file_get_contents() converts UTF-8 to ISO-8859-1
Solution 1
This seems to be a content negotiation problem as file_get_contents
probably sends a request that only accepts ISO 8859-1 as character encoding.
You can create a custom stream context for file_get_contents
using stream_context_create
that explicitly states that you accept UTF-8:
$opts = array('http' => array('header' => 'Accept-Charset: UTF-8, *;q=0'));
$context = stream_context_create($opts);
$filename = "http://search.yahoo.com/search;_ylt=A0oG7lpgGp9NTSYAiQBXNyoA?p=naj%C5%A1%C5%A5astnej%C5%A1%C3%AD&fr2=sb-top&fr=yfp-t-701&type_param=&rd=pref";
echo file_get_contents($filename, false, $context);
Solution 2
file_get_contents should not change the charset. The data is pulled in as a binary string.
When checking out the url you provided, this is the header it provides:
Content-Type: text/html; charset=ISO-8859-1
Also, in the body:
<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">
Also, you can't convert UTF-8 losslessly convert to ISO-8859-1 and get the characters back when going back to UTF-8. UTF-8 / unicode supports many many more characters, so the characters are lost in the first step.
In the browser this is not the case, so perhaps you just need to provide a correct Accept-Encoding header to instruct yahoo's system you can accept UTF-8.
Solution 3
For anyone investigating on this:
The time I spent on encoding issues taught me that rarely php functions "magically" change the encoding of strings. (One of these rare examples is :
exec( $command, $output, $returnVal )
Please note also that the working header set is as follows:
header('Content-Type: text/html; charset=utf-8');
and not:
header('Content-Type: text/html; charset=UTF-8');
As I had a similar issue as the one you describe, it was enough to set the headers properly.
Hope this helps!
Solution 4
$s2 = iconv("ISO-8859-1","UTF-8//TRANSLIT//IGNORE",$filename );
Better solution...
function curl($url){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_ENCODING, 1);
return curl_exec($ch);
curl_close($ch);
}
echo curl($filename);

I am trying to get search results from yahoo.com.
But file_get_contents() converts UTF-8 charset (charset, that yahoo uses) content to ISO-8859-1.
Try:
$filename = "http://search.yahoo.com/search;_ylt=A0oG7lpgGp9NTSYAiQBXNyoA?p=naj%C5%A1%C5%A5astnej%C5%A1%C3%AD&fr2=sb-top&fr=yfp-t-701&type_param=&rd=pref"; echo file_get_contents($filename);
Scripts as
header('Content-Type: text/html; charset=UTF-8');
or
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
or
$er = mb_convert_encoding($filename , 'UTF-8');
or
$s2 = iconv("ISO-8859-1","UTF-8",$filename );
or
echo utf8_encode(file_get_contents($filename));
NOT help, because after getting web content speciall characters as š ť ž are replaced with question marks ???
I would appreciate any kind of help.

vladinko0 about 13 yearsHow did you find out
Content-Type: text/html; charset=ISO-8859-1
and<meta http-equiv="content-type" content="text/html; charset=ISO-8859-1">
When I look in source code of that page I see<!doctype html><html lang="en"><head><meta http-equiv="content-type" content="text/html; charset=UTF-8">
-
Dejan Marjanović about 13 years@vladinko0, I think you need to set
CURLOPT_FOLLOWLOCATION
, I've updated my answer, try again. -
vladinko0 about 13 yearsNow it loads the page, but with the same result as with file_get_contents() it means with question marks. Charset is also converted to ISO-8859-1.
-
Dejan Marjanović about 13 yearsIt seems that yahoo.com is serving different pages (charsets) depending on your IP (country). I changed your URL to
http://ru.search.yahoo.com
but it doesn't work. Maybe you can achieve something with accept charset headers,refuse ISO-8859-1... -
Dejan Marjanović about 13 yearsIt serves different encoding based on your location, you could try fetching page using Russian proxy servers.
-
Dejan Marjanović about 13 yearsFunny thing, I tried
Accept-Charset=utf-8;q=0.7,*;q=0.7
, but doesn't work :) -
Gumbo about 13 years@webarto: The value
utf-8;q=0.7,*;q=0.7
is likeutf-8,*
and would accept any character encoding equally. -
Craig Morgan about 10 yearsNice one Gumbo! I was struggling with umlauts in the url (München) - this solved the problem. Thanks!
