File_get_content()分解 UTF-8字符

我正在从外部服务器加载 HTML。HTML 标记具有 UTF-8编码并包含诸如、、等字符。当我使用 file _ get _ content ()加载 HTML 时，如下所示:

$html = file_get_contents('http://example.com/foreign.html');

它搞乱了 UTF-8字符并加载 Å，3.4和类似的废话，而不是正确的 UTF-8字符。

我该怎么解决这个问题？

更新:

我尝试将 HTML 保存到一个文件中并用 UTF-8编码输出它。两者都不能工作，因此这意味着 file _ get _ content ()已经返回了破碎的 HTML。

更新2:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="sk" lang="sk">
<head>


<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta http-equiv="Content-Style-Type" content="text/css" />
<meta http-equiv="Content-Language" content="sk" />
<title>Test</title>


</head>
<body>




<?php


$html = file_get_contents('http://example.com');
echo htmlentities($html);


?>


</body>
</html>

Solution suggested in the comments of the PHP manual entry for file_get_contents

function file_get_contents_utf8($fn) {
$content = file_get_contents($fn);
return mb_convert_encoding($content, 'UTF-8',
mb_detect_encoding($content, 'UTF-8, ISO-8859-1', true));
}

You might also try your luck with http://php.net/manual/en/function.mb-internal-encoding.php

Alright. I have found out the file_get_contents() is not causing this problem. There's a different reason which I talk about in another question. Silly me.

See this question: Why Does DOM Change Encoding?

I think you simply have a double conversion of the character type there :D

It may be, because you opened an html document within a html document. So you have something that looks like this in the end

<!DOCTYPE html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title></title>
</head>
<body>
<!DOCTYPE html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Test</title>.......

The use of mb_detect_encoding therefore may lead you to other issues.

I had similar problem with polish language

I tried:

$fileEndEnd = mb_convert_encoding($fileEndEnd, 'UTF-8', mb_detect_encoding($fileEndEnd, 'UTF-8', true));

I tried:

$fileEndEnd = utf8_encode ( $fileEndEnd );

I tried:

$fileEndEnd = iconv( "UTF-8", "UTF-8", $fileEndEnd );

And then -

$fileEndEnd = mb_convert_encoding($fileEndEnd, 'HTML-ENTITIES', "UTF-8");

This last worked perfectly !!!!!!

Try this too

 $url = 'http://www.domain.com/';
$html = file_get_contents($url);


//Change encoding to UTF-8 from ISO-8859-1
$html = iconv('UTF-8', 'ISO-8859-1//TRANSLIT', $html);

İn Turkish language, mb_convert_encoding or any other charset conversion did not work.

And also urlencode did not work because of space char converted to + char. It must be %20 for percent encoding.

This one worked!

   $url = rawurlencode($url);
$url = str_replace("%3A", ":", $url);
$url = str_replace("%2F", "/", $url);


$data = file_get_contents($url);

I am working with 35000 lines of data.

$f=fopen("veri1.txt","r");
$i=0;
while(!feof($f)){
$i++;
$line=mb_convert_encoding(fgets($f), 'HTML-ENTITIES', "UTF-8");
echo $line;
}

This code convert my strange characters into normal.

Exemple :

$string = file_get_contents(".../File.txt");
$string = mb_convert_encoding($string, 'UTF-8', "ISO-8859-1");
echo $string;

I had a similar problem, what solved it was html_entity_decode.

My code is:

$content = file_get_contents("http://example.com/fr");
$x = new SimpleXMLElement($content);
foreach($x->channel->item as $entry) {
$subEntry = html_entity_decode($entry->description);
}

In here I am retrieving an xml file (in French), that's why I'm using this $x object variable. And only then I decode it into this variable $subEntry.

I tried mb_convert_encoding but this didn't work for me.

Try this function

function mb_html_entity_decode($string) {
if (extension_loaded('mbstring') === true)
{
mb_language('Neutral');
mb_internal_encoding('UTF-8');
mb_detect_order(array('UTF-8', 'ISO-8859-15', 'ISO-8859-1', 'ASCII'));


return mb_convert_encoding($string, 'UTF-8', 'HTML-ENTITIES');
}


return html_entity_decode($string, ENT_COMPAT, 'UTF-8');

}

小开

I managed to solve using this function below:

function file_get_contents_utf8($url) {
$content = file_get_contents($url);
return mb_convert_encoding($content, "HTML-ENTITIES", "UTF-8");
}


file_get_contents_utf8($url);
