Why Does file_get_contents() Corrupt Special Characters in Remote HTML, and How Can I Fix It?

File_get_contents() Breaks XML Formatting in HTML

When using file_get_contents() to retrieve content from a remote HTML document, some special characters may malfunction. This occurs primarily with content encoded in UTF-8 that involves characters such as Ľ, Š, Č, Ť, Ž, and others. Instead of rendering properly, these characters display corrupted versions such as Å, ¾, ¤, and similar nonsensical symbols.

Solution:

To resolve this issue, convert the retrieved content to HTML entities using the mb_convert_encoding() function. Here's the modified code:

<!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');
$convertedHtml = mb_convert_encoding($html, 'HTML-ENTITIES', "UTF-8");
echo $convertedHtml;

?>

</body>
</html>

Copy after login

By converting the UTF-8 characters to their corresponding HTML entities, we ensure proper rendering of special characters in the loaded HTML document.
