How can the html_entity_decode function be used to convert a variable from Windows-1251 to KOI8-R encoding?
To convert a variable from Windows-1251 to KOI8-R encoding in PHP, you can use the html_entity_decode function with the appropriate charset parameter specified. This function will decode HTML entities in the string, effectively converting it to the desired encoding. By setting the charset parameter to Windows-1251, the function will decode the string from Windows-1251 encoding to its original form, and then you can encode it to KOI8-R encoding.
// Input variable encoded in Windows-1251
$input = "Some text in Windows-1251 encoding";
// Convert the variable from Windows-1251 to KOI8-R encoding
$output = iconv('Windows-1251', 'KOI8-R', html_entity_decode($input, ENT_QUOTES, 'Windows-1251'));
echo $output;
