In a project of mine, I'm having a few upload forms. Since I live in Sweden, I want to encode the Swedish special characters to their respective HTML-code, so that encoding won't be an issue when displaying the data. Here's the code:
function format_text($text){
$chars = ['å','ä','ö','Å','Ä','Ö'];
$codes = ['å','ä','ö','Å','Ä','Ö'];
foreach($chars as $key => $value){
$text = str_replace($value,$codes[$key],$text);
}
$text = str_replace("","
",$text);
$text = preg_replace("!
+!", "
", $text);
$text = htmlspecialchars($text, ENT_QUOTES, 'UTF-8');
$lines = explode("
", $text);
foreach ($lines as $key => $line){
$lines[$key] = "<p>{$line}</p>";
}
$text = implode("
", $lines);
return $text;
}
Anyway, after running this function I always get an empty string from the htmlspecialchars
, which I've understood is because of the Swedish special chars which is never replaced. So, my question is this: Why isn't the special chars replaced with it's respective HTML-code, and how can I fix it? I'm using PHP5.4.
