Convert Accented Characters to HTML Entities in PHP

- 1 minute read

This PHP function uses the built-in htmlentities function to convert the accented characters in a given string to HTML entities:

function accentedToHtml($str) {
    $html = htmlentities($str, 0, 'UTF-8');
    if ($html === '') {
        $html = htmlentities(utf8_encode($str), 0, 'UTF-8');
    return $html;

Here is some example usage:

$str = "éxample";
$html = accentedToHtml($str);

After the above code has run, $html will equal éexample.
