A a french developer, I often come across non-ASCII characters in user-input data. In order to generate clean, search friendly equivalents, I created the following function that removes the accents while preserving the string integrity.
Example
$str = "À l'île, en été, quelle félicité !";
echo accent2ascii($str); // A l'ile, en ete, quelle felicite
The function
/**
* Converts accentuated characters (àéïöû etc.)
* to their ASCII equivalent (aeiou etc.)
*
* @param string $str
* @param string $charset
* @return string
*/
function accent2ascii(string $str, string $charset = 'utf-8'): string
{
$str = htmlentities($str, ENT_NOQUOTES, $charset);
$str = preg_replace('#&([A-za-z])(?:acute|cedil|caron|circ|grave|orn|ring|slash|th|tilde|uml);#', '\1', $str);
$str = preg_replace('#&([A-za-z]{2})(?:lig);#', '\1', $str); // pour les ligatures e.g. 'œ'
$str = preg_replace('#&[^;]+;#', '', $str); // supprime les autres caractères
return $str;
}
Don't forget to leave a like to encourage me to post more useful PHP snippets.

If the "intl" php extension is not installed or you need something language specific you can also use this package: github.com/voku/portable-ascii
Nice job you did there!
