zoeken en speciale characters
ik ben op zoek naar een manier om een tekst te doorzoeken met speciale characters.
bv. de zoekterm 'heel groot' moet niet alleen 'heel groot' geven, maar ook 'héél groot', 'heel gróót' en alle variaties daarop. (zoals Google het doet)
Moet ik zelf een workaround bouwen, bijvoorbeeld door alle speciale characters in zowel de zoekterm als de tekst tijdelijk te vervangen door 'normale' (bv áàâä => a) of is er een php-functie voor die ik nog nooit heb gevonden? :-)
alvast bedankt
Maar ook met htmlspecialchars (zie: http://php.net/manual/en/function.htmlspecialchars.php)
$string = str_replace("á","a",$string);
$string = str_replace("à","a",$string);
enz...?

Het is niet fraai geworden, maar het werkt wel: alle diakritische tekens worden omgezet naar hun 'normale' evenknie. Voor wie het kan gebruiken:
