Trying to extract some keywords from urldecode($_SERVER['HTTP_REFERER'])…

Then $ref = preg_split("/[\s]+/", $referer);

Usually, it works fine with western languages, but I often have issues to separate words with Asian languages like here :

すずめ　焼き, বন মুরগির,

same issue in Hebrew !

Is there anything more universal than \s in regexp? Or should I handle HTTP_REFERER differently?

It is a very common thing, use `"/\s+/u"` – Wiktor Stribiżew May 14 '19 at 10:07
So common… makes you wonder why it's not enabled by default, by now ? Thanks. – S.E. May 14 '19 at 11:13
If you do not want to match any Unicode digit with `\d` or any digit or letter with `\w`, the `u` modifier should not be used. See more [here](https://www.php.net/manual/en/reference.pcre.pattern.modifiers.php). – Wiktor Stribiżew May 14 '19 at 11:16
