You can use instead:
preg_replace('/\P{Xan}+/u', '', $string );
\p{Xan}
is all that is a number or a letter in any alphabet of the unicode table.
\P{Xan}
is all that is not a number or a letter. It is a shortcut for [^\p{Xan}]
質問
The most common regex suggested for removing special characters seems to be this -
preg_replace( '/[^a-zA-Z0-9]/', '', $string );
The problem is that it also removes non-English characters.
Is there a regex that removes special characters on all languages? Or the only solution is to explicitly match each special character and remove them?
