php preg_replace all but alphanumeric, space and accented letters [duplicate]

Question

I want to strip a string from all characters, except for: Alphanumeric characters, spaces and accented letters.

I got it to work for everything except for the accented letters:

$fname = preg_replace("/[^\w\space/", "", $fname);

What do I need to change in order to allow accented letters in the output?

When I was struggling to get things working, I found the answer myself, so I decided to share it with you:

$fname = preg_replace("/[^\w\space\pL]/", "", $fname);

The "pL" part matches anything in the Unicode letter category, so accented letters are allowed in the output.

i found solution.

Accented letter

$str = 'paulraâj píc - accountant and knows Bilingüe';

Removing Accented letter

echo '<br>' .preg_replace('/[^a-zA-Z0-9_ -]/s', '', $str);

Result : paulraj pc - accountant and knows Bilinge

Please use this one :

$fname = preg_replace("/[^ \w]+/", "", $fname);
