PHP从字符串中删除特殊字符并留下一些

Question

I need to remove all special characters from string except - ( )

I have this code so far

$q = preg_replace('/[^A-Za-z0-9\-]/', '', $q); //removes ALL characters

how to exclude - ( ) ?

Answer 1

You should try something like

$q = preg_replace('/[^A-Za-z0-9\-\(\) ]/', '', $q); //removes ALL characters

The above will allow spaces, (, ) as well as -.
