正则表达式为人们命名PHP

Question

I am using this regex to make sure that names can only contain letters, apostrophe or hyphen.

Validator::extend('people_names', function($attribute, $value, $parameters, $validator) {
        return preg_match("^[a-zA-Z-'\s]+$^", $value);

When I use this tool to check if the regex is correct, it shows its correct, but in my form when I test an input starting with digits or any other characters like 123name or #$#$name it passes while it should not. An input with letters then digits like name123 is rejected.

Answer 1

The PHP preg_ functions need to start with /^ and end with $/.

Try this:

preg_match("/^[a-zA-Z-'\s]+$/", $value);
