laravel validation rule to remove whitespaces

I want to validate a phone number. For example, one shouldn't able to store a number like the following: '07911 123456', '079 11123456', '0791112 345 6'.

What I've tried:

'number' => ['required', 'number', Rule::notIn('07911123456')],

I've already tried the regex rule(https://laravel.com/docs/6.x/validation#rule-regex), but it doesn't do exactly what I want. White spaces may allow but, the number which is not allowed shouldn't allow. No matter how many white spaces are included.

Before You post it to server You could remove whites-spaces:

number = '07911 123456';
number = number.replace(/\s/g, '');
var intNumber = parse.Int(number);

For php part You could use:

$number = preg_replace('/\s+/', '', $number);

you can trim the name input before validating it ....

in you request:

 public function rules()
    {
      $this->merge(['number'=>str_replace(' ', '',$this->input('number'))]);

       return [
        'number' => ['required', 'number', Rule::notIn(['07911123456'])],
        ];
}

Try this solution

if number filed is not array

<?php 

$validator = [   
    'number' => [
        'required',
        'regex:/^[0-9][0-9\s]+[0-9]$/',  // check number with white space
        function ($attribute, $value, $fail) {
            if ('07911123456' === \preg_replace('/\s+/', '', $value)) {
                $fail('Message fail');

                return false;
            }

            return true;
        }, 
    ],
// ... another rules
];

$validator = Validator::make($request->all(), $validator);

If number field is array

<?php


$validator = [
    'number' => [
        'required', 'array',
     ],
     'number.*' => [
        'regex:/^[0-9][0-9\s]+[0-9]$/',  // check number with white space
        function ($attribute, $value, $fail) {
            if ('07911123456' === \preg_replace('/\s+/', '', $value)) {
                $fail('Message fail');

                return false;
            }

            return true;
        },
     ],
// ... another rules
];

$validator = Validator::make($request->all(), $validator);

you can use laravel validation numeric

 'tlpn' => 'required|min:1|max:255|numeric|unique:data,tlpn',

Laravel 8 validation
