# NoWhitespace
|
||
|
|
|
||
|
|
- `v::noWhitespace()`
|
||
|
|
|
||
|
|
Validates if a string contains no whitespace (spaces, tabs and line breaks);
|
||
|
|
|
||
|
|
```php
|
||
|
|
v::noWhitespace()->validate('foo bar'); //false
|
||
|
|
v::noWhitespace()->validate("foo\nbar"); // false
|
||
|
|
```
|
||
|
|
|
||
|
|
This is most useful when chaining with other validators such as `v::alnum()`
|
||
|
|
