Example of usage

UTF-8 String Manipulation

There is the class Str, which contains collection of methods for string manipulation. This methods use mb_string internally, but you should'n be worried of encoding. Str methods always work with the UTF-8 encoding.


use LitGroup\Str\Str;

Str::length('hello'); // => 5
Str::isEmpty('hello'); // => false
Str::isNotEmpty('hello'); // => true
Str::trim(' hello '); // => 'hello'
// ...

Check the code to see all methods.

Using Patterns

From time to time you need to check that a string matches to the pattern. For this purpose, this library provides the Pattern interface. RegExp is one implementation of Pattern, which represents Perl-Compatible Regular Expressions (PCRE).


use LitGroup\Str\RegExp;

$emailPattern = new RegExp('/^\w+(?:[-+.\']\w+)*@\w+(?:[-.]\w+)*\.\w+(?:[-.]\w+)*$/Dsu');

if ($emailPattern->isSatisfiedBy('')) {
    echo 'This is a valid email address!';
