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., (*3)
<?php
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., (*4)
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)., (*5)
<?php
use LitGroup\Str\RegExp;
$emailPattern = new RegExp('/^\w+(?:[-+.\']\w+)*@\w+(?:[-.]\w+)*\.\w+(?:[-.]\w+)*$/Dsu');
if ($emailPattern->isSatisfiedBy('john@example.com')) {
echo 'This is a valid email address!';
}
