# Syntax
|
|
|
|
## Working with strings
|
|
|
|
``` php
|
|
use Symfony\Component\String\ByteString;
|
|
use Symfony\Component\String\CodePointString;
|
|
use Symfony\Component\String\UnicodeString;
|
|
|
|
$content = new CodePointString('Hello world');
|
|
$content = new UnicodeString('नमस्ते दुनिया');
|
|
$content = new ByteString('さよなら');
|
|
|
|
$content = (new CodePointString('hello'))->toUnicodeString();
|
|
$content = UnicodeString::fromCodePoints(0x68, 0x65, 0x6C, 0x6C, 0x6F)->toByteString();
|
|
```
|
|
|
|
``` php
|
|
use function Symfony\Component\String\b;
|
|
use function Symfony\Component\String\u;
|
|
|
|
// both are equivalent
|
|
$content = b('hello');
|
|
$content = new ByteString('hello');
|
|
|
|
// both are equivalent
|
|
$content = u('hello');
|
|
$content = new UnicodeString('hello');
|
|
```
|
|
|
|
## Object-oriented strings
|
|
|
|
``` php
|
|
// using PHP functions
|
|
if ('.html' === substr($theString, -strlen('.html'))) {
|
|
// ...
|
|
}
|
|
|
|
// using Symfony's String
|
|
if (u($theString)->endsWith('.html')) {
|
|
// ...
|
|
}
|
|
```
|
|
|
|
``` php
|
|
$text =u('This is a déjà-vu situation.')
|
|
->trimEnd('.')
|
|
->replace('déjà-vu', 'jamais-vu')
|
|
->append('!');
|
|
// $text = 'This is a jamais-vu situation!'
|
|
```
|
|
|
|
``` php
|
|
u('FOO Bar')->folded(); // 'foo bar'
|
|
u('Die O\'Brian Straße')->folded(); // "die o'brian strasse"
|
|
```
|
|
|
|
## String Slugger
|
|
|
|
``` php
|
|
use Symfony\Component\String\Slugger\AsciiSlugger;
|
|
|
|
$slugger = new AsciiSlugger();
|
|
$slugger->slug('Стойността трябва', '-', 'bg'); // 'Stoinostta-tryabva'
|
|
$slugger->slug('Αυτή η τιμή πρέπει', '-', 'el'); // 'Avti-i-timi-prepi'
|
|
$slugger->slug('该变量的值应为', '-', 'zh'); // 'gai-bian-liang-de-zhi-ying-wei'
|
|
$slugger->slug('Wôrķšƥáçè sèťtïñğš'); // 'Workspace-settings'
|
|
```
|
|
|
|
## Twig Integration
|
|
|
|
``` twig
|
|
{{ 'Lorem ipsum'|u.truncate(8, '...') }}
|
|
{# prints: Lorem... #}
|
|
|
|
{{ 'SymfonyStringWithTwig'|u.snake }}
|
|
{# prints: symfony_string_with_twig #}
|
|
```
