Misc

String conversion

use Symfony\Component\String\ByteString;
use Symfony\Component\String\CodePointString;
use Symfony\Component\String\UnicodeString;

$content=newCodePointString{(}^{\prime }Helloworl{d}^{\prime });$content = new UnicodeString(‘नमस्ते दुनिया’);
$content = new ByteString(‘さよなら’);

$content=(newCodePointString{(}^{\prime }hell{o}^{\prime }))->toUnicodeString();$content = UnicodeString::fromCodePoints(0x68, 0x65, 0x6C, 0x6C, 0x6F)->toByteString();

use function Symfony\Component\String\b;
use function Symfony\Component\String\u;

// both are equivalent
$content=b{(}^{\prime }hell{o}^{\prime });$content = new ByteString(‘hello’);

// both are equivalent
$content=u{(}^{\prime }hell{o}^{\prime });$content = new UnicodeString(‘hello’);

Object-oriented strings

// using PHP functions
if (‘.html’ === substr($theString, -strlen(‘.html’))) {
// …
}

// using Symfony’s String
if (u($theString)->endsWith(‘.html’)) {
// …
}

$text=u{(}^{\prime }Thisisad\acute{e}j\grave{a}-vusituation{.}^{\prime })->trimEnd{(}^{\prime }{.}^{\prime })->replace{(}^{\prime }d\acute{e}j\grave{a}-v{u}^{\prime }{,}^{\prime }jamais-v{u}^{\prime })->append{(}^{\prime }{!}^{\prime });//$text = ‘This is a jamais-vu situation!’

u(‘FOO Bar’)->folded(); // ‘foo bar’
u(‘Die O’Brian Straße’)->folded(); // “die o’brian strasse”

String Slugger

use Symfony\Component\String\Slugger\AsciiSlugger;

$slugger=newAsciiSlugger();$slugger->slug(‘Стойността трябва’, ’-’, ‘bg’); // ‘Stoinostta-tryabva’
$slugger->slug{(}^{\prime }A\upsilon \tau \acute{\eta }\eta \tau \iota \mu \acute{\eta }\pi \rho \acute{\epsilon }\pi \epsilon {\iota }^{\prime }{,}^{\prime }{-}^{\prime }{,}^{\prime }e{l}^{\prime });/{/}^{\prime }Avti-i-timi-prep{i}^{\prime }$slugger->slug(‘该变量的值应为’, ’-’, ‘zh’); // ‘gai-bian-liang-de-zhi-ying-wei’
$slugger->slug(‘Wôrķšƥáçè sèťtïñğš’); // ‘Workspace-settings’
