11.x 文字列 Laravel

イントロダクションIntroduction

Laravelには、文字列値を操作する様々な関数があります。これらの関数の多くはフレームワーク自体で使用されていますが、便利に感じるなら、あなたのアプリケーションでも自由にご利用ください。Laravel includes a variety of functions for manipulating string values. Many of these functions are used by the framework itself; however, you are free to use them in your own applications if you find them convenient.

文字列Strings

`()` `()`

__関数は、指定する翻訳文字列や翻訳キーを言語ファイルを使って翻訳します。The __ function translates the given translation string or translation key using your language files[/docs/{{version}}/localization]:

echo __('Welcome to our application');

echo __('messages.welcome');

指定した翻訳文字列や翻訳キーが存在しない場合、__関数は指定値をそのまま返します。たとえば、上記の場合に翻訳キーが存在しなければ、__関数はmessages.welcomeを返します。If the specified translation string or key does not exist, the __ function will return the given value. So, using the example above, the __ function would return messages.welcome if that translation key does not exist.

`class_basename()` `class_basename()`

class_basename関数は、指定クラスの名前から名前空間を取り除いて返します。The class_basename function returns the class name of the given class with the class's namespace removed:

// true

`Str::deduplicate()` `Str::deduplicate()`

Str::deduplicateメソッドは、指定文字列内の連続する文字を、その文字の単一のインスタンスに置き換えます。デフォルトでは、このメソッドはスペースを重複除去します：The Str::deduplicate method replaces consecutive instances of a character with a single instance of that character in the given string. By default, the method deduplicates spaces:

use Illuminate\Support\Str;

$result = Str::deduplicate('The   Laravel   Framework');

// The Laravel Framework

メソッドの第２引数に別の文字を渡せば、重複を排除する文字を指定できます。You may specify a different character to deduplicate by passing it in as the second argument to the method:

use Illuminate\Support\Str;

$result = Str::deduplicate('The---Laravel---Framework', '-');

use Illuminate\Support\Str;

$excerpt = Str::excerpt('This is my name', 'my', [
    'radius' => 3
]);

// '...is my na...'

radiusオプションはデフォルトが100で、抜き出した文字列の両側に表示する文字数を定義します。The radius option, which defaults to 100, allows you to define the number of characters that should appear on each side of the truncated string.

さらに、omissionオプションを使い、抜き出した文字列の前後に追加する文字列を定義できます。In addition, you may use the omission option to define the string that will be prepended and appended to the truncated string:

use Illuminate\Support\Str;

$excerpt = Str::excerpt('This is my name', 'name', [
    'radius' => 3,
    'omission' => '(...) '
]);

// '(...) my name'

// Email Notification Sent

`Str::inlineMarkdown()` `Str::inlineMarkdown()`

Str::inlineMarkdownメソッドは、GitHub仕様のMarkdownをCommonMarkにより、インラインHTMLへ変換します。しかし、markdownメソッドとは異なり、生成したすべてのHTMLをブロックレベルの要素中へラップはできません。The Str::inlineMarkdown method converts GitHub flavored Markdown into inline HTML using CommonMark[https://commonmark.thephpleague.com/]. However, unlike the markdown method, it does not wrap all generated HTML in a block-level element:

use Illuminate\Support\Str;

$html = Str::inlineMarkdown('**Laravel**');

// <strong>Laravel</strong>

Markdownの安全性Markdown Security

デフォルトでMarkdownは素のHTMLをサポートしており、ユーザー入力を直接使用すると、クロスサイト・スクリプティング（XSS）の脆弱性が生まれます。CommonMarkの安全性のドキュメントにあるように、html_inputオプションを使い、素のHTMLをエスケープ処理もしくは除去できます。また、allow_unsafe_linksオプションを使って安全でないリンクを許可するかも指定できます。素のHTMLを許可する必要がある場合は、コンパイル済みのMarkdownをHTML Purifierへ通す必要があります。By default, Markdown supports raw HTML, which will expose Cross-Site Scripting (XSS) vulnerabilities when used with raw user input. As per the CommonMark Security documentation[https://commonmark.thephpleague.com/security/], you may use the html_input option to either escape or strip raw HTML, and the allow_unsafe_links option to specify whether to allow unsafe links. If you need to allow some raw HTML, you should pass your compiled Markdown through an HTML Purifier:

use Illuminate\Support\Str;

Str::inlineMarkdown('Inject: <script>alert("Hello XSS!");</script>', [
    'html_input' => 'strip',
    'allow_unsafe_links' => false,
]);

// Inject: alert(&quot;Hello XSS!&quot;);

`Str::is()` `Str::is()`

Str::isメソッドは、指定文字列が指定パターンに一致するかどうかを判別します。アスタリスクをワイルドカード値として使用できます。The Str::is method determines if a given string matches a given pattern. Asterisks may be used as wildcard values:

$matches = Str::is('foo*', 'foobar');

// true

$matches = Str::is('baz*', 'foobar');

// false

`Str::isAscii()` `Str::isAscii()`

Str::isAsciiメソッドは、指定文字列が7ビットASCIIであるかを判定します。The Str::isAscii method determines if a given string is 7 bit ASCII:

// true

$isAscii = Str::isAscii('ü');

// false

`Str::isJson()` `Str::isJson()`

Str::isJsonメソッドは、指定文字列が有効なJSONであるかを判定します。The Str::isJson method determines if the given string is valid JSON:

use Illuminate\Support\Str;

$result = Str::isJson('[1,2,3]');

// true

$result = Str::isJson('{"first": "John", "last": "Doe"}');

// true

$result = Str::isJson('{first: "John", last: "Doe"}');

// false

`Str::isUrl()` `Str::isUrl()`

Str::isUrlメソッドは、指定文字列が有効なURLかを判定します。The Str::isUrl method determines if the given string is a valid URL:

use Illuminate\Support\Str;

$isUrl = Str::isUrl('http://example.com');

// true

$isUrl = Str::isUrl('laravel');

// false

isUrl メソッドは幅広いプロトコルを有効とみなします。しかし、isUrlメソッドへ有効なプロトコルを指定することもできます。The isUrl method considers a wide range of protocols as valid. However, you may specify the protocols that should be considered valid by providing them to the isUrl method:

$isUrl = Str::isUrl('http://example.com', ['http', 'https']);

`Str::isUlid()` `Str::isUlid()`

Str::isUlidメソッドは、指定文字列が有効なULIDであることを判定します。The Str::isUlid method determines if the given string is a valid ULID:

use Illuminate\Support\Str;

// true

$isUlid = Str::isUlid('laravel');

// false

`Str::isUuid()` `Str::isUuid()`

Str::isUuidメソッドは、指定した文字列が有効なUUIDであることを判定します。The Str::isUuid method determines if the given string is a valid UUID:

use Illuminate\Support\Str;

$isUuid = Str::isUuid('a0a2a2d2-0b87-4a18-83f2-2529882be2de');

// true

$isUuid = Str::isUuid('laravel');

// false

`Str::kebab()` `Str::kebab()`

Str::kebabメソッドは、指定した文字列をケバブケース（kebab-case）に変換します。The Str::kebab method converts the given string to kebab-case:

`Str::limit()` `Str::limit()`

Str::limitメソッドは、指定文字列を指定する長さへ切り捨てます。The Str::limit method truncates the given string to the specified length:

use Illuminate\Support\Str;

$truncated = Str::limit('The quick brown fox jumps over the lazy dog', 20);

// The quick brown fox...

メソッドに３番目の引数を渡し、切り捨てる文字列の末尾へ追加する文字列を変更できます。You may pass a third argument to the method to change the string that will be appended to the end of the truncated string:

$truncated = Str::limit('The quick brown fox jumps over the lazy dog', 20, ' (...)');

// The quick brown fox (...)

文字列を切り詰める際に完全な単語を保持したい場合は、preserveWords引数を使用します。この引数がtrueの場合、文字列を完全な単語に最も近い境界で切り捨てます。If you would like to preserve complete words when truncating the string, you may utilize the preserveWords argument. When this argument is true, the string will be truncated to the nearest complete word boundary:

$truncated = Str::limit('The quick brown fox', 12, preserveWords: true);

// The quick...

`Str::lower()` `Str::lower()`

Str::lowerメソッドは指定文字列を小文字に変換します。The Str::lower method converts the given string to lowercase:

Str::markdown('Inject: <script>alert("Hello XSS!");</script>', [
    'html_input' => 'strip',
    'allow_unsafe_links' => false,
]);

// <p>Inject: alert(&quot;Hello XSS!&quot;);</p>

`Str::mask()` `Str::mask()`

Str::maskメソッドは、文字列の一部を繰り返し文字でマスクし、メールアドレスや電話番号などの文字列の一部を難読化するために使用します。The Str::mask method masks a portion of a string with a repeated character, and may be used to obfuscate segments of strings such as email addresses and phone numbers:

use Illuminate\Support\Str;

$string = Str::mask('taylor@example.com', '*', 3);

// tay***************

必要であれば、maskメソッドの第３引数に負の数を指定し、文字列の最後から指定する文字数分戻った箇所からマスキングを開始するように指示できます。If needed, you provide a negative number as the third argument to the mask method, which will instruct the method to begin masking at the given distance from the end of the string:

$string = Str::mask('taylor@example.com', '*', -15, 3);

// tay***@example.com

`Str::orderedUuid()` `Str::orderedUuid()`

Str::orderedUuidメソッドは、インデックス付きデータベース列に効率的に格納できる「タイムスタンプファースト」UUIDを生成します。このメソッドを使用して生成した各UUIDは、以前にこのメソッドを使用して生成されたUUIDの後にソートされます。The Str::orderedUuid method generates a "timestamp first" UUID that may be efficiently stored in an indexed database column. Each UUID that is generated using this method will be sorted after UUIDs previously generated using the method:

$padded = Str::padRight('James', 10);

// 'James     '

`Str::password()` `Str::password()`

Str::passwordメソッドは、指定した長さの安全でランダムなパスワードを生成します。パスワードは文字、数字、シンボル、スペースの組み合わせで構成します。パスワードの長さは、デフォルトで３２文字です。The Str::password method may be used to generate a secure, random password of a given length. The password will consist of a combination of letters, numbers, symbols, and spaces. By default, passwords are 32 characters long:

use Illuminate\Support\Str;

$password = Str::password();

// 'EbJo2vE-AS:U,$%_gkrV4n,q~1xy/-_4'

$password = Str::password(12);

// 'qwuar>#V|i]N'

`Str::plural()` `Str::plural()`

Str::pluralメソッドは、単数形の単語文字列を複数形に変換します。この関数は、Laravelの複数形化機能により、どんな言語もサポートしています。The Str::plural method converts a singular word string to its plural form. This function supports any of the languages support by Laravel's pluralizer[/docs/{{version}}/localization#pluralization-language]:

use Illuminate\Support\Str;

$plural = Str::plural('car');

// cars

$plural = Str::plural('child');

// children

整数をこのメソッドの第２引数に指定することで、文字列の単数形と複数形を切り替えて取得できます。You may provide an integer as a second argument to the function to retrieve the singular or plural form of the string:

`Str::position()` `Str::position()`

Str::positionメソッドは、文字列内で部分文字列が最初に出現する位置を返します。部分文字列が指定した文字列内に存在しない場合は、falseを返します。The Str::position method returns the position of the first occurrence of a substring in a string. If the substring does not exist in the given string, false is returned:

use Illuminate\Support\Str;

$position = Str::position('Hello, World!', 'Hello');

// 0

$position = Str::position('Hello, World!', 'W');

// 7

`Str::random()` `Str::random()`

Str::randomメソッドは指定した長さのランダムな文字列を生成します。このメソッドは、PHPのrandom_bytes関数を使用します。The Str::random method generates a random string of the specified length. This function uses PHP's random_bytes function:

use Illuminate\Support\Str;

$random = Str::random(40);

テスト中に、Str::randomメソッドが返す値を「Fake」できると便利でしょう。これを行うには、createRandomStringsUsingメソッドを使用します。During testing, it may be useful to "fake" the value that is returned by the Str::random method. To accomplish this, you may use the createRandomStringsUsing method:

Str::createRandomStringsUsing(function () {
    return 'fake-random-string';
});

randomメソッドへ、通常通りのランダム文字列の生成に戻るよう指示するには、createRandomStringsNormallyメソッドを呼び出します。To instruct the random method to return to generating random strings normally, you may invoke the createRandomStringsNormally method:

Str::createRandomStringsNormally();

`Str::remove()` `Str::remove()`

Str::removeメソッドは、文字列から指定する値または値の配列を削除します。The Str::remove method removes the given value or array of values from the string:

use Illuminate\Support\Str;

    return $string->title();
});

// 'Laravel'

`whenNotExactly` `whenNotExactly`

whenNotExactlyメソッドは、文字列が指定文字列と厳密に一致しない場合に、指定クロージャを呼び出します。クロージャは、Fluent文字列インスタンスを受け取ります。The whenNotExactly method invokes the given closure if the string does not exactly match the given string. The closure will receive the fluent string instance:

use Illuminate\Support\Str;
use Illuminate\Support\Stringable;

$string = Str::of('framework')->whenNotExactly('laravel', function (Stringable $string) {
    return $string->title();
});

// 'Framework'

`whenIs` `whenIs`

whenIsメソッドは、文字列が与えられたパターンにマッチする場合、指定クロージャを呼び出します。アスタリスクはワイルドカードとして使用できます。クロージャはFluent文字列インスタンスを受け取ります。The whenIs method invokes the given closure if the string matches a given pattern. Asterisks may be used as wildcard values. The closure will receive the fluent string instance:

use Illuminate\Support\Str;
use Illuminate\Support\Stringable;

$string = Str::of('foo/bar')->whenIs('foo/*', function (Stringable $string) {
    return $string->append('/baz');

use Illuminate\Support\Str;
use Illuminate\Support\Stringable;

$string = Str::of('a0a2a2d2-0b87-4a18-83f2-2529882be2de')->whenIsUuid(function (Stringable $string) {
    return $string->substr(0, 8);
});

// 'a0a2a2d2'
