Str 字符串#

Str类提供一个便捷的操作字符串的封装。

使用

• Str::camel

将给定字符串「蛇式」转化为 camelCase「驼峰式」

use MuCTS\String\Str;

$converted = Str::camel('foo_bar');
// fooBar

• Str::endsWith

函数判断指定的字符串是否以给定的值结尾

use MuCTS\String\Str;

$result = Str::endsWith('This is my name', 'name');
// true

• Str::kebab

将给定的「驼峰式」字符串转化为kebab-case「短横式」字符串

use MuCTS\String\Str;

$converted = Str::kebab('fooBar');
// foo-bar

• Str::snake

Str::snake 函数将给定的字符串转换为 snake_case「蛇式」

use MuCTS\String\Str;

$converted = Str::snake('fooBar');
// foo_bar

• Str::startsWith

Str::startsWith 函数判断给定的字符串的开头是否是指定值

use MuCTS\String\Str;

$result = Str::startsWith('This is my name', 'This');
// true

• Str::after

Str::after 函数返回在字符串中指定值之后的所有内容

use MuCTS\String\Str;

$slice = Str::after('This is my name', 'This is');
// ' my name'

• Str::before

Str::before 函数返回在字符串中指定值之前的所有内容

use MuCTS\String\Str;

$slice = Str::before('This is my name', 'my name');
// 'This is '

• Str::contains

Str::contains 函数判断给定的字符串是否包含给定的值（区分大小写）

use MuCTS\String\Str;

$contains = Str::contains('This is my name', 'my');

// true

• Str::finish

Str::finish 函数将给定的字符串以给定的值结尾返回（如果它尚未以给定值结尾）

use MuCTS\String\Str;

$adjusted = Str::finish('this/string', '/');
// this/string/
$adjusted = Str::finish('this/string/', '/');
// this/string/

• Str::is

Str::is 函数判断给定的字符串是否匹配给定的模式。星号 * 可以用来表示通配符

use MuCTS\String\Str;
$matches = Str::is('foo*', 'foobar');
// true
$matches = Str::is('baz*', 'foobar');
// false

• Str::limit

Str::limit 函数按给定的长度截断给定的字符串

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

你也可以传递第三个参数来改变将被追加到最后的字符串：

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

• Str::orderedUuid

Str::orderedUuid 方法高效生成一个可存储在索引数据库列中的「第一时间」 UUID

use MuCTS\String\Str;
return (string) Str::orderedUuid();

• Str::plural

Str::plural 函数将字符串转换为复数形式。该函数目前仅支持英文

use MuCTS\String\Str;
$plural = Str::plural('car');
// cars
$plural = Str::plural('child');
// children

你可以提供一个整数作为函数的第二个参数来检索字符串的单数或复数形式

use MuCTS\String\Str;
$plural = Str::plural('child', 2);
// children
$plural = Str::plural('child', 1);
// child

• Str::random

Str::random 函数生成一个指定长度的随机字符串。这个函数用 PHP 的 random_bytes 函数

use MuCTS\String\Str;
$random = Str::random(40);
