函数和同名类的描述

isEmptyArrayFilter

[] === array_filter($array)

isNotEmptyArrayFilter

[] !== array_filter($array)

isEmptyArray [IsEmptyArray]

[] === $value

isNotEmptyArray [IsNotEmptyArray]

true === is_array($value) && [] !== $value

isNotEmptyString [IsNotEmptyString]

true === is_string($value) && '' !== $value

isNotNull [IsNotNull]

null !== $value

isNull [IsNull]

null === $value

isNullOrEmptyString [IsNullOrEmptyString]

null === $value || '' === $value

isNullOrZeroNumber [IsNullOrZeroNumber]

null === $value || 0 === $value || 0.0 === $value

其他

• strStartsWith 检查字符串是否以指定的字符（子字符串）开头
• objectToArray 返回对象数据，不使用反射

    class A
    {
    	private $a = 1;
    	protected $b = 2;
    	public $c = 3;
    }

    var_dump(objectToArray(new A));

结果

array:3 [▼
  "a" => 1
  "b" => 2
  "c" => 3
]

• all 如果数组中的每个元素都满足 $callback 函数中的条件，则返回 TRUE

$isBelowThreshold = function ($value) {
    return $value < 40;
};

$items = [1, 30, 39, 29, 10, 13];

var_dump(all($items, $isBelowThreshold));

结果

true

• MethodHelper::isSetter - 如果方法名称以 set[A-Z] 开头，则为 true
• MethodHelper::isAdder - 如果方法名称以 add[A-Z] 开头，则为 true
• MethodHelper::isGetter - 如果方法名称以 get[A-Z] 开头，则为 true
• MethodHelper::isLogic - 如果方法名称以 is[A-Z] 或 getIs[A-Z] 开头，则为 true

使用 array_filter 的示例

use Sharoff45\Library\Support\IsNotEmptyArray;
use Sharoff45\Library\Support\IsNotEmptyString;
use Sharoff45\Library\Support\IsNotNull;
use Sharoff45\Library\Support\IsNull;
use Sharoff45\Library\Support\IsNullOrEmptyString;
use Sharoff45\Library\Support\IsEmptyArray;

// ...
$result = array_filter($list, new IsNotEmptyArray());

//...
$result = array_filter($list, new IsNotEmptyString());

// ...
$result = array_filter($list, new IsNotNull());

//...
$result = array_filter($list, new IsNull());

// ...
$result = array_filter($list, new IsNullOrEmptyString());

// ...
$result = array_filter($list, new IsEmptyArray());

条件中使用示例

use function Sharoff45\Library\Support\isEmptyArray;
use function Sharoff45\Library\Support\isNotEmptyArray;
use function Sharoff45\Library\Support\isNotEmptyString;
use function Sharoff45\Library\Support\isNotNull;
use function Sharoff45\Library\Support\isNull;
use function Sharoff45\Library\Support\isNullOrEmptyString;
use function Sharoff45\Library\Support\isEmptyArrayFilter;
use function Sharoff45\Library\Support\isNotEmptyArrayFilter;

if (isEmptyArray($value)) {}

if (isNotEmptyArray($value)) {}

if (isNotEmptyString($value)) {}

if (isNotNull($value)) {}

if (isNull($value)) {}

if (isNullOrEmptyString($value)) {}

if (isEmptyArrayFilter($array)) {}

if (isNotEmptyArrayFilter($array)) {}

处理 JSON 的函数

抛出异常

• Json::encode - 返回数据的 JSON 表示形式

echo Json::encode(['a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5]);

结果

{"a":1,"b":2,"c":3,"d":4,"e":5}

解码

• Json::decodeAsArray - 将 JSON 对象返回为关联数组（array）

var_dump(Json::decodeAsArray('{"a":1,"b":2,"c":3,"d":4,"e":5}'));

结果

array(5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

• Json::decodeAsObject - 将 JSON 对象返回为对象（object）

var_dump(Json::decodeAsObject('{"a":1,"b":2,"c":3,"d":4,"e":5}'));

结果

object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

В случае ошибки возвращается  `JsonException`

生成 Uuid

UuidGenerator::getUuid 方法用于获取 uuid，无论输入是 ID 还是已经准备好的 uuid
