• Array2Xml - 类使用SimpleXMLElement类递归地将PHP关联数组转换为XML格式的字符串。
• ArrayIterator - 类将PHP数组转换为可迭代的对象（比SPL库中的相同方法内存消耗更少）。

Array2Xml使用场景

• 实例化转换器

 	<?php
        require_once realpath(__DIR__ . '/../vendor/autoload.php');
        use \ArrayUtils\Array2Xml;

• 为了添加属性 - 添加键'@attributes'，例如。

 		$a = [
 			'root' => [
 				'@attributes' => [
 					'attr1' => '1',
 				],
 			],
 		];
        $a2x = new Array2Xml($a);
        echo $a2x->conv();

Output:

<?xml version="1.0" encoding="UTF-8"?>
<root attr1="1"/>

• 为了添加节点文本内容 - 添加键'@content'，例如。

	<?php
		$a = [
		    'root' => [
		        'message' => [
		            '@content' => 'This is text content',
		        ],
		    ],
		];
        $a2x = new Array2Xml($a);
        echo $a2x->conv();

Output:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <message>This is text content</message>
</root>

• 短 '@content' 语法，例如。

 	<?php
		$a = [
		    'root' => [
		        'person' => [
		            'gender' => 'male',
		            'age' => '26',
		            'name' => 'Александр',
		        ],
		    ],
		];
        $a2x = new Array2Xml($a);
        echo $a2x->conv();

Output:

<?xml version="1.0" encoding="UTF-8"?>
<root>
  <person>
    <gender>male</gender>
    <age>26</age>
    <name>Александр</name>
  </person>
</root>

• 为了添加具有相同名称的标签，添加一个具有所需键名的枚举元素的数组，例如。

 	<?php
		$a = [
		    'root' => [
		        '@attributes' => [
		            'type' => 'test_type',
		            'id' => 'test_id',
		            'text' => 'русский текст'
		        ],
		        'main' => [
		            '@attributes' => [
		                'uid' => 'u201j3a0828ki3si0',
		                'src' => 'open',
		                'start' => '12423511247',
		                'stop' => '12423991978',
		                'adtp' => 'dbt',
		                'clid' => '100500',
		            ],
		            'attr' => [
		                [
		                    '@attributes' => [
		                        'code' => '1',
		                        'val' => '11',
		                    ],
		                ],
		                [
		                    '@attributes' => [
		                        'code' => '2',
		                        'val' => '12',
		                    ],
		                ],
		            ],
		            'history' => [
		                [
		                    '@attributes' => [
		                        'at1' => '1',
		                        'at2' => '2',
		                        'at3' => '3',
		                        'at4' => 'test',
		                    ],
		                ],
		            ],
		            'person' => [
		                'gender' => [
		                    	'@content' => 'male'
		                ],
		                'age' => [
		                    	'@content' => 26,
		                ],
		                'name' => [
		                    	'@content' => 'Александр'
		                ],
		            ],
		        ],
		    ],
		];
        $a2x = new Array2Xml($a);
        echo $a2x->conv();

Output:

<?xml version="1.0" encoding="UTF-8"?>
