README

DataConverter类提供了一种简单方便的方式来将一种格式数据转换为另一种格式。无论是需要将CSV文件转换为JSON，还是将数组转换为YAML，此类都能满足您的需求。支持的格式包括CSV、JSON、XML、YAML、序列化PHP数据和PHP对象。

此类具有用户友好的界面，允许您轻松地将字符串或文件格式的数据转换为其他格式。此外，它还具有几个方法，允许您微调转换过程，例如指定XML转换的根元素和行元素。

凭借其全面的转换方法集，DataConverter类是任何PHP开发人员不可或缺的工具。无论您是在进行一个小型个人项目还是大型企业应用程序的开发，此类都可以帮助您简化数据转换需求。

    [name] => John Doe
    [email] => johndoe@example.com
    [phone] => 123456
)

序列化

$arrayData = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'phone' => '123456'
);
$serializedData = $dataConverter->serialize($arrayData, 'serialized');
echo $serializedData;

输出

a:3:{s:4:"name";s:8:"John Doe";s:5:"email";s:17:"johndoe@example.com";s:5:"phone";s:6:"123456";}

yamlToArray

$dataConverter = new DataConverter();
$yamlData = "name: John Doe
email: johndoe@example.com
phone: 123456";
$arrayData = $dataConverter->yamlToArray($yamlData);
print_r($arrayData);

输出

Array
(
    [name] => John Doe
    [email] => johndoe@example.com
    [phone] => 123456
)

arrayToYaml

$dataConverter = new DataConverter();
$arrayData = array(
    'name' => 'John Doe',
    'email' => 'johndoe@example.com',
    'phone' => '123456'
);
$yamlData = $dataConverter->arrayToYaml($arrayData);
echo $yamlData;

输出

name: John Doe
email: johndoe@example.com

csvToJson

$csv = "name,age,city\nJohn,30,New York\nJane,25,London";

$json = $dataConverter->csvToJson($csv);

// Output:
// '[{"name":"John","age":"30","city":"New York"},{"name":"Jane","age":"25","city":"London"}]'

jsonToCsv

$json = '[{"name":"John","age":"30","city":"New York"},{"name":"Jane","age":"25","city":"London"}]';

$csv = $dataConverter->jsonToCsv($json);

// Output:
// "name,age,city\nJohn,30,New York\nJane,25,London"

xmlToJson

$xml = '<data>
  <item>
    <name>John</name>
    <age>30</age>
    <city>New York</city>
  </item>
  <item>
    <name>Jane</name>
    <age>25</age>
    <city>London</city>
  </item>
</data>';

$json = $dataConverter->xmlToJson($xml);

// Output:
// '[{"name":"John","age":"30","city":"New York"},{"name":"Jane","age":"25","city":"London"}]'

jsonToXml

该方法接受两个参数：JSON字符串和可选的根元素名称（默认为"root"）。该方法返回结果XML字符串。

$json = '[{"name":"John","age":"30","city":"New York"},{"name":"Jane","age":"25","city":"London"}]';

$xml = $dataConverter->jsonToXml($json);

// Output:
// '<root>
//   <item>
//     <name>John</name>
//     <age>30</age>
//     <city>New York</city>
//   </item>
//   <item>
//     <name>Jane</name>
//     <age>25</age>
//     <city>London</city>
//   </item>
// </root>'

csvToXml

csvToXml方法将CSV字符串转换为XML字符串。

使用

该方法接受三个参数：CSV字符串、可选的分隔符

$dataConverter = new DataConverter();
$csv = <<< CSV
id,name,age
1,John Doe,32
2,Jane Doe,29
CSV;

$xml = $dataConverter->csvToXml($csv);
echo $xml;

这将生成以下XML输出

<?xml version="1.0"?>
<rows>
  <row>
    <id>1</id>
    <name>John Doe</name>
    <age>32</age>
  </row>
  <row>
    <id>2</id>
    <name>Jane Doe</name>
    <age>29</age>
  </row>
</rows>

您可以通过传递方法中的可选第二个和第三个参数来自定义根元素名称和行元素名称。例如

$xml = $dataConverter->csvToXml($csv, 'persons', 'person');
echo $xml;

这将生成以下XML输出

<?xml version="1.0"?>
<persons>
  <person>
    <id>1</id>
    <name>John Doe</name>
    <age>32</age>
  </person>
  <person>
    <id>2</id>
    <name>Jane Doe</name>
    <age>29</age>
  </person>
</persons>
