| ## Convert XML to PHP Array | ||
| ## Convert XML to Array | ||
|
|
||
| This class can parse XML and return the document structure in an array. | ||
| It takes a string with a XML document and parses it using PHP SimpleXML or Expat extensions. | ||
| The class returns an nested array with the details of each XML document tag and data elements. | ||
| The class returns an nested array with the details of each XML document tag and data elements. | ||
|
|
||
| ## Examples | ||
|
|
||
| #### Simple XML without attributes | ||
|
|
||
| ```xml | ||
| <?xml version="1.0" encoding="utf-8"?> | ||
| <data> | ||
| <extra1>1111</extra1> | ||
| <extra2>2222</extra2> | ||
| <extra3>3333</extra3> | ||
| </data> | ||
| ``` | ||
|
|
||
| ```php | ||
| XmlToArray::xmlToArray($xml); | ||
|
|
||
| array( | ||
| 'data' => array( | ||
| 'extra1' => 1111, | ||
| 'extra2' => 2222, | ||
| 'extra3' => 3333, | ||
| ), | ||
| ) | ||
| ``` | ||
|
|
||
| #### More complex XML | ||
|
|
||
| ```xml | ||
| <?xml version="1.0" encoding="utf-8"?> | ||
| <data> | ||
| <id>1001</id> | ||
| <info att1="one" att2="two"></info> | ||
| <extra>1111</extra> | ||
| <extra>2222</extra> | ||
| <extra>3333</extra> | ||
| </data> | ||
| ``` | ||
|
|
||
| #### More informative array | ||
|
|
||
| ```php | ||
| XmlToArray::xmlToArray($xml); | ||
|
|
||
| array( | ||
| 'data' => array( | ||
| 'id' => 1001, | ||
| 'info' => null, | ||
| '@info' => array( | ||
| 'att1' => 'one', | ||
| 'att2' => 'two', | ||
| ), | ||
| 'extra' => array( | ||
| 0 => 1111, | ||
| 1 => 2222, | ||
| 2 => 3333, | ||
| ), | ||
| ), | ||
| ) | ||
| ``` | ||
|
|
||
| #### Attributes is priority | ||
|
|
||
| ```php | ||
| XmlToArray::xmlToArray($xml, true, false); | ||
|
|
||
| array( | ||
| 'data' => array( | ||
| 'id' => array( | ||
| 'value' => 1001, | ||
| ), | ||
| 'info' => array( | ||
| '@attributes' => array( | ||
| 'att1' => 'one', | ||
| 'att2' => 'two', | ||
| ), | ||
| ), | ||
| 'extra' => array( | ||
| 0 => array( | ||
| 'value' => 1111, | ||
| ), | ||
| 1 => array( | ||
| 'value' => 2222, | ||
| ), | ||
| 2 => array( | ||
| 'value' => 3333, | ||
| ), | ||
| ), | ||
| ), | ||
| ) | ||
| ``` | ||
|
|
||
| #### Attributes can be omitted | ||
|
|
||
| ```php | ||
| XmlToArray::xmlToArray($xml, false, true); | ||
|
|
||
| array( | ||
| 'data' => array( | ||
| 'id' => 1001, | ||
| 'info' => null, | ||
| 'extra' => array( | ||
| 0 => 1111, | ||
| 1 => 2222, | ||
| 2 => 3333, | ||
| ), | ||
| ), | ||
| ) | ||
| ``` | ||
|
|
||
| #### Attributes will be omitted and tags will fulfill role of attributes | ||
|
|
||
| ```php | ||
| XmlToArray::xmlToArray($xml, false, false); | ||
|
|
||
| array( | ||
| 'data' => array( | ||
| 'id' => array( | ||
| 'value' => 1001, | ||
| ), | ||
| 'info' => null, | ||
| 'extra' => array( | ||
| 0 => array( | ||
| 'value' => 1111, | ||
| ), | ||
| 1 => array( | ||
| 'value' => 2222, | ||
| ), | ||
| 2 => array( | ||
| 'value' => 3333, | ||
| ), | ||
| ), | ||
| ), | ||
| ) | ||
| ``` | ||
