/**

|
|
* xml2array() will convert the given XML text to an array in the XML structure.
|
||
|
|
* Link: http://www.bin-co.com/php/scripts/xml2array/
|
||
|
|
* Arguments : $contents - The XML text
|
||
|
|
* $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value.
|
||
|
|
* $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance.
|
||
|
|
* Return: The parsed XML in an array form. Use print_r() to see the resulting array structure.
|
||
|
|
* Examples: $array = xml2array(file_get_contents('feed.xml'));
|
||
|
|
* $array = xml2array(file_get_contents('feed.xml', 1, 'attribute'));
