Question

How can I convert the following nested array into xml file? What will the XML file look like?

Array(
array('name'=>'Jone Smith','phone'=>'416-689-9865'),
array('name'=>'Jane    Ling','phone'=>'658-985-5222')
);

Answer 1

<?php
$your_array= array ('key1' => 'val1', 'key2' => 'val2', 'second_array' => array ('key3' => 'val3','key4' => 'val4'),);
$toXml = new SimpleXMLElement('<root/>');
array_walk_recursive($your_array, array ($toXml, 'addChild'));
print_r($toXml->asXML());

Other alternate is to use array_walk.
The array_walk_recursive() function runs each array element in a user-made function. The array’s keys and values are parameters in the function. The difference between this function and the array_walk() function is that with this function you can work with deeper arrays (an array inside an array)
