How to form a list of XML elements with the same attributes based on a php array?

Question

PHP

There is a numeric array of telephone numbers, it must be converted to an associative array,
so that all elements of the array have the same keys! How can I do that?

// в таком виде массив приходит на PHP скрипт в результате Ajax запроса
$NrList = array(
  0=>'9250999998',
  1=>'9250999911'
);

So you need to form a list of XML elements for the SOAP message.

<NrList>
  <Nr>9200925068</Nr>
  <Nr>9200925069</Nr>
 </NrList>

Answer 1

in any way, in an array keys can only be unique.

$NrList = array(
  'Nr'=>'9250999998',
  'Nr'=>'9250999911'
);

This is

array(1) {
  'Nr' =>
  string(10) "9250999911"
}

Answer 2

key cannot be the same

$NrList = array(
  'Nr'=>array('9250999998',
 '9250999911')
);
