I have another xml doc 2 which i have changed only one value - address="0800000" in the first which is address="0900000" in the second.When i compare the two arrays using
include "xml2array.php";
$contents = file_get_contents('sms.xml');//Or however you what it
$result = xml2array($contents);
//print_r($result);
$contents_ = file_get_contents('smsz.xml');//Or however you what it
$result_ = xml2array($contents_);
//print_r($result_);
$result_diff = array_diff($result, $result_);
print_r($result_diff);
i get which is not what i was expecting.
Array ( )
I was expecting something like
Array
(
[1] => 0900000
)
You have a multi-dimsensional array and array_diff only support one dimension.
From the manual about array_diff:
This function only checks one dimension of a n-dimensional array. Of course you can check deeper dimensions by using array_diff($array1[0], $array2[0]);.
