PHP Tutorials Examples PHP Recursive Array To XML With DOM

This class provides a method to recursively create XML from a PHP array. The functionality is provided by extending the built in Document Object Model (DOM) class. By extending the DOM class, all the functions within are available locally to the array2xml class. The main engine in this class is the createNode method, which is a recursive function that adds the child nodes to the parent root directory.

integration interspire email marketer step 1

http://idn.interspire.com/categories/Email-Marketer/

that link is not very complete. i spent hours just to make the sample working. it is not very tricky though. here was my problem. i was trying to integrate IEM with joomla. i followed the sample, and the sample needs the usertoken. i tried to look up everywhere on the installation, but i couldnt find it. so i looked up on the database directly. yes it was there. but it more than 64 character. i tried to put it on the sample code, and ofcourse it wasnt going to work anyway.

i relooked up on the admin panel of IEM. and LOL i found a check box “enable this user to use xml API”. click save. and then it gives you the correct API token. copy paste that token, and the sample is working.

the PHP code is still the same as the sample on the link. just copy paste that.
