Edit SimpleXML node in a foreach loop

Question

I'm trying to edit a node value while in a loop. I can edit nodes with unique names just fine.

 $gdNodes->orgName = 'test';

But when I'm in a loop, the value is not saved when I output my XML.

foreach($gdNodes->phoneNumber as $phone) { $phone = '1234567'; }

Both are SimpleXMLElement class objects. I don't understand why it's not saving. How is it done?

It won't save because $phone is a scalar copy of the original value.

You should be able to reach your goal like this:

foreach($gdNodes->phoneNumber as $key => $phone) { $gdNodes->phoneNumber[$key] = '1234567'; }

$key outputs 'phoneNumber'. Looks like I'll have to do it with a for loop. Thank you.
