PHP XML simple_load id

How do I parse "id" from the following event

<event id="100990">
   <title>myTitle</title>
</event>

I parse the title like this:开发者_如何学C

$xml->event[0]->title

Use the attributes method of SimpleXML

$id_attribute = (string)$xml->event[0]->attributes()->id;

You access attributes just like you would access elements of an associative array:

$xml_node['id'] // The value of the attribute `id` of the node `$xml_node`

The returned value is an object (with a __toString method), so you may want to typecast the returned value.

This is exactly what you need: http://www.php.net/manual/en/simplexmlelement.attributes.php
