Php get information from xml data

Hi E's, I want use Goggle Weather Api in php.
For make a query to the API I use this URL: + the name of the city.
The result was:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<xml_api_reply version="1">
<weather module_id="0" tab_id="0" mobile_row="0" mobile_zipped="1" row="0" section="0">
<city data="Ayamonte, Andalusia"/>
<postal_code data="ayamonte"/>
<latitude_e6 data=""/>
<longitude_e6 data=""/>
<forecast_date data="2012-04-11"/>

You can use the SimpleXMLElement implementation to develop the functionality you need. See my sample code below:

	$low_data = array();
	$high_data = array();
	$xml_element = simplexml_load_file("");
	foreach($xml_element->weather->forecast_conditions as $condition){
		$low_data[(string)$condition->day_of_week['data']] = (string)$condition->low['data'];
		$high_data[(string)$condition->day_of_week['data']] = (string)$condition->high['data'];
	echo '<pre>';
	echo 'Low Data -> '; print_r($low_data);
	echo '<br><br>';
	echo 'High Data -> '; print_r($high_data);

Open in new window

The corresponding output from the above code will be as follows:

Low Data -> Array
    [Wed] => 68
    [Thu] => 70
    [Fri] => 68
    [Sat] => 70

High Data -> Array
    [Wed] => 84
    [Thu] => 84
    [Fri] => 81
    [Sat] => 79

Open in new window

As shown above the $low_data and $high_data variables are loaded with the required temperatures, indexed by their respective days.

Hope this helps...
