Hi E's, I want use Goggle Weather Api in php.
For make a query to the API I use this URL: http://www.google.com/ig/api?weather= + 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.

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

<?php
	$low_data = array();
	$high_data = array();
	
	$xml_element = simplexml_load_file("http://www.google.com/ig/api?weather=miami");
	
	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...
