Question

I’m trying to build a PHP if expression.

In English, here’s the conditions for the IF to be true:

Visbility < 5000m

OR

BKN/OVC < 1500ft

Now, the variables I have to play with are:

for Visibility: $visibility and for the BKN/OVC: it’s a bit more complex.

This data is given in

$xml->data->METAR[0]->sky_condition

The data itself is pulled from XML file with the relevant information looking like this:

<sky_condition sky_cover="BKN" cloud_base_ft_agl="600"/>
<sky_condition sky_cover="SCT" cloud_base_ft_agl="1100"/>

Any ideas on how I could sort through the sky_condition->sky_cover for the relevant information and feed it through to the IF?

Thanks.

Answer 1

You could access the attributes of the XML with the array syntax instead of the arrow operator.

if((string)$xml->data->METAR[0]->sky_condition[0]['sky_cover']==='???') {

}

Was this your question?
