question on if statement

[mjb982]

I'm writing a code that pulls current weather conditions from the NWS xml data. The problem I'm running into is I would like custom weather icons, not the default NWS ones.

 

I can accomplish this by using individual if statements for each weather description, ie:

 

if($current['weather']=="Partly Cloudy"){

$icon = "images/pcloudy.png";

}

 

But there are hundreds of them, ie "A Few clouds", "a few clouds and windy" etc... I was wondering if there was a way that I'm not familiar with do make an if statement where if "current['weather']" contiains the words "cloud" then I could display the correct image.

 

That would cut down the time it takes, and make things so much simpler. Something like

 

if($current['weather'] contains "cloud"){

$icon = "images/clouds.png"'

}

 

is it possible?

I would use str_pos() which will tell you if your string is part of the xml data

http://us.php.net/manual/en/function.strpos.php

 

<?php
$pos = str_pos('cloud', $current['weather']);
if($pos !== false){
     $icon = "images/clouds.png";
}
?>

 

Personally I dont like to use ==, !=, etc on strings but stick to the string comparision functions available (see strcmp() etc)

Hi

 

Another possibility would be to have an associative array of icons keyed on the possible descriptions.

 

All the best
