Php Expr Issue

[michael.davis]

Happy Monday Everyone! I hope you all had a great weekend!

 

I have a script that usually runs just fine, however, I ran into an issue today. We are having light rain, this my code below is not working due to the $match[1] field is not one word, it is two words. If I change the $city to a condition that is one word, then it works fine. I know it is something simple and hope someone can help me with it.

 

 

 

<?php

$data = file_get_contents('http://www.srh.noaa.gov/productview.php?pil=OHXRWROHX') or die("Can't open URL"); $city = 'Nashville';

$expr = "%$city*?\s+ ([a-z/]+)\s+ (n/a|\d+)\s+ (n/a|\d+)\s+ (n/a|\d+)\s+ ([a-z0-9]+)\s+ (n/a|[0-9.]+[a-z])%ix";

preg_match( $expr, $data, $match ); $site = $match[0]; $COND = $match[1]; $TEMP = $match[2]; $DEW = $match[3]; $HUMID = $match[4]; $WIND = $match[5]; $PRES = $match[6];

echo $site;
echo $COND;
echo $$TEMP;
echo $DEW;
echo $HUMID;
echo $WIND;
echo $PRES;
echo $data;
?>

 

The data below is what the script pulls in. The city of Gallatin works fine, but Nashville does not due to the two word in the $COND field.

I guess what I am trying to ask is what is the code format to look at not only one word but two words like Cloudy and LGT RAIN in one field like it is below: ([a-z/]+)\s+

 

 

$expr = "%$city*?\s+ ([a-z/]+)\s+ (n/a|\d+)\s+ (n/a|\d+)\s+ (n/a|\d+)\s+ ([a-z0-9]+)\s+ (n/a|[0-9.]+[a-z])%ix";

Change

 

([a-z/]+)

 

to

 

([a-z/]+(?:\s[a-z/]+)?)

 

this will allow an optional second word for the weather condition.
