trouble with multiple KEY/VALUE pairs in URL
Date: Mon, 19 Dec 2005 13:11:38 -0800
Hello, i'm new to curl and have scanned the archives to an answer to
my issue but have found nothing that helped. Hopefully, this is a
simple issue....
I'm having trouble getting curl in php to return results from a web
service that takes multiple GET key/value pairs. Things work OK with
only one key value pair but it seems they get split up if more than
one and then the request doesn't work.
The URL i'm trying to get results from is: http://olla.berkeley.edu:
8080/dm/sal?lat=37&lng=-120&layers=srtm30 which should return a few
lines of XML.
The code i'm trying which just returns an empty page is:
<?php
$url="http://olla.berkeley.edu:8080/dm/sal?
lat=37&lng=-120&layers=srtm30";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_exec($ch);
curl_close($ch);
?>
I tried this using the command line curl, like:
curl -v http://olla.berkeley.edu:8080/dm/sal?
lat=37&lng=-120&layers=srtm30
which gives:
[jdeck@chignik berkeleymappertest]$ curl -v http://olla.berkeley.edu:
8080/dm/sal?lat=37&lng=-120&layers=srtm30

Interestingly, if i enclose the URL in quotes, things work as expected:
curl "http://olla.berkeley.edu:8080/dm/sal?
lat=37&lng=-120&layers=srtm30"
<?xml version="1.0" encoding="UTF-8"?>
<layers>
<srtm30 value = "95.0"/>
</layers>
I'd like to get this to work via PHP and tried putting extra quotes
in the URL string in PHP but that didn't work... Any clues??
thanks!
