Issue
I have this php code using cURL to parse an xml feed from Indeed.com. I'm passing server information such as REMOTE_ADDR and HTTP_USER_AGENT into the parameters of the url but they are not being passed.
Check this part of the code below. '.geoCheckIP($_SERVER['REMOTE_ADDR']).'
This is the correct way to do it. Just not sure if it is the correct way to do it when it is part of an array in CURLOPT_URL =>
What is the proper way to pass these server snippets into the url parameters when using an array in cURL like in the below function in CURLOPT_URL =>?
The below php code is the entire code on my page so you can get a better idea of what is going on.
I'm trying to detect the users city, state when they arrive at my site to display job listings in their local area. The php code works and I can echo the city state on the web page, but it is just not passing that same info to the function curl_request() in the array. Please help.
<?php
// Convert IP into city state country (Geo Location function)
function geoCheckIP($ip){
if(!filter_var($ip, FILTER_VALIDATE_IP))
{
throw new InvalidArgumentException("IP is not valid");
}
$response=@file_get_contents('http://www.netip.de/search?query='.$ip);
if (empty($response))
{
throw new InvalidArgumentException("Error contacting Geo-IP-Server");
}
$patterns=array();
$patterns["domain"] = '#Domain: (.*?) #i';
$patterns["country"] = '#Country: (.*?) #i';
$patterns["state"] = '#State/Region: (.*?)<br#i';
$patterns["town"] = '#City: (.*?)<br#i';
$ipInfo=array();
foreach ($patterns as $key => $pattern)
{
$ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : 'not found';
}
/*I've included the substr function for Country to exclude the abbreviation (UK, US, etc..)
To use the country abbreviation, simply modify the substr statement to:
substr($ipInfo["country"], 0, 3)
*/
$ipdata = $ipInfo["town"]. ", ".$ipInfo["state"]/*.", ".substr($ipInfo["country"], 4)*/;
return $ipdata;
}
// Indeed php function
function curl_request(){
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch?publisher=&q=computer+repair&l='.geoCheckIP($_SERVER['REMOTE_ADDR']).'&sort=&radius=25&st=&jt=&start=&limit=&fromage=&highlight=1&filter=1&latlong=0&co=us&chnl=computer+help+wanted&userip='.$_SERVER['REMOTE_ADDR'].'&useragent='.$_SERVER['HTTP_USER_AGENT'].'&v=2',
));
$resp = curl_exec($curl);
curl_close($curl);
return $resp;
}
function xmlToArray($input, $callback = null, $recurse = false) {
$data = ((!$recurse) && is_string($input))? simplexml_load_string($input, 'SimpleXMLElement', LIBXML_NOCDATA): $input;
if ($data instanceof SimpleXMLElement) $data = (array) $data;
if (is_array($data)) foreach ($data as &$item) $item = xmlToArray($item, $callback, true);
return (!is_array($data) && is_callable($callback))? call_user_func($callback, $data): $data;
}
?>
FUNCTION CALL
This is how the function is called in the body
<ol>
<?php
for($i=0;$i<10;$i++){ // using for loop to show number of jobs
$resp=curl_request($i);
$arrXml = xmlToArray($resp);
$results=$arrXml['results'];
?>
<li>
<p><strong>Job :</strong> <a href="<?php echo $results['result'][$i]['url']; ?>" target="_blank"><?php echo $results['result'][$i]['jobtitle']; ?></a></p>
<p><strong>Company:</strong> <?php echo $results['result'][$i]['company']; ?></p>
<p><strong>Location:</strong> <?php echo $results['result'][$i]['formattedLocationFull']; ?></p>
<p><strong>Date Posted :</strong> <?php echo $results['result'][$i]['formattedRelativeTime'];?> on <?php echo $results['result'][$i]['date'];?></p>
<p><strong>Description :</strong> <?php echo $results['result'][$i]['snippet']; ?></p>
</li>
<?php } ?>
</ol>
What works
This code above works only if I remove the variables from the CURLOPT_URL
This works
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch?publisher=&q=computer+repair&l=city,state&sort=&radius=25&st=&jt=&start=&limit=&fromage=&highlight=1&filter=1&latlong=0&co=us&chnl=computer+help+wanted&userip=111.111.111.111&useragent=mozila&v=2',
This does not work
CURLOPT_URL => 'http://api.indeed.com/ads/apisearch?publisher=&q=computer+repair&l='.geoCheckIP($_SERVER['REMOTE_ADDR']).'&sort=&radius=25&st=&jt=&start=&limit=&fromage=&highlight=1&filter=1&latlong=0&co=us&chnl=computer+help+wanted&userip='.$_SERVER['REMOTE_ADDR'].'&useragent='.$_SERVER['HTTP_USER_AGENT'].'&v=2',
Solution
Using cURL is not needed for this and was loading very slow. Here is a very simple way to get the results of the xml document in pure php with the geoCheckIP function fully working with it.
<?php
// Convert IP into city state country (Geo Location function)
function geoCheckIP($ip){
if(!filter_var($ip, FILTER_VALIDATE_IP))
{
throw new InvalidArgumentException('IP is not valid');
}
$response=@file_get_contents('http://www.netip.de/search?query='.$ip);
if (empty($response))
{
throw new InvalidArgumentException('Error contacting Geo-IP-Server');
}
$patterns=array();
$patterns["domain"] = '#Domain: (.*?) #i';
$patterns["country"] = '#Country: (.*?) #i';
$patterns["state"] = '#State/Region: (.*?)<br#i';
$patterns["town"] = '#City: (.*?)<br#i';
$ipInfo=array();
foreach ($patterns as $key => $pattern)
{
$ipInfo[$key] = preg_match($pattern,$response,$value) && !empty($value[1]) ? $value[1] : 'not found';
}
/*I've included the substr function for Country to exclude the abbreviation (UK, US, etc..)
To use the country abbreviation, simply modify the substr statement to:
substr($ipInfo["country"], 0, 3)
*/
$ipdata = $ipInfo["town"]. ", ".$ipInfo["state"]/*.", ".substr($ipInfo["country"], 4)*/;
return $ipdata;
}
// Indeed.com API URL parameters
$url = 'http://api.indeed.com/ads/apisearch'.'?';
$publisher = 'YOUR PUB NUMBER GOES HERE';
$q = 'title:(java or java+programmer or java+programming)';
$l = geoCheckIP($_SERVER['REMOTE_ADDR']);
$sort = 'date';
$radius = '20';
$st = '';
$jt = '';
$start = '0';
$limit = '25';
$fromage = '';
$highlight = '0';
$filter = '1';
$latlong = '0';
$co = 'us';
$chnl = 'YOUR CHANNEL NAME';
$userip = $_SERVER['REMOTE_ADDR'];
$useragent = isset($_SERVER['HTTP_USER_AGENT']) ? ($_SERVER['HTTP_USER_AGENT']) : 'unknown';
$v = '2';
Then the rest of the code you see below will go below the <body> tag of your page where you want the output to show up at.

$xml = simplexml_load_file($url."publisher=".$publisher."&q=".$q."&l=".$l."&sort=".$sort."&radius=".$radius."&st=".$st."&jt=".$jt."&start=".$start."&limit=".$limit."&fromage=".$fromage."&highlight=".$highlight."&filter=".$filter."&latlong=".$latlong."&co=".$co."&chnl=".$chnl."&userip=".$userip."&useragent=".$useragent."&v=".$v);
foreach($xml->results->result as $result) { ?>
