Good evening,
I am retrieving a JSON file and trying to read a variable at the very end of the file.
$eedomus_api_user = 'xyz';
$eedomus_api_secret = 'zzz';
$periph_id = 'yyy';
$url = "http://19X.XXX.0.XX/api/get?";
$url .= "api_user=$eedomus_api_user";
$url .= "&api_secret=$eedomus_api_secret";
$url .= "&action=periph.value";
$url .= "&periph_id=$periph_id";
$result = file_get_contents($url);
$phpObj = json_decode($result, true);
The file I'm getting is the following :
{ "success": 1, "body":{"last_value": 100} }
I'm interested in getting the '100' corresponding to the last_value field.
Using the function strpos, I'm intending to look for the position of the first '}' and retrieve the characters until the previous space. Is there an easier way to achieve this ?
Thanks for your help.

OK... I am using PHP 5 (be gentle, still learning PHP). CURL is enabled. Attempting to load XML or JSON output from an API to an object and nothing happens. When I manually execute the URL in question, I get what I am expecting.
Here is my code:
class XmlToJson {
public function Parse ($url) {
$fileContents = file_get_contents($url);
$fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);
$fileContents = trim(str_replace('"', "'", $fileContents));
$simpleXml = simplexml_load_string($fileContents);
$json = json_encode($simpleXml);
return $json;
}
}
$_MySQLServer = "localhost";
$_MySQLServerUserName = "";
$_MySQLServerPassword = "";
$_MySQLDatabaseName = "";
$_SSActiveWear_UserID = "*****";
$_SSActiveWear_APIKey = "*****";
$_SSActiveWear_APIBaseURL = "https://*****/v2";
$_CategoryURL = "/categories/";
$_StylesURL = "/styles/";
$_ProductsURL = "/products/";
$_SpecsURL = "/specs/";
$_SSActiveWear_MediaType = "xml";
//$_conn = mysqli_connect($_MySQLServer, $_MySQLServerUserName, $_MySQLServerPassword, $_MySQLDatabaseName);
//Insert or Update Categories
$_URL = $_SSActiveWear_APIBaseURL . $_CategoryURL;
$_URL = $_URL . "?mediatype=$_SSActiveWear_MediaType&UserName=$_SSActiveWear_UserID&Password=$_SSActiveWear_APIKey";
$OBJ = simplexml_load_string($_URL);
print_r($OBJ);
What am I doing wrong?
Edit 1
Added the following code:
$xml = simplexml_load_file($_URL) or die("Error: Cannot create object");
print_r($xml);
and it dies. Does that mean that there is something wrong with the code?
Try this :
$OBJ = simplexml_load_string(file_get_contents($_URL));
If you want to know why your code is not working, you are trying to load XML from URL but "simplexml_load_string" loads XML from string.
I FINALLY figured it out... More to the point I finally found a site on Google that helped. It is the first answer in fsockopen with http authentication problem.
So here is the code that works:
file_get_contents("https://$_SSActiveWear_UserID:$_SSActiveWear_APIKey#$_SSActiveWear_APIBaseURL$_CategoryURL/?mediatype=$_SSActiveWear_MediaType");
mediatype can be either json or xml
So despite hours of fiddling I cannot understand why my JSON query only returns a result for the last line in the CSV/TXT files I am trying to parse.
Here is the code:
//Enter API Key Here
$api_key = 'AIzaSyB9Dq3w1HCxkS5qyELI_pZuTmdK8itOBHo';
$origin = 'RG12 1AA';
$output_type = 'json'; //xml or json
$csv_location = 'http://www.naturedock.co.uk/postcodes.csv';
//Do not edit
$base_url = 'https://maps.googleapis.com/maps/api/directions/';
$origin_url = '?origin=';
$destination_url = '&destination=';
$end_url = '&sensor=false&key=';
$page = join("",file("$csv_location"));
$kw = explode("\n", $page);
for($i=0;$i<count($kw);$i++){
$destination = $kw[$i];
echo $destination;
$raw_url = $base_url . $output_type . $origin_url . $origin . $destination_url . $destination . $end_url . $api_key;
$request_url = str_replace(' ', '', $raw_url);
$getJson = file_get_contents($request_url);
$routes = json_decode($getJson);
$result = $routes->routes[0]->legs[0]->distance->value;
echo $result . '<br>';
}
The result I get looks like this:
Distance by Post Code Generator v0.1 by Phil Hughes
RG12 0GA
RG12 0GB
RG12 0GC
RG12 0GD4066
Where the '4066' is the correct variable for RG12 0GD postcode but none of the others return results as you can see.
Please help.
Your
join("",file("$csv_location"));
concatenated all lines feom the file to a single line without separator. The following explode() sees no newlines any more. So you are working on one line only. count($kw) always evaluates to 1 and your loop runs only one time.
I would like to be able to extract a title and description from Wikipedia using json. So... wikipedia isn't my problem, I'm new to json and would like to know how to use it. Now I know there are hundreds of tutorials, but I've been working for hours and it just doesn't display anything, heres my code:
<?php
$url="http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=google&format=json&explaintext&redirects&inprop=url";
$json = file_get_contents($url);
$data = json_decode($json, TRUE);
$pageid = $data->query->pageids;
echo $data->query->pages->$pageid->title;
?>
Just so it easier to click:
http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=google&format=json&explaintext&redirects&inprop=url&indexpageids
I know I've probably just done a tiny thing wrong, but its really bugging me, and the code... I'm used to using xml, and I have pretty much just made the switch, so can you explain it a bit for me and for future visitors, because I'm very confused... Anything you need that I haven't said, just comment it, im sure I can get it, and thanks, in advance!
$pageid was returning an array with one element. If you only want to get the fist one, you should do this:
$pageid = $data->query->pageids[0];
You were probably getting this warning:
Array to string conversion
Full code:
$url = 'http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=google&format=json&explaintext&redirects&inprop=url&indexpageids';
$json = file_get_contents($url);
$data = json_decode($json);
$pageid = $data->query->pageids[0];
echo $data->query->pages->$pageid->title;
I'd do it like this. It supports there being multiple pages in the same call.
$url = "http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=google&format=json&explaintext&redirects&inprop=url";
$json = file_get_contents($url);
$data = json_decode($json, TRUE);
$titles = array();
foreach ($data['query']['pages'] as $page) {
$titles[] = $page['title'];
}
var_dump($titles);
/* var_dump returns
array(1) {
[0]=>
string(6) "Google"
}
*/
Try this it will help you 💯%
This code is to extract title and description with the help of Wikipedia api from Wikipedia
<?php
$url = 'http://en.wikipedia.org/w/api.php?action=query&prop=extracts|info&exintro&titles=google&format=json&explaintext&redirects&inprop=url&indexpageids';
$json = file_get_contents($url);
$data = json_decode($json);
$pageid = $data->query->pageids[0];
$title = $data->query->pages->$pageid->title;
echo "<b>Title:</b> ".$title."<br>";
$string=$data->query->pages->$pageid->extract;
// to short the length of the string
$description = mb_strimwidth($string, 0, 322, '...');
// if you don't want to trim the text use this
/*
echo "<b>Description:</b> ".$string;
*/
echo "<b>Description:</b> ".$description;

I have a small problem with my tweets script. But for some reason, I don't know what the error could be. This is the error it gives me:
$url = "http://www.twitter.com/statuses/user_timeline/{$username}.xml?count={$number}";
$tweets = file_get_contents($url);
$feed = new SimpleXMLElement($tweets);
function time_stamp($date){
if (empty($date)){
return "No date provided";
}
and on the index.php page, it'll show this code:
<?php
$username = "user";//your twitter username
$number = 3;//number of tweets
include ("{$dir}/php/tweets.php");
?>
Do you guys know what it is that I'm doing wrong?
You don't need file_get_contents()
Try:
$url = "http://www.twitter.com/statuses/user_timeline/{$username}.xml?count={$number}";
$feed = simplexml_load_file($url);
Also, twitter made some changes not too long ago so your URL needs to look like this:
$url = "http://api.twitter.com/1/statuses/user_timeline/{$username}.xml?count={$number}";
Check this discussion.
You can use JSON easy and faster than XML
And to get content you can use
Curl => Faster
or
File_get_contents
Url
https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name={screenname}&count={count}
like this
<?php
$url = 'https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=abdullaheid&count=3'
$x = file_get_contents( $url ) ; // Using file get contents
$object = json_decode( $x ) ;
$array = (array) $object ;
print_r( $array ) ;
?>
I am trying to read a weather feed from Yahoo to my site.
Using the code below I was able to print the xml.
What I really want to achieve now is to put the temperature and image in two different variables
$zipCode = "44418";
$url = "http://weather.yahooapis.com/forecastrss";
$zip = "?w=$zipCode";
$fullUrl = $url . $zip.'&u=c';
$curlObject = curl_init();
curl_setopt($curlObject,CURLOPT_URL,$fullUrl);
curl_setopt($curlObject,CURLOPT_HEADER,false);
curl_setopt($curlObject,CURLOPT_RETURNTRANSFER,true);
$returnYahooWeather = curl_exec($curlObject);
curl_close($curlObject);
print "yahooWeather". $returnYahooWeather;
//$temperature
//$image
You should go ahead and use simplexml or DOM to parse the XML and then you can iterate over the results. With SimpleXML this looks like this:
$zipCode = "44418";
$url = "http://weather.yahooapis.com/forecastrss";
$zip = "?w=$zipCode";
$fullUrl = $url . $zip.'&u=c';
$curlObject = curl_init();
curl_setopt($curlObject,CURLOPT_URL,$fullUrl);
curl_setopt($curlObject,CURLOPT_HEADER,false);
curl_setopt($curlObject,CURLOPT_RETURNTRANSFER,true);
$returnYahooWeather = curl_exec($curlObject);
curl_close($curlObject);
//print "here". $returnYahooWeather;
$xmlobj=simplexml_load_string($returnYahooWeather);
$res = $xmlobj->xpath("//yweather:condition");
$tmp = false;
while(list( , $node) = each($res)) {
$tmp = $node;
}
$attribs = $tmp->attributes();
print "Temperature [".$attribs['temp']."]";
I find it easiest to SimpleXML with PHP.
$xml = simplexml_load_string($returnYahooWeather);
echo $xml->Path->To->Temperature;
It's easy enough, and you can use XPath with SimpleXML :). There are other ways of parsing XML too, as previously mentioned DOMDocument is one of them.
