Hi I'm trying get a json from fixer.io and then for each rates echo it but cant get it to work.
the code are
<?php
function usd(){
echo 'HEJ test';
$fixer_access_key = my_access_key;
$url= 'https://data.fixer.io/api/latest?access_key=' . $fixer_access_key;
echo $url;
$json = file_get_contents($url);
$data = json_decode($json);
echo $url . "<br>";
echo 'printing json foreach <br>';
foreach($data as $obj){
echo '...';
$prefix = $obj;
echo $prefix;
echo '<br>';}
echo 'done printing json foreach';
}
usd(); ?>
and the result are:
https://data.fixer.io/api/latest?access_key=my_fixer_key
printing json foreach
done printing json foreach
instead of
$data = json_decode($json);
use
$data = json_decode($json, true);
This should allow foreacha to works - however you will only see first level of json object keys (not nested ones). The second parameter of json_decode change result from object to array.
You will also need to change foreach - to following: foreach($data as $key => $obj) and inside it echo $obj to echo $key;.
Here is simplified working example.
ALTERNATIVE SOLUTION
If working foreach is not your goal but rather pretty printed json, then instead use following code:
$json_string = json_encode($data, JSON_PRETTY_PRINT);
echo $json_string;
I have a URL that returns JSON data and is constantly being updated. I'm trying to get the contents of this data to show up on my site. Here is JSON file (url)
I only need the contents from the 'images' (pretty far down there) array ... when I try and use just simple php code:
$json_data = file_get_contents($url);
$json = json_decode($str, true);
$result = array();
foreach($json['designs']['images'] as $image); {
$result[] = $image['url'];
}
echo $result;
I just keep returning 'Array' on the browser. If I replace echo with print_r I get this: Array ( [0] => SWZ51F ) which is correct, but i would like it to display in HTML format.
After the loop, $result is an array of all image URLs. You can loop through it to output the html. A basic approach would be :
foreach ($result as $url) {
echo '<img src="' . $url . '"/><br/>';
}
Or use a single loop:
foreach($json['designs']['images'] as $image); {
echo '<img src="' . $image['url'] . '"/><br/>';
}
Try this:
This is for ALL IMAGES URL:
$result = array();
foreach($json['designs']['images'] as $image){
$result[] = $image['url'];
}
var_dump($result);
This is for single IMAGE URL:
$result=$json['designs']['images'][0]['url'];
echo $result;
How can I parse this JSON, which is supposed to display the items a user has in their Steam inventory.
I have tried this:
$data = file_get_contents('http://steamcommunity.com/id/Mitch8910/inventory/json/440/2/');
$json = json_decode($data);
echo $data;
It returns the same as just visiting the link. I can't get anything like this to work either:
$id = $json->type;
echo $type;
This is how to get type
$data = file_get_contents('http://steamcommunity.com/id/Mitch8910/inventory/json/440/2/');
$json = json_decode($data);
foreach ($json->rgDescriptions as $mydata)
{
echo $mydata->type;
}
$data = file_get_contents('http://steamcommunity.com/id/Mitch8910/inventory/json/440/2/');
$json = json_decode($data);
echo $data;
you are echoing $data that is your input (so you see the same as opening the link directly). To see if the json_decode is working fine you should print $json.
So instead of
echo $data;
use
echo '<pre>'
print_r($json);
echo '</pre>';
$data = file_get_contents('http://steamcommunity.com/id/Mitch8910/inventory/json/440/2/');
$json = json_decode($data);
Now $json has 2 objects.
you can access like.
$json->rgInventory;
$json->success;
if you want to fetch all data from $json->rgInventory;
foreach($json->rgInventory as $e){
//var_dump($e);
echo $e->id;
echo $e->classid;
echo $e->instanceid;
}
etc.
I am using the below code to fetch the $movie->id from the response XML
<?php
$movie_name='Dabangg 2';
$url ='http://api.themoviedb.org/2.1/Movie.search/en/xml/accd3ddbbae37c0315fb5c8e19b815a5/%22Dabangg%202%22';
$xml = simplexml_load_file($url);
$movies = $xml->movies->movie;
foreach ($movies as $movie){
$arrMovie_id = $movie->id;
}
?>
the response xml structure is
How to fetch image URL with thumb size?
See the below an easy way to get only specific images.
$xml = simplexml_load_file($url);
$images = $xml->xpath("//image");
//echo "<pre>";print_r($images);die;
foreach ($images as $image){
if($image['size'] == "thumb"){
echo "URL:".$image['url']."<br/>";
echo "SIZE:".$image['size']."<br/>";
echo "<hr/>";
}
}
Use the attributes() method of SimpleXmlElement.
Example:
$imageAttributes = $movie->images[0]->attributes();
$size = $imageAttributes['size'];
See the documentation at: http://www.php.net/manual/en/simplexmlelement.attributes.php
EDIT: select only URL attributes with size = "thumb" and type = "poster":
$urls = $xml->xpath("//image[#size='thumb' and #type='poster']/#url");
if you expect only 1 url, do:
$url = (string)$xml->xpath("//image[#size='thumb' and #type='poster']/#url")[0];
echo $url;

use json_decode function in PHP to get assosiative array.
<?php
$myJson = '{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}';
$myArray = json_decode($myJson,true);
$myInnerArray = $myArray['elements'];
$styles = array();
foreach($myInnerArray as $element)
$styles[] = $element['styles'];
print_r($styles);

PHP has great abilities to handle json.
Let's assume the JSON string you've posted above is stored in a PHP variable $myJSON.
So we can easily store an associative array of these values into $myJSONArray like so:
$myJSONArray = json_decode( $myJSON, true );
So, now we just loop through:
foreach( $myJSONArray['elements'] as $arr => $key )
echo( "A PID: " . $key['pid'] . "\n" );
See it in action on Codepad.
$json = json_decode('{"general":{"note":{"display":false}},"elements":{"the-1":{"index":1,"src":"shirt1.png","pid":"pid-3563130","angle":0,"styles":"background:transparent;top:51.80000305175781px;left:122px;width:80px;height:80px;","background":"transparent","pos":{"top":51.80000305175781,"left":122},"size":{"width":80,"height":80},"details":{"other":""}},"the-2":{"index":2,"src":"shirt2.png","pid":"pid-132002","angle":0,"styles":"background:transparent;top:44.80000305175781px;left:155px;width:80px;height:80px;","background":"transparent","pos":{"top":44.80000305175781,"left":155},"size":{"width":80,"height":80},"details":{"other":""}}}}', true);
$elements = $json['elements'];
foreach($elements as $element){
$pid = $element['pid'];
$styles = $element['styles'];
echo $pid.': '.$styles.'<br />';
}
