Hi all,
I've succesfully pulled data out of my JSON feed thanks the help on SO...but...scratching my head now.
By using print_r($obj->....) I am able to extract all information from my feed BUT what I want to be able to do is...
From above, if the value of username is 'ken' then only display the associated status 3.
I think it could be using the value the print_r assigns each Array(?) e.g. above would be [0] - now I don't know what the value would be so can I grab the [n] value for each username to display the status?
I am slightly outside my comfort zone here...not sure if it's a PHP or JSON problem for a start.
Thanks in advance for any help
Is this what you are looking for?
foreach($obj->Group as $group)
{
foreach($group->operators as $operator)
{
if($operator->username == "ken")
{
echo $operator->status;
}
}
}

i'm trying to get the fields "name, price, image and rarity" to show in a php file, anyone can help me? Thanks ;D
{
"status": 300,
"data": {
"date": "2019-09-16T00:00:00.000Z",
"featured": [
{
"name": "Flying Saucer",
"price": "1,200",
"images": {
"icon": icon.png",
},
"rarity": "epic",
},
I'm using this that a friend told me, but i cant put that to work :c
<?php
$response = json_decode(file_get_contents('lista.json'), true);
foreach ($response as $val) {
$item = $val['name'];
echo "<b>$item</b>";
}
?>
I'm not quite sure what you are trying to achieve. You can just access the contents via the $response array like this:
echo $response['status']; // would output 300
You can use foreach to iterate through the array. For example: If you want to output the name of every element of the array you can use:
foreach ($response['data'] as $val) { // loop through every element of the data-array (if this makes sense depends on the structure of the json file, cant tell because it's not complete)
echo $val['featured']['name'];
}
You gotta get the index in $val['data']['featured']['name'] to retrieve the name index.
When you defined the second parameter of json_decode, you said that you want your json to be parsed to an array. The brackets in the original json identify when a new index of your parsed array will begin.
I suggest you to read about json_decode and json in general:
JSON: https://www.json.org/
json_decode function: https://www.php.net/manual/en/function.json-decode.php
I want to change the number color depends on number value from json object.
Example this is my json file.
{
"status": "ok",
"meta": {
"count": 1
},
"data": {
"521997295": {
"global_rating": 4647
}
}
}
If the global rating number is lower than 1000 i want to display green. If it is higher red ect... It must be in php script. How do i do that? Thank you for help.
First, you will need to use json_decode() function to read the JSON data as an object or array.
Then from the object or array, you will need to get the value of 'global_rating'.
After that, you can use conditional logic to do the things as you want. For example:
`<?php
if($global_rating < 1000) {
// font-color = green
} else {
// font-color = red
}
`
I am wondering how to filter through a result like this properly. What I am doing results in problems. Obviously using a foreach on an array with a single item is not ideal but I don't know exactly how to do it any other way.
// connect with the static file
$json = file_get_contents('resources/assets/datafeeds/brewery_single.json');
$obj = json_decode($json, true);
// create brewery info
foreach($obj['pages'] as $brewery) {
foreach($brewery['results'] as $brewery) {
}
}
I've tried doing something like:
foreach($obj['pages']['results'] as $brewery) {
}
But I get an Undefined index: result errror like this.
Example data with only one result block, my data has multiple:
{
"apiName": "brewery_single",
"apiGuid": "d74e8aa2-4064-44b9-81de-2ceb150882c0",
"generatedAt": 1452761620,
"pages": [
{
"pageUrl": "http://www.brewery-website.com",
"results": [
{
"website": "www.brewery.com/",
"plaats": "Place",
"latlong": [
"53.657856",
"5.032597"
],
"naam": "Brouwerij title",
"provincie": "Noord Brabant",
"afbeelding": "http://www.brewery.com/images/brewery/brewer.jpg",
"actief": "Yes",
"land": "Netherlands",
"adres": "<p><b>Adres:</b><br />Street 40 <br />2388 GP<br /> Province, Netherlands </p>",
"opgericht": "1990"
}
]
},
]
}
Hopefully somebody can help me out so I can properly get my data from an api.
It seems like pages is an array of potentially multiple pages, each of which contains a results array of potentially multiple results. So indeed, two loops are in order:
foreach ($obj['pages'] as $page) {
foreach ($page['results'] as $brewery) {
...
}
}
If you're only ever interested in the first result, you can try to directly access it:
if (isset($obj['pages'][0]['results'][0])) {
echo $obj['pages'][0]['results'][0]['plaats'];
}
But again, the point of this data structure appears to be to account for multiple results, so you may be missing out on some information if you only ever consider the first.
Consult the documentation (which hopefully exists) of that API for exact details on the returned data.
Add an extra check to see if the data that you want is in the array:
if (isset($obj['pages'])) {
foreach($obj['pages'] as $brewery) {
if (isset($brewery['results'])) {
foreach($brewery['results'] as $brewery) {
}
}
}
}
There is syntax error in your code near ['results]
Change from
foreach($obj['pages']['results] as $brewery) {
into
foreach($obj['pages']['results'] as $brewery) {
There is no multiple arrays in results array. So why you need foreach there?
Anyways you can get value of results by providing exact INDEX.
For example: echo $obj['pages']['results]['website'];
I have a JSON file that, in essence, is structured like this:
[{
"name": "James",
"reviews": [
{
"stars": 5,
"body": "great!"
},
{
"stars": 1,
"body": "bad!"
}
]
},
{
"name": "David",
"reviews": [
{
"stars": 4,
"body": "pretty good!"
},
{
"stars": 2,
"body": "just ok..."
}
]
}]
Now when positing new review data for David to a PHP script, how do I target David's specific "reviews" and append it?
I have already decoded everything correctly and have access to both the decoded file and post information. I just don't know how to target David's specific reviews in the JSON array... Thank you in advance!
UPDATE - Just to be clear, everything is decoded already, the POST data and the JSON file from the server. I just need to know how to target David's reviews specifically and append it.
UPDATE 2 - Everyone, please also understand that this is in the case that the index is not known. Doing [1] would be awesome, but when someone submits, they won't know what index it is. The loop for the rendering is being done in AngularJS btw, so can't assign anything on the PHP side for the front-end.
You will have to make use of a for-loop/foreach to iterate through the array testing where arr['name'] === 'David',
then you can access arr['reviews'].
foreach ($array as $person)
{
if ($person['name'] === 'David')
{
$person['reviews'][] = array("stars"=> 3,"body"=> "pretty cool!");
break;
}
}
Edit:
You could also make a generic function for this
function findElem(arr,field,e)
{
foreach ($arr as $elem)
{
if ($elem[field] === e)
{
return $elem;
}
}
return null;
}
to call:
$elem = findElem(myArray,'name','David');
if ($elem !== null)
$elem[] = array("stars"=> 3,"body"=> "pretty cool!");
Looks like more work, but if you are going to do it repeatedly then this helps.
PHP >= 5.5.0 needed for array_column or see below for an alternate:
$array[array_search('David', array_column($array, 'name'))]['reviews'][] = array(
'stars'=>1,'body'=>'meh'
);
Instead of array_column you can use:
array_map(function($v) { return $v['name']; }, $array);
If you want specifically david's reviews, and only david's reviews... assuming that $array holds the json_decoded array:
$david_reviews = $array[1]["reviews"];
foreach($david_reviews as $review){
//Do code to retrieve indexes of array
$stars = $review["stars"] //5
$body = $review["body"] //Great!
}
If you're looking to grab reviews for each result, then user2225171's answer is what you're looking for.
json_decode($json, true) will return you the simple array of data. Then save what you need and save back with json_encode()
I'm trying to pull the price from the following JSON but can't seem to figure out how to reference the actual values:
{"cards": [ { "high": "0.73", "volume": 1, "percent_change": "-2.67", "name": "Lightning Bolt", "url": "http://blacklotusproject.com/cards/Revised+Edition/Lightning+Bolt/", "price": "0.73", "set_code": "3ED", "average": "0.73", "change": "-0.02", "low": "0.73"}], "currency": "USD" }
So far I've got this code, which gets into the cards array but I'm unsure how to get farther - every attempt I've tried returns null.
$json = file_get_contents($url); $data = json_decode($json, TRUE);
echo var_dump($data[cards]);
Can someone shed light on what I need to do?
$data['cards'] has another array within it. You will need to access this array with index 0. For instance, $data['cards'][0]['high'] and so on.
$data['cards'] is an array itself, so you could do:
foreach ($data['cards'] AS $carditem) {
echo $carditem['high'];
...
}
to get all items in that array,
or if you only want the first item $data['cards'][0]['...']
To access using a string literal array index, always use quotes.
$data["cards"]
