PHP JSON color change depending on value - 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
}
`

Get JSON Data From .json (php)

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

How to filter through this properly?

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'];

PHP and JSON/ How to get a specific elements //

I need to parse a JSON file. I've only worked with XML before.
How can I get the second "food_id" (1730905)?
Here is my JSON file:
{
"shopId":29,
"last":46977914,
"freshfood":[
{
"freshfood_id":2629,
"food":[
{
"food_id":1740851,
"type":"fruit",
"status":1
},
{
"food_id":1730905,
"type":"vegetable",
"status":1
},
]
}
]
}
I tried this, but it does not work.
$string = file_get_contents("food.json");
$json_a=json_decode($string,true);
echo $GetFreshFoodId = $json_a['freshfood'][1]['freshfood_id'];
PHP arrays are zero-based, so that should be:
$json_a['freshfood'][0]['food'][1]['food_id'];
Also, note that the JSON is not entirely valid - you should remove the last comma. (But you might have left out additional records in your example JSON for clarity.)

PHP JSON getting specific value of each key

I have a php code that reads JSON files. Part of the JSON sample below:
"Main": [{
"count": 7,
"coordinates": [89,77],
"description": "Office",
},{
"count": 8,
"coordinates": [123,111],
"description": "Warehouse",
}]
and I am trying to code PHP to only get the info (count, coordinates, description) of those who's description is included in the criteria like Warehouse. PHP Sample below
$validcriteria = array("Warehouse", "Parking_lot");
How do I do an if-statement to check first if "description" is included in the valid criteria. I tried the code below but it doesn't seem to work right.
$JSONFile = json_decode($uploadedJSONFile, false);
foreach ($JSONFile as $key => $value)
{
if (in_array($key['description'] , $validcriteria))
{
#more codes here
}
}
My code in PHP has been working except when I try to add $key['description'] to try and check the description first if it's valid. My code above is reconstructed to remove sensitive information but I hope you got some idea of what I was trying to do.
When attempting to understand the structure of a parsed JSON string, start with a print_r($JSONFile); to examine its contents. In your case, you will find that there is an outer key 'Main' which holds an array of sub-arrays. You will need to iterate over that outer array.
// Set $assoc to TRUE rather than FALSE
// otherwise, you'll get an object back
$JSONFile = json_decode($uploadedJSONFile, TRUE);
foreach ($JSONFile['Main'] as $value)
{
// The sub-array $value is where to look for the 'description' key
if (in_array($value['description'], $validcriteria))
{
// Do what you need to with it...
}
}
Note: if you prefer to continue setting the $assoc parameter to false in json_decode(), examine the structure to understand how the objects lay out, and use the -> operator instead of array keys.
$JSONFile = json_decode($uploadedJSONFile, FALSE);
foreach ($JSONFile->Main as $value)
{
// The sub-array $value is where to look for the 'description' key
if (in_array($value->description, $validcriteria))
{
// Do what you need to with it...
}
}
You might also consider using array_filter() to do the test:
$included_subarrays = array_filter($JSONFile['Main'], function($a) use ($validcriteria) {
return in_array($a['description'], $validcriteria);
});
// $included_subarrays is now an array of only those from the JSON structure
// which were in $validcriteria
Given your JSON structure, you probably want
foreach($decoded_json['Main'] as $sub_array) {
if (in_array($sub_array['description'], $validation)) {
... it's there ...
}
}
Because you set false to second argument of json_decode function, it's returned as an object,
if you change it to TRUE, the code would work.
http://php.net/manual/en/function.json-decode.php
and you have to change key to value;
foreach ($JSONFile->Main as $key => $value)
{
if (in_array($value->description, $validcriteria))
{
#more codes here
}
}
this code assume your json file has one more depth greater than your example. that's why $JSONFile->Main in the foreach loop.
Try to use that :
if ( array_key_exists('description', $key) )

If ARRAY value, use other ARRAY value

{
"Group": [
{
"name": "HolderOne",
"operators": [
{
"username": "ken",
"status": 3
},
.....etc.....
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;
}
}
}
