Accessing JSON array after json_decode/multidimensional array
(3 answers)
Closed 8 years ago.
I am receiving a multilevel json like this:
{"id":"3",
"field2":"ssss",
"field3":[
{"field31":"wwwww",
"field32":"qqqq"},
{"field31":"wwwww",
"field32":"qqqq"},
{"field31":"wwwww",
"field32":"qqqq"},
]}
I am reading json values (first level) like this in php:
$json = file_get_contents('php://input');
$json_post = json_decode(utf8_decode($json), true);
$id = $json_post['id'];
But I don't know how to get the json in the second level. What is the simplest way? I just need to get the json in other variable like $json_post, I will read it in a for bucle to get each row of the json file
It's going to give you a PHP object if you run json_decode(utf8_decode($json));
echo $json_post->field3->field31;
EDIT: I missed that you were using the conversion to array. This is what the array would look like
echo $json_post['field3']['field31'];

How to extract and access data from JSON with PHP?

I get this kind of string from JS to PHP.
[[1,"10.00","10.00","A"],[2,"20.00","25.00","B"],[3,"10.00","25.00","C"],[6,"10.00","25.00","D"]]
How can I convert it to a php multidimensional array?
Note:
I tried json_encode without getting the desired result.
<?php
$string = '[[1,"10.00","10.00","A"],[2,"20.00","25.00","B"],[3,"10.00","25.00","C"],[6,"10.00","25.00","D"]]';
$result = json_decode($string);
var_dump($result);
?>
You should use json_decode instead of json_encode for convert JSON to array PHP

How to extract and access data from JSON with PHP?

Closed 2 years ago.
I have an JSON Export from a REDCap and it started as a nested ARRAY. I use json_decode, but when I print the result I get an ERROR.
Here is the Array:
[{"record_id":"13","lastname":"Mustermann","first_name":"Json","dob":"1948-10-12","case_number":"1366613"}]
My Code is:
$deco = json_decode($json);
print $deco;
The line "echo" gives an error. What am I doing wrong?!
Thank you

Need help. I am having trouble solving this json thingy. here's what is on my database
{"img":["images/logo2.png","images/logo.png"]}
I need to decode this images and show it like this
images/logo2.png
images/logo.png
A quick google search will give you this link: json_decode.
$someJson = '{"img":["images/logo2.png","images/logo.png"]}';
$encodeJson = json_decode($someJson, true);
echo $encodeJson['img'][0]; //images/logo2.png
echo $encodeJson['img'][1]; //images/logo.png
Hint: Having a look at the PHP-Manual is not prohibited. ;)
Maybe select your entry from database and put in a variable called $dataBaseEntry then copy paste this code?
$decoded = json_decode($dataBaseEntry, true); //true for associated array
$logos = $decoded['img'];
print_r($logos)

I have a JSON output that looks like this:
{"data":[{"QID":"Q1234","MgrQID":"5678","NTID":"blah"}]}
I am trying to access just the data within the square brackets, inside the data array?
I have tried $jsonVar['data'] and $jsonVar->data and neither of them are working.
Is there a way I can just get access to [{"QID":"Q1234","MgrQID":"5678","NTID":"blah"}]?
Try this example:
<?php
$data = '{"data":[{"QID":"Q1234","MgrQID":"5678","NTID":"blah"}]}';
$test = json_decode($data, true);
echo json_encode($test['data']);
?>
Output:
[{"QID":"Q1234","MgrQID":"5678","NTID":"blah"}]

I have a json text like this:
$text ='{"id":"12","count":"1","1":{"gkey":"g_c5218"},"0":{"gkey":"g_4b4c6"}}';
I want convert it to array:
$arr = json_encode($text,true);
Now I want call $arr['id'] But I get index error.
what is my wrong?
json_encode() - change an array to the json
json_decode() - change json to the array/object
You should use json_decode.
