How to loop through PHP object with dynamic keys [duplicate]
(16 answers)
Closed 4 years ago.
im working on a project but I ran into a problem :(
I looked on the internet for like 2-3 hours and cannot find the way how to do it...
I retrieve this JSON from my database:
{
"articles": {
"1": {"discription":"Transport", "tax":"21", "price":"234"
},
"2": {"discription":"Opslag", "tax":"19", "price":"19"}
}
}
What I want to do next is retrieve the description,tax & Price from each object, how to do this with a for each loop on the most efficient way?
Thanks!

Answer 1

You can use following code snippet to get value of mentioned keys-
<?php
$str = '{
"articles": {
"1": {"discription":"Transport", "tax":"21", "price":"234"
},
"2": {"discription":"Opslag", "tax":"19", "price":"19"}
}
}';
//convert json to array
$jsonToArray = json_decode($str, true);
foreach ($jsonToArray['articles'] as $value) {
echo $value['discription'] . ' ' . $value['tax'] . ' ' . $value['price'] . PHP_EOL;
}
if you want to access those keys with object then you can proceed with following code snippet-
<?php
$str = '{
"articles": {
"1": {"discription":"Transport", "tax":"21", "price":"234"
},
"2": {"discription":"Opslag", "tax":"19", "price":"19"}
}
}';
//convert json to object
$jsonToObject = json_decode($str);
foreach ($jsonToObject->articles as $value) {
echo $value->discription . ' ' . $value->tax . ' ' . $value->price . PHP_EOL;
}
You are free to make changes in the echo statement that suits your requirement.

$array = json_decode($json_string);
for($i = 0; $i<sizeof($array); $i++) {
echo $array[$i]['description'];
echo $array[$i]['tax'];
echo $array[$i]['price'];
}

Answer 3

You are looking for the json_decode function before you do that, here's an example:
$jsonDecoded = json_decode($jsonInput);
foreach ($jsonDecoded->articles as $item) {
echo $item->discription . "<br>";
echo $item->tax . "<br>";
echo $item->price . "<br>";
}
