PHP get json data with json_decode - php

Question

I'm new to PHP and try to echo out some data from json, but I got stucked in this.
It shows non of the data, but the data is there. The var_dump() shows it to me.
Probably I don't use the array correctly, but I can't find what's wrong. I've this code,
I request some data which I gathered with knockout.js
Knockout gives me a json (as show below)
$json = $_REQUEST[seats];
echo 'requested data raw '. "<br>".$json;
$data = json_decode($json, true);
echo "<br>".'var_dump '. "<br>";
var_dump($data);
foreach ($data as $optie ) {
echo "name = " . $optie->name . "<br>";
echo "optie = " . $optie->optieName . "<br>";
echo "prijs = " . $optie->prijs . "<br>";
}
This is my JSON:
[
{
"name": "Naam 1",
"optie": {
"optieName": "Make_up",
"prijs": 9.95
},
"PrijsFormated": "Euro: 9.95"
},
{
"name": "Naam 2",
"optie": {
"optieName": "Handverzorging",
"prijs": 12.95
},
"PrijsFormated": "Euro: 12.95"
}
]

Answer 1

You should use such loop:
foreach ($data as $optie ) {
echo "name = " . $optie['name'] . "<br>";
echo "optie = " . $optie['optie']['optieName'] . "<br>";
echo "prijs = " . $optie['optie']['prijs']. "<br>";
}
Because using json_decode() with second parameter as true you have created associative array - documentation.
If you would like to access data as object, you should use:
$data = json_decode($json);
instead of
$data = json_decode($json, true);
and then you should use the following loop:
foreach ($data as $optie ) {
echo "name = " . $optie->name . "<br>";
echo "optie = " . $optie->optie->optieName . "<br>";
echo "prijs = " . $optie->optie->prijs. "<br>";
}
