issues when looping throw a json on php - php

Question

this is driving me nuts,
I'm trying to loop throw a specific json:
I tried using
json_encode -> throws Warning: curl_close() expects parameter 1 to be resource, null given
json_decode -> shows the same text
$json->{"SKU"} and $json->SKU shows the same text
I tried to validate the json with different websites and all say the json is correct
I want to take only this values SKU, price, specialprice (with everything inside) and quantity
[{

"BrandName": "DIVIDED",

Thanks a lot for any hint (I already tried almost every answer on stack)

Answer 1

I'm pretty sure you can do it in this way:
<?php
//Enter your code here, enjoy!
$text = <<<EOT
[{
"SKU": "118075",
"BrandName": "DIVIDED",
"CategoryName": "Correas",
"Categories": [{
"Id": "423",
"CategoryName": "Moda",
"LevelDepth": "2",
"Parent": null
}, {
"Id": "960",
"CategoryName": "Accesorios de Mujer",
"LevelDepth": "3",
"Parent": "Moda"
}],
"Name": "Divided correa Carrie",
"Description": "a",
"DescriptionShort": "v",
"MetaDescription": "Correa Divided Carrie en presentaci\u00f3n de tres colores.",
"MetaTitle": "Divided Correa Carrie",
"IsPublished": "1",
"PackageWeight": "1.000000",
"Price": 39.9,
"FinalPrice": 16.3,
"SpecialPrice": {
"StartDate": "2014-11-21 06:00:00",
"EndDate": "2017-12-31 23:59:00",
"Reduction": "20.000000",
"ReductionType": "amount"
},
"Quantity": "39",
"DateAdd": "2015-09-24 11:26:08",
"DateUpd": "2016-10-12 12:51:13",
"Images": [{
"Id": "77",
"Cover": "1",
"Legend": "Divided correa Carrie",
"url": "https:\/\/www.google.com.pe\/img\/p\/7\/7\/77.jpg"
}, {
"Id": "78",
"Cover": "0",
"Legend": "Divided correa Carrie",
"url": "https:\/\/www.google.com.pe\/img\/p\/7\/8\/78.jpg"
}, {
"Id": "79",
"Cover": "0",
"Legend": "Divided correa Carrie",
"url": "https:\/\/www.google.com.pe\/img\/p\/7\/9\/79.jpg"
}],
"FlatVariations": [{
"SKU": "001503280",
"Price": 39.9,
"FinalPrice": 16.3,
"Default": "1",
"IdImage": "77",
"Attributes": [{
"Name": "Color",
"Value": "Naranja"
}]
}, {
"SKU": "001503281",
"Price": 39.9,
"FinalPrice": 39.9,
"Default": "0",
"IdImage": "78",
"Attributes": [{
"Name": "Color",
"Value": "Blanco"
}]
}, {
"SKU": "001503282",
"Price": 39.9,
"FinalPrice": 39.9,
"Default": "0",
"IdImage": "79",
"Attributes": [{
"Name": "Color",
"Value": "Negro"
}]
}]
}]
EOT;
$decoded = json_decode($text);
# Index 0 because is an array
var_dump($decoded[0]->SKU);
You can execute the code directly here.
Hope this helps.
