JSON Parse Error: Expecting 'STRING' - json

Question

I am using JSONLint to parse some JSON and i keep getting the error:
Error: Parse error on line 1:
[{“ product”: [{“
---^
Expecting 'STRING', '}', got 'undefined'
This is the code:
[
{
“product” : [ { “code” : “Abc123”, “description” : “Saw blade”, “price” : 34.95 } ],
“vendor” : [ { “name” : “Acme Hardware”, “state” : “New Jersey” } ]
},
{
“product” : [ { “code” : “Def456”, “description” : “Hammer”, “price” : 22.51 } ],
},
{
“product” : [ { “code” : “Ghi789”, “description” : “Wrench”, “price” : 12.15 } ],
“vendor” : [ { “name” : “Acme Hardware”, “state” : “New Jersey” } ]
},
{
“product” : [ { “code” : “Jkl012”, “description” : “Pliers”, “price” : 14.54 } ],
“vendor” : [ { “name” : “Norwegian Tool Suppliers”, “state” : “Kentucky” } ]
}
]

Answer 1

JSON string literals must use normal quote characters ("), not smart quotes (“”).

Answer 2

You're using some unicode double quotes characters. Replace them with the normal " double quotes.
You also had some extra comma at the end in the second element.
Now it's alright
[
{
"product" : [ { "code" : "Abc123", "description" : "Saw blade", "price" : 34.95 } ],
"vendor" : [ { "name" : "Acme Hardware", "state" : "New Jersey" } ]
},
{
"product" : [ { "code" : "Def456", "description" : "Hammer", "price" : 22.51 } ]
},
{
"product" : [ { "code" : "Ghi789", "description" : "Wrench", "price" : 12.15 } ],
"vendor" : [ { "name" : "Acme Hardware", "state" : "New Jersey" } ]
},
{
"product" : [ { "code" : "Jkl012", "description" : "Pliers", "price" : 14.54 } ],
"vendor" : [ { "name" : "Norwegian Tool Suppliers", "state" : "Kentucky" } ]
}
]

Answer 3

JSON must use normal quote characters("), not smart quotes for(“”) for string literals.
To get the normal quote in JSON data format:
right-click on browser window and select - view page source.

Answer 4

This is how I save the MySQL text format and get the json_decode data
[{"5":[29,30,5],"6":[1,2,3],"7":[4,5,6]}]
$row_days= $rows['days'];
var_dump(json_decode($row_days, true));
Result array (size=1)
0 => array (size=3) 5 => array (size=3) 0 => int 29 1 => int 30 2 => int 5 6 => array (size=3) 0 => int 1 1 => int 2 2 => int 3 7 => array (size=3) 0 => int 4 1 => int 5 2 => int 6

Answer 5

Many times this error is caused by doing:
object.age = 31
instead of the correct way:
object["age"] = 31
