I have decoded a JSON file into a variable ( $tmp
). var_dump($tmp)
gives:
object(stdClass)#31 (3) {
["c"]=> int(2)
["r"]=> int(2)
["d"]=> object(stdClass)#32 (4) {
["1"]=> string(2) "un"
["2"]=> string(4) "deux"
["3"]=> string(5) "trois"
["4"]=> string(6) "quatre"
}
}
I want to retrieve for example "un" so I do $tmp->d["1"]
but it doesn't work. I've got the following error:
Fatal error: Cannot use object of type stdClass as array in File.php on line 17
json_decode takes an additional paramater that will turn your json string into an array instead of an object
json_decode($json_str, true)
As comment noted, your d
property of your json object is an object not an array, so you can't access it with array notation (as you see there is an error)
I believe
$tmp->d->{'1'}
// "un"
should work in accessing it
php has a default function json_encode and json_decode
$arrayOfValues = array();
$jsonString = json_encode($arrayOfValues);
and
$arrayOfValues = json_decode($jsonString);
with this function you can use variabled with json.
