Array of object as String to Array of object (jSON)?

Question

I'm trying to convert this string :

$json = '[{"a":1,"b":2,"c":3,"d":4,"e":5}, {"a":6,"b":7,"c":8,"d":9,"e":10}]';

To an array of object. I've tried :

$test = json_decode($json, true);
echo sizeof($test); //traces 2 !
echo $test[0]["a"]; //doesn't echo anything!

How do i convert in PHP a json string to an array of object ??

Assuming that json is parsed into an array of objects, try $test[0]->a — Aleks G

Assuming that json is parsed into an array of objects, try

$test[0]->a

You can see this easily with

print_r($test)

which would output

Array
(
    [0] => Array
        (
            [a] => 1
            [b] => 2
            [c] => 3
            [d] => 4
            [e] => 5
        )

    [1] => Array
        (
            [a] => 6
            [b] => 7
            [c] => 8
            [d] => 9
            [e] => 10
        )

)

OP needs to remove the second parameter so that his code is: $test = json_decode($json);

For clarification, if the above output were the OP's output, then accessing an element via $test[0]['a'] should work. However, if the second dimension were stdClass Objects instead of Array as per your output, then accessing an element via $test[0]->a would work.

I tested his json_decode and the output is mine. The second level is object, not array.

json_decode returns an object. To convert the object to an array:

$test = (array)json_decode($json, true);
