accessing hash elements using php

Question

I have a hash array in the form

[{"sector":"Consumer, Cyclical","ticker":"NWY","entity":"New York & Co","New_York_&_Co":[{"count":1,"entity":"New York"}],"type":"SCap"}]

I am trying to list the values corresponding to key value "entity" of all occurences. I did use json_decode,

$testJson = json_decode('[{"sector":"Consumer, Cyclical","ticker":"NWY","entity":"New York & Co","New_York_&_Co":[{"count":1,"entity":"New York"}],"type":"SCap"}]');

When I tried `echo var_dump($testJson[0]);
it shows the output in form

array
  0 => 
  object(stdClass)[438]
  public 'sector' => string 'Consumer, Cyclical' (length=18)
  public 'ticker' => string 'NWY' (length=3)
  public 'entity' => string 'New York & Co' (length=13)
  public 'New_York_&_Co' => 
    array
      0 => 
        object(stdClass)[439]
          ...
  public 'type' => string 'SCap' (length=4)

but echo var_dump($testJson[0]->entity) or echo var_dump($testJson[0]->sector) gives me error.. "Trying to get property of non-object" ..What Could I be doing wrong?

Is the code you tested missing single quotes around the string value, as in the sample? (It should be: json_decode('[{"sector":"Consumer,....) If the posted code isn't representative, please update it. — outis

the input "[{"sector":"Consumer, Cyclical","ticker":"NWY","entity":"New York & Co","New_York_&_Co":[{"count":1,"entity":"New York"}],"type":"SCap"}]" is coming from an array, that should be string right? — user1371896

My point is the sample code wasn't legal PHP. Since it wasn't representative of the code you ran, it also won't have the same issues. (Consider picking a meaningful username so at-replies will work.) — outis

$testJSon= json_decode('[{"sector":"Consumer, Cyclical","ticker":"NWY","entity":"New York & Co","New_York_&_Co":[{"count":1,"entity":"New York"}],"type":"SCap"}]');
//var_dump($testJSon);
echo $testJSon['0']->sector; // will output `Consumer, Cyclical`
echo $testJSon[0]->{'sector'}; // will also output same

and you can convert it in array and get the values like:

$testJSon= json_decode('[{"sector":"Consumer, Cyclical","ticker":"NWY","entity":"New York & Co","New_York_&_Co":[{"count":1,"entity":"New York"}],"type":"SCap"}]',true);
echo $testJSon[0]['entity']; // will return "New York & Co"
