title: How to use json_decode to extract an inner information
body: <p>I am new to php. I need some quick help with json_decode/php. I need to get values of g91 in an array, how can I do this? I suppose there is some recursion value that we can pass to json_decode...</p>
  
  <pre><code>{
      "e": "none",
      "f": "test",
      "g": [
          {
              "g1": "text2",
              "g9": {
                  "text3": {
                      "g91": 0,
                      "g92": [
                          "text5"
                      ]
                  }
              }
          },
          {
              "g1": "text1",          
              "g9": {
                  "text4": {
                      "g91": 0,
                      "g92": [
                          "text6",
                          "text7"
                      ]
                  }
              }
