Use json decode to convert the JSON string to a PHP array  then use normal PHP array functions on it    json       var1   9   var2   16   var3   16     var1   8   var2   15   var3   15       data   json decode  json    var dump  data 0   var1        outputs  9

Set the second function parameter to true if you require an associative array  Some versions of php require a 2nd paramter of true if you require an associative array   json        var1   9   var2   16   var3   16     var1   8   var2   15   var3   15       array   json decode   json  true

Decode the JSON string using json decode   and then loop through it using a regular loop    arr   json decode     var1   9   var2   16   var3   16     var1   8   var2   15   var3   15        foreach  arr as  item      foreach element in  arr      uses    item  var1      etc

First you have to decode your json     array   json decode  the json code     Then after the json decoded you have to do the foreach   foreach   array as  key   gt   jsons       This will search in the 2 jsons      foreach  jsons as  key   gt   value             echo  value     This will show jsut the value f each key like  var1  will print 9                           And then goes print 16 16 8               If you want something specific just ask for a key like this  Put this between the last foreach   if  key     var1     echo  value
