Convert JSON value to PHP string -


need value "distance" "text" google maps api, , convert php string.

for example, https://maps.googleapis.com/maps/api/distancematrix/json?origins=tn222af&destinations=tn225dj&mode=bicycling&language=gb-fr&sensor=false&units=imperial gives us:

{    "destination_addresses" : [ "new town, uckfield, east sussex tn22 5dj, uk" ],    "origin_addresses" : [ "maresfield, east sussex tn22 2af, uk" ],    "rows" : [       {          "elements" : [             {                "distance" : {                   "text" : "3.0 mi",                   "value" : 4855                },                "duration" : {                   "text" : "22 mins",                   "value" : 1311                },                "status" : "ok"             }          ]       }    ],    "status" : "ok" }
