Assign Json to php Variables -

i want make json details dynamic.currently static.as example want declare few php variables these json.

here code

$body = '{   "outboundsmsmessagerequest": {     "address": [       "tel:+9456654978"     ],      "senderaddress": "tel:+95623654978",     "outboundsmstextmessage": {       "message": "welcome fgf  confirmation code - "     },      "clientcorrelator": "",     "receiptrequest": {       "notifyurl": "",       "callbackdata": ""     },     "sendername": ""   } }'; 

as in here can see json has declared $body.what want make separate variables such $message,$address, $senderaddress , assign them $body. how can this?

initial json:

 $body = '{       "outboundsmsmessagerequest": {         "address": [           "tel:+9456654978"         ],          "senderaddress": "tel:+95623654978",         "outboundsmstextmessage": {           "message": "welcome fgf  confirmation code - "         },          "clientcorrelator": "",         "receiptrequest": {           "notifyurl": "",           "callbackdata": ""         },         "sendername": ""       }     }'; 

decode json array

i use second parameter true because need array associative.

$arr = json_decode($body, true); 

now insert necessary value:

$arr['outboundsmsmessagerequest']['address'] = "tel:+1234567890"; $arr['outboundsmsmessagerequest']['senderaddress'] = "tel:+0987654321";  $arr['outboundsmsmessagerequest']['outboundsmstextmessage']['message'] = "test message"; 

now encode array json

$body = json_encode($arr); 

output

print_r($body); 

result

{"outboundsmsmessagerequest":{"address":"tel:+1234567890","senderaddress":"tel:+0987654321","outboundsmstextmessage":{"message":"test message"},"clientcorrelator":"","receiptrequest":{"notifyurl":"","callbackdata":""},"sendername":""}}
