PHP Notice: Array to string conversion when echoing json_decode()'ed data - php

Question

I have this code in a.json:
{
"body" : {
"outboundSMSMessageRequest": {
"address": [
"9456654978" /* 1 */
],
"senderAddress": " 64735 ", /* 3 */
"outboundSMSTextMessage": {
"message": "Welcome to fgf Your Confirmation Code - " /* 2 */
},
"clientCorrelator": "1", /* 4 */
"receiptRequest": {
"notifyURL": "2", /* 5 */
"callbackData": "3" /* 6 */
},
"senderName": "4" /* 7 */
}
}
}
I want to print the values as marked above (1, 3, 2, 4, 5, 6, 7, the values only). I have tried this:
$jsonData = file_get_contents("a.json");
$json = json_decode($jsonData,true);
echo $json;
but I end up with the following notice:
PHP Notice: Array to string conversion
How can I print the values as desired?

Answer 1

Presumably by:
I want to in a PHP page to print (1, 3, 2, 4, 5, 6, 7, the values only)
... you mean those values you've marked with the numbered comments, e.g. /* 1 */ - if so, this should do the trick (to just echo it out anyway).
$jsonData = file_get_contents("a.json");
$o = json_decode($jsonData);
$outboundSMSRequest = $o->body->outboundSMSMessageRequest;
echo $outboundSMSRequest->address[0] . "\n" // outbound address
. $outboundSMSRequest->outboundSMSTextMessage->message . "\n" // outbound message
. $outboundSMSRequest->senderAddress . "\n" // sender address
. $outboundSMSRequest->clientCorrelator . "\n" // client correlator
. $outboundSMSRequest->receiptRequest->notifyURL . "\n" // notification URL
. $outboundSMSRequest->receiptRequest->callbackData . "\n" // callback data
. $outboundSMSRequest->senderName; // sender name
When you use json_decode() you turn the JavaScript object into a PHP object - so you just access it accordingly.

Json do not support comments so you need to remove them from your file,
see Can comments be used in JSON?
