json_decode() in PHP not showing true or false statements - php

Question

I have a response coming back that is JSON encoded, but when I decode it I lose the true/false attributes after using $var = json_decode($response);.
Here’s an example:
{
"domain": "my.domain.com",
"created_at": "2014-11-15 00:26:53.74059",
"valid_mx": true
}
I’ve even tried:
$var = json_decode($response, true);
But it still seems to drop the true/false. How can I properly pull the true/false from the response? What am I missing?

Answer 1

Your problem is with print_r, not json_decode.
print_r does not show true / false for true / false. Instead, it shows 1 / (blank).
You can use var_dump($var); or var_export($var); instead which will show you the correct values.

Answer 2

This should work for you:
(With this you have the JSON string as an array)
<?php
$response = '{
"domain": "my.domain.com",
"created_at": "2014-11-15 00:26:53.74059",
"valid_mx": true
}';
$var = json_decode($response, true);
if($var["valid_mx"] === TRUE)
echo "true";
else
echo "false";
?>
Output:
yes
If you want an object just change this line:
$var = json_decode($response, true);
to this:
$var = json_decode($response);
And then you can access it with this line:
if($var->valid_mx === TRUE)

This works for me:
if(json_decode($response)->valid_max){
//your stuff
}
