        \"clientId\":\         


        

Answer 1

I know there is already an answer to this but it may be worth noting that var_dump outputs Boolean values better it just has worse formatting IMO.

<pre>
    <?php
        print_r(array(true, false));
        var_dump(array(true, false));
    ?>
</pre>

Results in

Array
(
    [0] => 1
    [1] => 
)
array(2) {
  [0]=>
  bool(true)
  [1]=>
  bool(false)
}

Answer 2

you can use it like this, in JSON format when you evaluate false value it will give you blank, and when you evaluate true it will give you 1.

$str = '[{"clientId":"17295c59-4373-655a-1141-994aec1779dc","channel":"\/meta\/connect","connectionType":"long-polling","ext":{"fm.ack":false,"fm.sessionId":"22b0bdcf-4a35-62fc-3764-db4caeece44b"},"id":"5"}]';

$arr = json_decode($str,true);

if($arr[0]['ext']['fm.ack'])    // suggested by **mario**
{
    echo "true";    
}
else {
    echo "false";   
}

It's a very simple. If you use js to generate and transfer json, pass your variable not in its pure form but: youBoolVar + 0, then false will be 0, and true 1
