To cut a long story short, I'm wanting to check the return value of the json_encode function - therefore if its false I can throw an exception. What do I find? The lovely json_encode returns false as a string if it fails!

php Code:

$aJson = json_encode($szContent);

if(!$aJson)
{
    throw new Exception('Badly formatted JSON returned');
}

That won't work because it's a string, and I can't typecast it using (bool) because the string will be seen as a true value. Here's the result from var_dump when json_encode fails:

Quote:

string(5) "false"

Does anybody have any idea? I don't want to just do it like the following as that would be very silly indeed.

php Code:

if($aJson == 'false')
{
    
}
